Thermalright is a name that has been synonymous with enthusiast-level air cooling for quite a while now. Their venerable Ultra 120 Extreme (aka the TRUE) has won accolades and was once the favorite high end air cooler among overclockers worldwide. In recent times, the TRUE has fallen behind a little bit. While still one of the top air coolers, it’s not quite standing alone on the podium as it once was.

Thermalright aims to up their game with the recently released Venomous X, which we’re going to have a look at today.

Specifications

The Venomous X is nothing if not impressive on paper. The specs outlined on Thermalright’s site are:

  • All new patented multiple support pressure vault bracket system, allow users adding pressure to the bracket system (40~70 lbs. ), and have a more efficient and secure mounting.(1366 / 1156 / 775).
  • Mirrored copper base improves the performance of the heatsink.
  • Special bent winglet design allows hot air to pass through the heatsink more rapidly.
  • Nickel plating designed to ensure long-term quality and performance.
  • Soldered heatpipes, copper base and fins, to ensure the best thermal conducting efficiency.
  • Six sintered heatpipe design. All heatpipes are nickel plated to slow oxidation of the heatpipe; this ensures a longer lifetime and higher performance of the heatsink.
  • Includes 2 sets of 120 x 25mm fan clips and Chill factor II thermal paste.
  • Convex copper base design to improve contact between the cpu and the heatsink.

So far it looks like a very strong contender. Let’s see how it looks!

Packaging

The cooler comes in an elegant, if understated package. The box of accessories and the cooler are encased nicely in foam inside a matte black cardboard box emblazoned with a metallic green Venomous X label.

Opening the Box

First Look at the Cooler

Accessories & Mounting Hardware

The accessories pack contains all of the essential if you use a current-generation Intel CPU.  However, if you want to use it on an AMD CPU you’ll have to buy an additional bracket. If you use an Intel CPU from any recent socket – be it 775, 1156 or 1366 – you have a very strong, user-friendly mounting bracket. In addition to the bracket you get two sets of fan clips (rated to work on 25mm thick fans but they work fine on 38mm thick fans).

Accessory Pack

Accessories

The mounting mechanism is quite intuitive.

  • First you set the back plate to the proper socket. This is easily accomplished with simply clicking the mounting screw in the right place.
  • Once the plate is behind the motherboard, you secure it with the first set of thumb screws.
  • Place the bracket on these and secure it with the second set.
  • Then you’ll mount the cooler (not pictured) and use the crossbar to secure it in place.
  • Once mounted you can use the supplied wrench to tighten the torque to your liking. For all tests in this review, the torque screw was cranked down as far as it would go.

Back Plate

Mount Assembly

Once mounted, it’s definitely not going anywhere. The cooler feels very secure and thermal paste was consistently spread evenly across the chip every time the cooler was mounted.

The Cooler

This isn’t the largest cooler on the market, but it is still quite sizable. Measuring 127mm long x 63mm wide x 160mm tall, it’s quite an impressive sight. Add to that the fact that the heatsink itself (not including fan brackets, fans or the mounting system) weighs 755g – that’s one and two-thirds pounds  – and you have one beastly cooling machine.

As hardware goes, it’s quite nice to look at. The finish is impeccable and would complement anyone’s hardware well.

Cooler Straight On

Cooler at an Angle

Cooler Angle Two

The six 6 millimeter heatpipes are staggered so that they’re not in a straight line when mounted in the fins, presumably to help cooling by getting airflow on the actual heatpipes and not just on the fins they’re attached to.

The fins themselves are angled at their edges. Thermalright says this is their “special bent winglet design, [that] allows hot air to pass [through] the heatsink more rapidly.”

In the photo on the left, if you look at the top of the base you can see the hole where the torque screw applies its pressure. It’s nice they did this in addition to making the bracket bend over the base. It makes mounting it in the right place that much easier.

Closer Look at the Base

Heatpipe Terminations

The base is lovely to behold. Smooth and shiny thanks to the nickel plating, it is a very nice way to end our tour of the bare heatsink.

Base a Little Closer

Fan Mounting

Installing fans with the supplied clips is a breeze. There are holes in the fins to put the end of the clips in. Place your fan in the (very convenient) grooves that hold it in place horizontally and pull them over. There are photos both with one and two 38mm thick fans attached.

With two 38mm thick fans, this thing goes from formidable to insanely large: unfortunately too large. In a sad turn of events, the only decent fans available for testing at the time were 38mm thick. While this is almost always a good thing, in this case it was a detriment. The 38mm ‘push’ fan did not fit over my system’s rather tall RAM (G.Skill Trident series) heatsinks. Sadly, this means the only testing that could be done was with one (very powerful) fan in pull.

For reference, below are the  width measurements with both types of fan in one- and two-fan configurations. Note this chart does not include measurements for grilles.

Fan Size: 25mm 38mm
Single Fan Width 86mm 99mm
Double Fan Width 110mm 135mm

Fortunately, the fan in question is an Ultra High Speed Panaflo, model # FBA12G12U1BX. This is a very powerful 120mm x 38mm fan, running at 2750RPM and moving 114CFM of air. Even one should be more than sufficient to gauge this heatsink’s performance.

Unfortunately, due to logistical concerns, I was unable to photograph the installed cooler – I will be doing follow up testing (on a different CPU, testing push/pull/push-pull stuff with 25mm fans) and will post a photo when that happens.

Testing Methodology

The CPU being cooled for this review is an Intel i7 860 – a furnace of a CPU. If you really want to test a cooler, an i7 is the way to do it. Tests were run at three speeds: stock, a moderate overclock (3.6GHz) and finally at 3.8GHz. The machine in question runs stable at 3.8 GHz 24/7.

The Venomous X is being compared in this review to results obtained in the previous review of the Corsair H50 on this same system. You may recall that I said the H50 was “Quieter than air cooling with equal or slightly better temperatures.” Time to put my money where my mouth is and see if that assumption was correct.

For reference, results at stock speed are also compared against the stock Intel cooler. At stock and overclocked other values were obtained from a custom water loop for comparison. This consisted of:

  • Swiftech MCP-355 pump with XSPC reservoir top.
  • Swiftech MCR-320 radiator, mounted externally with three Ultra High Speed Panaflo fans running at 7V (+/-. 1V) for all tests.
  • Swiftech Apogee XT water block.
  • All linked with Primchill Pro LRT 7/16″ inner diameter tubing.

Of course, bear in mind when viewing the results that the water loop is way (way) more expensive than anything else compared here, coming in at $270 – and that’s not including tubing and barbs. The H50, however, is at a very similar price point (~$65) to the Venomous X once you include some quality fans.

The Prime95 Small FFT test was the punishment of choice to stress the CPU for obtaining load temperatures and was run for a minimum of thirty minutes. CPU temperatures were measured using Coretemp’s logging function and ambient was measured with a common room thermometer to the nearest 0.5ºC.

The thermal interface material used was the included Thermalright Chill Factor II. Since this did not come pre-installed (which is a good thing), the cooler was mounted three times and temperatures reported below are the average of all three runs. The difference between runs was minimal. The mounting system included with this cooler is excellent, providing uniform TIM contact very consistently.

The first five minutes of the temperature results were discarded (to allow the cooler time to warm up) and the remaining results were averaged, over the subsequent time, for each core. Presented in the graphs are the average of all four cores at idle, the average load temperature of all four cores and the average maximum temperature of all four cores. All data were obtained from averaging the three runs together.

Rather than present you with a deluge of data and screenshots, below are some graphs to make it easier to digest. All temperature results were normalized to 22ºC ambient (per the esteemed Vapor, “…ambient and core temps scale perfectly fine (1:1) with i7.”) Of course, for anyone that likes to pour through screenshots and excel spreadsheets, the test data can be downloaded in its entirety right here (it’s about 6.5MB).

For comments on how temperatures were measured on the competition, please refer to the H50 review testing methodology.

Results

Now, without further ado, let’s see how the Venomous X performs! We’ll start off with stock testing.

Stock Temperature Graph

Predictably, the stock cooler is woefully inadequate to deal with the heat output of the CPU it was bundled with. The custom loop is, of course, the best (a trend repeated across all of the results, so this is the last you’ll hear of it). What is somewhat surprising here is that the Venomous X is actually outperforming the H50 under load!

Moving on, let’s have a look at how it copes with a decent overclock. The i7’s are hot to start with, but once you kick them into higher gear by overclocking a few hundred MHz, they really put out some heat.

3.6GHz Temperature Graph

The Venomous X still out-performs the H50 – even when you replace its fan with a much stronger high speed Yate Loon fan.

It is important to note that the high speed fan on the H50 is a fair bit quieter than the one on the Venomous X – going back to my point in the H5O review: The H5O will perform about equally well as a good air cooler, but will be a bit quieter. Let’s see what happens when you throw a couple hundred more MHz into the mix.

3.8GHz Temperature Graph

The Venomous X finally falters, but by only a little. It’s still performing just about equal to an entry level water cooling option, which is not bad at all! Temperatures are still in the acceptable range and those that are willing to push the envelope a little more could probably squeeze out a greater overclock with decent results.

Conclusion

What is there to say that the numbers didn’t already prove? This is most definitely a very good heatsink, holding its own even versus a very popular entry-level water cooling unit.

Pros

  • Great appearance.
  • Stunningly smooth base.
  • Excellent mounting system.
  • Stellar performance.

Cons

  • No fans included.
  • Size could be a factor in some situations. Hardly a con if you pay attention and measure your space first though.

The Venomous X is available for roughly $65 ($63. 99 at CrazyPC, $62.95 at Sidewinder, $69.95 at Jab-Tech). Don’t forget however, to get performance like this out of it you’ll need a powerful fan or two. These can run $15-$20 each, depending on the model and manufacturer you go with.

If you’re looking for one of the best heatsinks on the market, this should be at or near the top of your list. From its great looks to its superb performance, Thermalright has gotten it right (heh) with the Venomous X!

Thanks very much to Thermalright for supplying this unit for review.

The heir to the famous Thermalright Ultra-120 eXtreme is not very different from its predecessor, but nevertheless, we managed to discover at least one significant distinguishing feature. Read more in our review.

I think it would be difficult to accuse Thermalright Inc. of being slow to the market with new cooling solutions. Strange as it might seem, but we should actually blame their competitors, who only last year managed to introduce products with similar or slightly better cooling efficiency than the solutions from Thermalright, which have been in the market since 2006-2007. The leadership of Thermalright Ultra-120 eXtreme was undeniable and indisputable until solutions like Scythe Mugen 2, ThermoLab BARAM or Prolimathech Megahalems came out, and Thermalright IFX-14 managed to keep the performance crown until the end of 2009. That could be the reason why the company didn’t pay too much attention to developing new cooling systems: they had stable revenue coming in anyway.

However, everything comes to an end one day. And so did the sole leadership of Thermalright coolers. Noctua NH-D14 and Cogage Arrow came out and appeared more efficient than Thermalright IFX-14. As for Thermalright Ultra-120 eXtreme, its position has been threatened by at least a dozen cooling solutions from different makers over the past year. Unwilling to put up with this situation, Thermalright undertook a counterattack starting with the launch of the recently reviewed new revision of Ultra-120 eXTreme. The second cooler that should help Thermalright get their leadership back is the main hero of our today’s article – Venomous X. The company is also rumored to be working on a new successor to their IFX-14, but that will be a different story. In the meanwhile, let’s see what the new Venomous X looks like.

Contents

Package and Accessories

The new cooler comes in a compact cardboard box colored mostly black:

Now Thermalright packaging looks much more interesting than the brown boxes they used to have, although there is still very little information on the packaging. Inside this box we find another one, a small flat box with accessories. The heatsink sits inside a polyurethane foam casing beneath the accessories box.

Like most coolers from this manufacturer, Thermalright Venomous X ships without a fan, but all the other accessories are in place:

Among them we get retention kit for LGA775/1156/1366 mainboards, installation instructions, four wire clips and four silicone strips for the fans, Thermalright The ChillFactor 2 thermal paste and a company logo sticker.

Venomous X is made in Taiwan and its MSRP is set at $65.

Design and Functionality

When you see Venomous X for the first time, it immediately reminds you of Thermalright Ultra-120 eXtreme. True, Venomous X heatsink is barely different from that of the predecessor.

The new heatsink is 5 mm shorter and 1 mm smaller: now it measures 127 x 63 x 160 mm and weighs 755 g instead of 790 g by Ultra-120 eXtreme. The cooler is still composed of six copper nickel-plated heatpipes 6 mm in diameter that hold aluminum heatsink plates.

Venomous X has 1 plate less compared with Thermalright Ultra-120 eXtreme rev.C. The gap between the plates is a little smaller than by Thermalright Ultra-120 eXtreme rev.C (1.9 mm vs 2.0 mm), but still a little bigger than by the old Thermalright Ultra-120 eXtreme, which plates were spaced out at 1.8 mm from one another. The plates are 0.5 mm thick.

Although the heatsink of Venomous X cooler is shorter and have one plate less, its effective surface area has hardly been affected, because it is of almost rectangular shape, while the Ultra-120 eXtreme heatsink was curved inwards. The heatpipes inside the heatsink are shifted in a little different way than by Ultra-120 eXtreme. The latter had its heatpipes arranged in an oval-shaped pattern. The new Venomous X cooler has its heatpipes lined up in two precise rows (three in each) that are shifted away from one another.

The heatpipes and heatsink plates are soldered together. The heatpipes are also soldered to the grooves in the cooler base plate. The thinnest part of the base plate below the heatpipe measures 2 mm.

The base of the new Venomous X is finished in a completely uncommon way for the solutions from this maker: it is polished to mirror shine.

However, the evenness is still the same – with a bump in the center – which is a typical distinguishing feature of all Thermalright coolers.

As a result, the imprint of the processor heat-spreader on the cooler base shows a clear emphasis on the central part.

Although Thermalright have been constantly protecting this bump claiming it is a “constructive peculiarity” of their cooling solutions, we still believe that ideally even base surface is way more efficient than the mirror-shining finish. Unless the heat-spreader of your CPU has a concavity in the center shaped exactly as the bump on the base of your cooler.

Compatibility and Installation Tips

Thermalright Venomous X in its standard configuration is positioned for Intel LGA775/1156/1366 processors. However, it is also possible to install this cooler onto AMD mainboards. In this case you will need to purchase an additional retention kit. Venomous X step-by-step installation is described on a separate page of the official company web-site. Besides, you can also download a PDF file with it. We also decided to check out the main installation steps, especially since in our opinion it is the key peculiarity of the new Venomous X cooler.

So, at first you have to take a universal backplate and insert the threaded retention spindles into the loops on its ends. You must use special plastic clips: just put them over the spindles and insert in one of the three locking holes in each corner of the backplate.

I believe that you have already understood that each of these holes is designed to match LGA775, LGA1156 or LGA1366 socket. This is what the assembled backplate looks like.

The thumb-screw on the right with a spindle on one end and a silicone washer on the other should be used to tighten up the retention plate.

After that you place the steel retention frame over the spindles and tighten the thumb-screws. There are four mounts coming out of the frame that will hold the retention plate pressing the cooler against the mainboard and processor. Note that there are four of them, which means that you will be able to turn the cooler any way you want without removing the retention frame and backplate. Now all you need to do is apply a very thin layer of high-quality thermal compound onto the CPU heat-spreader, push the retention plate between the cooler heatpipes and tighten the spring-screws with a screw-driver or enclosed wrench.

But that’s not all yet. This when the most interesting things begin. There is a large knob in the center of the retention plate that serves to adjust the pressure between the cooer base and the processor heat-spreader.

By turning this knob clockwise with the included wrench you can increase the pressure from 40 lbs (18.144 kg) to 70 lbs (31.752 kg). According to Thermalright engineers, this feature improved heat transfer and processor cooling efficiency. I have to admit that it is a pretty interesting and unique solution that we haven’t yet seen in any other CPU cooling systems. I would also like to add that when you are tightening this pressure knob the cooler retention panel is lifted up above the base that is why the cooler may actually turn on the processor. To avoid it, please make sure to hold Venomous X when tightening the pressure knob.

The final touch in the Thermalright Venomous X installation procedure is fans installation. You can attach one or two fans using the four silicone strips and four wire clips included with the cooler.

Thermalright recommends installing Venomous X in such a way that the airflow could be directed towards the back of the system case (perpendicular to the PCI-E slots).

It contradicts our theoretical assumptions that the preferable cooler positioning would be with the heatpipes going along the LGA1366 processor die. That is why before we proceeded with the cooler efficiency tests, we checked out its performance in two different installation positions.

Although in the first case (as shown on the left) the heatpipes were directed along the processor die, which is considered less effective position, Thermalright Venomous X performed 2°C better than if installed as shown on the right. During our comparative tests we checked the performance of Venomous X equipped with one fan rotating at 1200 RPM and with the case fan disconnected.

Technical Specifications and Recommended Pricing

We are going to compare the technical specifications of Thermalright Venomous X side by side with those of its predecessor, Thermalright Ultra-120 eXtreme rev.C.

The testbed and methodology applied in this case was exactly the same as the testbed and methodology described in our previous article about tuned up CPU coolers that is why we are going to skip this section and proceed right to the test results. Besides Thermalright Ultra-120 eXtreme rev.C, we also added the results of Cogage Arrow and Noctua NH-D14 for comparative purposes.

Cooling Efficiency Tests

First of all we have to say a few words about the effect of the new retention mechanism on the cooling efficiency. Unfortunately, the most interesting design innovation of the new Thermalright Venomous X produced the least interesting results. Namely, tightening the knob that increases the pressure by 75% doesn’t have any influence on the cooler performance. Moreover, the peak CPU temperature doesn’t drop with any of the two tested coolers: Thermalright Venomous X as well as Thermalright Ultra-120 eXtreme, which we also tested with the new retention kit. It is hard to explain why both coolers proved so indifferent to the new enhanced retention mechanism. Maybe the bump in the center of the cooler base ruins the engineers’ efforts, and maybe the increased pressure is simply the wrong approach to improving the cooling of LGA1366 processors with the largest contact spot between the cooler base and the CPU die. Hopefully, you will have better luck. As for us, we would like to move on to the actual efficiency tests.

Before we compare Thermalright Venomous X against its competitors, let’s check out the dependence of its cooling efficiency on the number of cooling fans and their rotation speeds.

Obviously, the cooling efficiency of Venomous X increases most significantly in the 600-1000 RPM fan rotation speed range, where peak CPU temperature lowers on average by 10°C with one fan and by 7°C with two fans installed for air intake/exhaust. You can win a few more degrees by speeding up the fan(s) to 1200 RPM, while further increase in fan rotation speed doesn’t lower the CPU temperature that much anymore. For example, in the 1200-2000 RPM range the peak CPU temperature will only get 2°C lower. This way we can conclude that Thermalright Venomous X heatsink doesn’t really need high-speed fans. At the same time, those users who appreciate quite system operation and consider an 800 RPM fan to be as loud as they are willing to go, could use Venomous X with two fans.

Finally, here is the diagram comparing the results of our today’s hero, Thermalright Venomous X, against three best coolers from the previous test session.

Only in one test mode out of six Venomous X yielded 1°C to Ultra-120 eXtreme, while in all other modes it outperformed its predecessor having caught up with Cogage Arrow and Noctua NH-D14. We may have expected a little more from Venomous X, but it didn’t go through. Despite this fact, the new cooler is still one of the best CPU air coolers.

In conclusion let’s check how far we could overclock our test processor using Venomous X with two cooling fans in two speed modes: at 800 RPM and at 1600 RPM. For the same of comparison I will also provide the results obtained with Thermalright Ultra-120 eXtreme rev.C.

In quiet mode Ultra-120 eXtreme rev.C turned out a little better, while at 1600 RPM Venomous X takes revenge leaving its predecessor a little behind. I have to say that the results demonstrated by both coolers are very close, so we can’t declare any of them an ultimate winner at this point.

Conclusion

It looks like we can once more time conclude our review with a phrase that there is yet another super-cooler out there right now, but for some reason we are not particularly excited. Over the past year and a half we have witnessed very moderate and slow evolution of the CPU air cooling systems. That must be the reason why we are not raving with optimism just yet. I wish that Moore’s Law worked for cooling systems, too, so that we could finally see a significant improvement in cooling efficiency.

Yes, Thermalright Venomous X is an excellent cooler with remarkable efficiency. It is a little expensive, but the fans of Thermalright brand will not be discouraged by a 65-dollar price tag. New retention mechanism and mirror-shining base surface are good bonuses, but unfortunately, they do not produce the desired effect. At the same time, we don’t quite understand why Thermalright engineers didn’t perforate the heatsink plates of Venomous X the same way they did with the pates of Ultra-120 eXtreme rev.C, and why they didn’t make the cooler wider (83 mm instead of 63 mm). Even with two 120×25 mm fans the cooler would still be only 135 mm wide and would definitely stay below 900 g. Both these parameters are quite typical of contemporary CPU cooling solutions, but these measures could have increased the effective cooling surface by 32%, which would positively affect the efficiency. I don’t know if Thermalright engineers are thinking about it at all, but I am sure they could have checked it out, just out of curiosity.

Thermalright Venomous X Silent Edition CPU Cooler

The Venomous X Silent Edition is a combination of a potent Thermalright heatsink and a pair of extremely low speed fans. Though not completely “silent,” it is probably the quietest actively-cooled CPU heatsink available.

Thermalright

Street Price

US$70~$75

We’ve encountered many PC products over the years that have been described by its manufacturer as “silent” but as silence is defined as the complete lack of noise, most inevitably fall well short of the promise. Once you see a fan, at best it can be described as is “inaudible” or varying degrees of “quiet.” Present us with a “Silent Edition” CPU cooler with not one, but two fans, and we could suffer from a vertigo attack from the amount of eye-rolling required. That being said, Thermalright’s Venomous X Silent Edition might just have what it takes to be the quietest and most effective CPU heatsink to make this claim.


The package.

It is unclear how the retail version of the Silent Edition will be packaged. Though sold as a single unit, our sample arrived at our door in separate pieces, one unusually decorative box for the heatsink, one box for each 600 RPM fan just as they are sold in retail channels, and even individual cardboard containers for two plastic fan holders. The fan cages seem to a redundant inclusion as the heatsink ships with the traditional metal clips as well, which are superior in that they allow the use of 14 cm fans (provided they have 12 cm mounting holes). The Silent Edition also ships with a 4-pin PWM fan splitter cable to run both fans off the same header, though they are 3-pin models and thus lack PWM support.


Original Ultra-120 eXtreme on top, Venomous X on the bottom.

The Venomous X is not a new heatsink, having been made available in several forms for over a year. If you’re not familiar with it, it is very similar to the Ultra-120 eXtreme in design and composition. The overall dimensions are almost identical though the eXtreme is 5 mm wider as the center portion of the heatsink juts outward slightly. The shape of the fins on the Venomous X are also more stylized and its heatpipes are arranged in a different pattern.


Ultra-120 eXtreme on the left, Venomous X on the right.

The Venomous X also appears to have a larger fin-stack, but the total surface area is about the same. The spacing between the fins is wider than the eXtreme, which should improve performance with low speed fans like the 600 RPM models included with the Silent Edition. In addition there are twice as many of the small tabs on each fin that provide stability and ensure equal spacing.

Feature & Brief

Our Comment

Patented multiple support pressure vault bracket system, allow users adding pressure to the bracket system (40~70 lbs. pressure system for Intel CPU user only), and have a more efficient and secure mounting. The mounting system is critical for a heatsink’s performance.
Include AMD Socket AM2/AM3 Bracket system. Sometimes omitted on CPU coolers.
Mirrored copper base increasingly upgrade the quality and the performance of the heatsink. The base surface doesn’t need to be polished perfectly to perform well, but it’s a nice visual.
Special bent winglet design, allows hot air to pass the heatsink more rapidly. A design element that debuted in the original Ultra-120.
Heatsink are all nickel plated to ensure the best quality and performance and could last for years. Most high end heatsinks are nickel plated to prevent oxidation.
Soldered heatpipes, copper base and fins, to ensure the best thermal conducting efficiency. Solder helps transfer heat between the various components of the cooler.
Six sintered heatpipe design, all heatpipes are nickel plated.To slow the oxidation deterioration to the heatpipe, to ensure longer usage and performance of the heatsink for the cpu. Just like the Ultra-120 eXtreme, the Venomous X sports six heatpipes.
Including FDB 600RPM ultra low noise Fan Cover set*2 and Chill factor III thermal paste. At 600 RPM, the included fans should be close to silent.
Convex copper base design, to ensure the Highest thermal conducting thermal efficiency between the CPU and the heatsink. Like previous Thermalright heatsinks, the base is slightly convex to achieve greater contact with the center of the CPU.

PHYSICAL DETAILS & INSTALLATION

The Thermalright Venomous X Silent Edition is composed of a copper base, 6 x 6 mm thick copper heatpipes soldered to 47 aluminum fins, and the entire body is also nickel-plated. By our measurements, the heatsink weighs approximately 780 grams and stands 161 mm tall. The included mounting system is the same employed by the Thermalright Silver Arrow. The installation procedure is detailed here.


On average the fins are 0.53 mm thick and spaced 1.84 mm apart, an increase of more than 20% compared to the various editions of the Ultra-120 eXtreme.


Viewed from another angle.


The base of the Venomous X is convex and has a nice shine which is absent from some of Thermalright’s older coolers.


The mounting system employed is similar to that used by Prolimatech. Simple but effective, it features a bar at the center that exerts considerable pressure on the base.


Installed on our test motherboard with a pair of Nexus 120 mm fans. Note that if you use the wire clips, they should be installed before mounting the heatsink. The hooks are unusually long and may interfere with northbridge and VRM heatsinks.

Measurement and Analysis Tools

  • Extech 380803 AC power analyzer / data logger for measuring AC system
    power.
  • Custom-built, four-channel variable DC power supply, used to regulate
    the fan speed during the test.
  • PC-based spectrum analyzer:
    SpectraPlus with ACO Pacific mic and M-Audio digital
    audio interfaces.
  • Anechoic chamber
    with ambient level of 11 dBA or lower
  • Various other tools for testing fans, as documented in our
    standard fan testing methodology
    .
  • SpeedFan,
    used to monitor the on-chip thermal sensors. The sensors are not calibrated,
    so results are not universally applicable. The hottest core reading is used.
  • Prime95,
    used to stress the LGA1366 CPU heavily, generating more heat than most real applications.
    8 instances are used to ensure that all 4 cores (with Hyper-threading) are
    stressed.
  • CPU Burn,
    used to stress the AM3 CPU heavily, generating more heat than most real applications.
    4 instances are used to ensure that all 4 cores are
    stressed.
  • CPU-Z,
    used to monitor the CPU speed to determine when overheating occurs.
  • Thermometers to measure the air temperature around the test platform
    and near the intake of the heatsink fan.

Noise measurements are made with the fans powered from the lab’s variable DC
power supply while the rest of the system was off to ensure that system noise
did not skew the measurements.

Load testing was accomplished using Prime95 or CPUBurn to stress the processor, and the
graph function in SpeedFan was used to ensure that the load temperature is stable
for at least ten minutes. The temperature recorded is the highest single core
reading. The stock fans were tested at various voltages to represent a good
cross-section of airflow and noise performance.

The ambient conditions during testing were 10~11 dBA and 21~23°C.

Stock Fan Measurements

The fans included with the Venomous X Silent Edition use fluid bearings and spin at just 600 RPM. They have a standard seven blade design with gentle curves and straight struts. They weight about 160 grams, which is 40 grams more than most 12 cm models. Much of the extra weight is probably due to the motor as the hub measures an unusually wide 47 mm across.

As for the noise level of the fan, it’s almost nonexistent. When mounted on the heatsink, It produces a slight hum at close proximity but is completely inaudible at one meter’s distance, even at full speed. It barely registered on our sound meter, measuring about half a decibel more than our anechoic chamber’s noise floor. This is about as close to silent as it gets, and undervolting it is pointless unless the fan is going to reside right next to your ear.

With a single stock fan, the Venomous X was a mediocre performer with a thermal rise of 47°C, however this was an impressive result as it was inaudible. Adding the second fan improved cooling by 5°C while barely affecting the overall noise level. Doubling up the stock fans gave us slightly better acoustics and temperatures than our reference Nexus 120 mm fan running at 7V. This too was commendable as the Nexus is the best performing fan we’ve come across.

Using two reference fans resulted in only a 2~3°C improvement but also on emitted 1 dB more using the stock fans, so it’s not a conclusive which combination is superior. Our reference Noctua 140 mm fans actually performed slightly worse, allowing the processor to heat up about 2~3°C more than the Nexus fans at comparable noise levels.

MP3 SOUND RECORDINGS

These recordings were made with a high
resolution, lab quality, digital recording system
inside SPCR’s
own 11 dBA ambient anechoic chamber
, then converted to LAME 128kbps
encoded MP3s. We’ve listened long and hard to ensure there is no audible degradation
from the original WAV files to these MP3s. They represent a quick snapshot of
what we heard during the review.

These recordings are intended to give you an idea of how the product sounds
in actual use — one meter is a reasonable typical distance between a computer
or computer component and your ear. The recording contains stretches of ambient
noise that you can use to judge the relative loudness of the subject. Be aware
that very quiet subjects may not be audible — if we couldn’t hear it from
one meter, chances are we couldn’t record it either!

The recording starts with 5~10 second segments of room ambiance, then the fan
at various levels. For the most realistic results, set the volume so that
the starting ambient level is just barely audible, then don’t change the volume
setting again.

FINAL THOUGHTS

Though obviously unable to live up to its “silent” billing, the Thermalright Venomous X Silent Edition comes as close as an CPU heatsink can to this claim without resorting to passive cooling. As the included fans spin at a meager 600 RPM and employ fluid bearings, they are exceedingly quiet, being effectively inaudible even in our anechoic chamber. They also perform surprisingly well on the Venomous X, giving our reference Nexus 120 mm fans a run for their money. We aren’t big proponents of the plastic fan mounts though — the metal clips work just as well and as a bonus, are compatible with most 14 cm fan models. The heatsink itself, being built from the same mold as the Ultra-120 series, has the same superb cooling proficiency as the Ultra-120 eXtreme Rev. C, thanks in no small part to its convex base and sublime mounting system.

If you’re in the market for a potent CPU cooler that is extremely quiet straight out of the box, the Venomous X Silent Edition fits the bill better than any product we’ve tested in recent memory. Our only complaint is the current street price of US$70~$75. Larger, more capable coolers like the Thermalright Silver Arrow and Noctua NH-C14 can be found for about the same amount, though they both require some fan control magic to match the noise output of the Silent Edition. This isn’t necessarily a bad thing as their higher fan speeds also make them more versatile — an 11 dBA cooler afterall is beyond overkill for many users.

Our thanks to Thermalright for the Venomous X Silent Edition heatsink sample.

Thermalright Venomous-X The Empire Strikes Back

There is an uncanny resemblance between the Venomous-X and Ultra eXtreme. There are, though subtle difference between the two. They are designed to make the Venomous-X a meaner, sleeker and light weight, with sacrificing performance. The venomous-x is shorter (5 mm), barely smaller (1mm) and lighter (755 grams instead of 790 grams) as compared to its predecessor. The cooler still has 6 heat pipes which are 6 mm in diameter. (For a list of differences please refer to the table at the end of the section)

The Cooling Tower –Sleeker

The cooling tower is designed pretty much like that of a TRUE, though there are some differences as compared to the latest incarnation of the latter (rev C).

The plates in venomous-x are spaced about 1. 9 mm apart. (As compared to 2.0 mm for rev C) and there is one less plate to boot (47 vs 48).

Despite the lack of one plate and the smaller dimension of the cooler, the cooling area is almost the same as that of rev C. This is because the plates are almost rectangular, while rev C. had its plates curved inward at the center (i.e. concave outwards). The total cooling area is about 3525 cm2. The smaller gap helps improve air pressure, while the change in shape allows for a smaller design with a similar heat dissipation surface as the rev C.

The plates are also constructed differently. The cooling plate’s edge design has been changed. From a concave (outward) flat surfaced plate design to a serrated design. This has been seen before in Noctua’s NH-D14, but here the serrations are wider and quantitatively less. These are designed to help reduce resistance to air flow.

The plates still have the same bent design in a profile view. This helps direct airflow towards some of the voltage regulatory circuit.

What is missing from the cooling tower (that was present in TRUE rev C) is a central perforation (cut out) at the bottom which ran through the length of the cooler

The Heat Pipes

The cooler sports 6 Nickel plated copper heat pipes of 6mm diameter –exactly like the previous TRUE models. However they do have a different orientation within the heat sink. They are arranged in two straight rows, rather than an oval (see picture above). This is done (presumably) to improve airflow and heat dissipation. The heat pipes are soldered to the plates as well as the heat sink base. The solders are all clean and there isn’t any excess solder on any of the joints.

The Heat Sink Base –Shiny!

A definite departure from all prior thermalright cooler design is the presence of a mirror shine base. Testing in the past has revealed that the shiny or matte finish of the base has minimal if any impact on cooling performance. Nonetheless the presence of a shiny base is something that did take me by surprise simply because Thermalright has never done anything like this before!

The center of the base has a forward convexity –standard Thermalright design characteristic. According to their engineers this is the best way to ensure the highest thermal conducting thermal efficiency between the CPU and the heat sink. I suppose with the inclusion of a variable pressure knob, the convexity can eventually be flattened somewhat, so there might be some logic to this design.

Impressions

As always the construction of the cooler is top notch. The heat pipes are soldered to the plates in the cooling tower. The solder points are not apparent, the base (surprise, surprise) has a mirror shine. The cooler’s uncanny resemblance to the rev. C is a testament to the engineers at Thermalright. They are confident enough to model their latest cooler so close to its predecessor, showing how well designed it was. Thermalright had the (almost) perfect single tower design with the TRUE. What they have done is taken a winning design, modified to make it “sleeker” (read: smaller and light weight) and more aerodynamic (better airflow) and thermally advantageous (read more heat dissipation). Where other companies have drastically altered their design in order to improve cooling (e.g. Noctua moving to a two tower design) and dethrone Thermalright, they (Thermalright) have decided to improve upon their single tower design, rather than work on a two tower cooler (ala IFX-4) first. I say first as it is rumored that Thermalright might be working on a new dual tower design.

The inclusion of a variable pressure knob is a new feature. What remains to be seen is its utility in actual cooling. This will become clear after testing.

Apart from the lack of fans (and perhaps a mounting system for AMD platform) in the box, I really can’t fault the package. Everything is built to (high) Thermalright standards.

Here is a table showing how the Venomous-X differs from TRUE Rev C.

Thermalright Venomous X Retail Incl. Fan and Fan holder — tHe_BiNk — Userreviews

Oude Situatie

Ik heb een Gigabyte EP-45-DS4 moederbord, daar zat in eerste instantie een Intel C2D E8400 op die was overklokt naar 3. 6GHz. Ik gebruikte een Scythe Ninja Rev. B CPU-koeler (kosten 35 euro incl. fan) om deze te koelen, en had daar nooit problemen mee. Op de CPU-koeler zit een 1200 RPM fan van Scythe, deze is lekker stil, en wil ik blijven gebruiken.

Nieuwe Situatie

Ik heb mijn C2D vervangen door een Intel Quad Core Q9550. Voornamelijk omdat ik mijn videokaart een MSI nVidia 7900 GTO had vervangen door een Powercolor Radeon 5850, en de CPU nu eerder een beperkende factor is tijdens gamen (op 2560×1600). Of het echt nodig was, weet ik niet. Maar het kan, en dus moet, het altijd sneller. Zie ook mijn review van twee Intel SSD’s in RAID0. http://tweakers.net/produ…ssdsa2mh080g2c1-80gb.html

Case: Cooler Master CM Stacker 810

Link naar volledige specs http://tweakers.net/gallery/sys/6787

Het Probleem

Toen ik de Q9550 kreeg heb ik deze gelijk overklokt naar 3.4GHz en heb er verder eigenlijk niks meer aan gedaan. Snel zat, voor normaal dagelijks gebruik. Echter tot mijn verbazing kon ik de bus van de CPU verhogen naar 460 zonder het voltage te verhogen, wat 3.9GHz oplevert. En dan moet je toch wel proberen om de 4GHz te halen! Echter was het probleem dat de oude koeler de warmte niet kon afvoeren. Na 10-20 minuten OCCT resette de computer zich steeds.

De nieuwe koeler

Deze moest de beste zijn, maar niet tegen elke prijs. Ook wilde ik graag dat deze koeler geschikt was voor socket 1156 en 1366. Het is uiteindelijk de Thermalright Venomous X geworden. Dit is de ‘opvolger’ van de welbekende Thermalright Ultra 120 die we in vele varianten kennen. Deze staat bekend dat het 1 van de beste, zo niet beste, CPU-koeler die er is. De reviews (zie einde review) waren echter allemaal ook positief over de Venomous X, echter was de meerprijs tov de Ultra 120 niet te rechtvaardigen. Echter is de Venomous X nu niet veel duurder dan de Ultra 120. De koeler kost 48 euro, daar kan je een leuke AMD dualcore CPU incl. standaard koeler voor kopen, maar de prijs was voor mij nog net acceptabel. Je hobby kost nu eenmaal soms wat geld. Let op, er zit GEEN fan bij.

Convex copper base design, to ensure the Highest thermal conducting thermal efficiency between the cpu and the heatsink.

Er zitten vier rubberen strips bij tegen vibraties voor de twee te monteren fans. Ook zitten er vier klips bij om de twee fans te kunnen bevestigen.

De bevestiging

De oude CPU-koeler de Scythe Ninja gebruikt plastic push-pins. Hoewel ik de CPU-koeler enkele malen heb gemonteerd en gedemonteerd, zonder dat het bevestigingssysteem het begaf, blijf het plastic. Je moet voorzichtig zijn dat je de uiteindes van de plastic pinnen niet afbreekt.

Gelukkig is de bevestiging van de Venomous X geheel van, ongeveer 1mm dik, metaal. Dit voelt echt super sterk (en zwaar) aan, en is het beste bevestigingssysteem wat is tot nu toe heb gebruikt. Het is snel en gemakkelijk aan te brengen. Helaas moest het moederbord wel uit de kast om de backplate te bevestigen. Maar dit komt omdat mijn kast geen gat achter het moederbord heeft.

De test

De idle temperaturen met de oude CPU-koeler de Scythe Ninja waren (gemeten met CoreTemp 0.99.6):

Core0 – Core1 – Core2 – Core3

37C – 36C – 36C – 35C

De oude CPU-koeler de Scythe Ninja kon de Quad Q9550 niet koelen bij volle belasting, met een reset van de computer tot gevolg. De temperatuur was.

Core0 – Core1 – Core2 – Core3

72C – 65C – 63C – 63C

De idle temperaturen met de nieuwe CPU-koeler zijn:

Core0 – Core1 – Core2 – Core3

37C – 36C – 32C – 32C

De temperaturen met de nieuwe CPU-koeler zijn onder volledige belasting met OCCT zijn:

Core0 – Core1 – Core2 – Core3

53C – 49C – 47C – 47C

De temperatuur is met 16 tot 19 graden gedaald, bij volledige belasting van de CPU. Een zeer goed resultaat zou ik zeggen. Ook zijn de resets verdwenen. De kamertemperatuur was ongeveer 19 graden.

Hieronder zie je de temperaturen van core 0 tijdens 10 minuten OCCT. Eerst de resultaten van de oude koeler en daarna de nieuwe Venomous X. Je ziet duidelijk dat de temperatuur behoorlijk is verbeterd, en dat de Venomous geen problemen heeft met het afvoeren van de warmte. De CPU fan is gelijk gebleven de stille 1200 RPM Scythe.

Ik zal later nog toevoegen wat de maximale overklok is die ik heb behaald, en de bijbehorende temperaturen.

Conclusie

Duur, maar levert zeer goede koelprestaties. Gemakkelijk en snel in te bouwen, door het uitstekende bevestigingssysteem. Heb je 50 euro voor een koeler over, dan kan je eigenlijk niks beters vinden.

Positieve Eigenschappen

— ‘Beste’ luchtkoeler

— Geweldig sterke bevestiging op moederbord

  • Conclusion

Perhaps there is no more conservative manufacturer on the air cooling market than Thermalright. They release new products extremely reluctantly. And although the company has existed for many years, really different Thermalright processor heatsinks can be counted almost on the fingers. Perhaps that is why each new product of this manufacturer is very likely to become a «cult». And let the old ones have long been inferior to competitors in terms of efficiency, and all the latter suffer from the “crooked foundation” disease. Most overclockers don’t care. The Thermalright logo in the system unit of their computer is a sign of «involvement» … even if it’s not very clear why :).


Thermalright Ultra-120 eXtreme

Take the Ultra-120 eXtreme processor heat sink. That’s what it’s called now. A few years ago there was an Ultra-120 «just» on four heat pipes. He acquired the eXtreme suffix along with their third pair. And by the beginning of 2010, the Ultra-120 eXtreme managed to upgrade to the third revision (“C”), get a variant in “fashionable” black and even a limited edition all-copper version.

9The 0026 Ultra-120 eXtreme has long been the flagship of the Thermalright line. Until in 2007, the manufacturer did not announce its successor — the «monster» Thermalright IFX-14. This tower heatsink has set a new benchmark in CPU air cooler performance. Two packs of fins evenly strung on four 8mm heat pipes, a huge finning area and high-quality thermal contact at all «junctions» in the heatsink itself — that’s what made it a benchmark for other manufacturers of processor cooling systems for a long time.

And they, albeit slowly but surely, pulled themselves up. There were also outright clones, like Asus Triton 88. But why suddenly clones? Isn’t the Thermalright IFX-14 itself a development of an idea proposed by Sunbeam with its Tuniq Tower cooler? We can also mention here the Cooler Master V10 — a very interesting cooler, but it is extremely difficult for it to reveal its undoubted potential in real conditions. Monsters from Scythe flashed at exhibitions, but did not go into the series. However, after Orochi — no wonder. As a result, comparable efficiency (and according to some reports, it even slightly outperforms the IFX-14) was only recently achieved by Noctua with its NH-D14 cooler.

Thermalright didn’t wait for a sequel and just released their new heatsink. True, surprisingly, it did not become an evolutionary development of the IFX-14. It didn’t even become revolutionary.

recommendations

Venomous-X is more likely to replace the «old man» Ultra-120 eXtreme: the same form factor, the same six 6 mm heat pipes, even the bend of the fins is the same. And the recommended price set by the manufacturer at $ 65 is clearly lower than that for the IFX-14. However, according to some reports, the heir to «i-f-x» is also not long to wait. In the meantime, the «general» will still have to «fight», the modernization began with the «middle command staff».


Thermalright Venoumous-X

By the way, the Thermalright Ultra-120 eXtreme will certainly not disappear anywhere. In the worst case, he, having fallen a little in price and having lost nickel plating, will continue to be produced under the Cogage trademark.

But how good is the «replacement» in the face of Venomous-X, we’ll find out today. But not only. It is necessary to clearly understand what place the new product occupies in the Thermalright lineup. Price positioning is one thing. But the actual cooling efficiency is quite different. Therefore, both closest “comrades” became his rivals in the test: Ultra-120 eXtreme and IFX-14.

However, first things first. For now, let’s take a look at the «hero of the occasion.»

The Thermalright Venomous-X came to the overclockers.ru laboratory in a fairly shabby cardboard box.


But it will be sold in a completely different place — it was found inside. And next to it is a 120 mm fan, also under the Thermalright brand.

Something in this world is still changing. Many users liked the strict Thermalright boxes: high-quality cardboard in a standard beige color, a modest model name — nothing superfluous, but very solid. Therefore, when some time ago they were replaced by a typical gloss, … it was sad ©. In the case of Venomous-X, a cautious and, perhaps, the right step back is clearly visible. A strict black box does not look so bad. Only its front part is somehow decorated (the name of the model, by the way, shimmers with poisonous flowers *). It is strange that there was no room at the back even for a short list of technical characteristics.

* No wonder “venomous” (English) is poisonous, vicious.

But let’s continue unpacking the cooler. At first it seems that inside the «matryoshka» continues. But no, this is a thin box with accessories. And below, surrounded by polyurethane foam, the radiator itself is located in the package.

Thermalright Venomous-X only comes with a bracket for Intel processor sockets: LGA 775, 1156 and 1366. A kit for fans of the AMD platform has not yet been announced. But a separate mount for Socket AM2 / 3 in the manufacturer’s assortment
present
.

In addition to the above bracket, the Venomous-X accessory box contained:

  • four fan brackets,
  • four self-adhesive elastic strips for fans,
  • tube of Thermalright Chill Factor 2,

  • pressure wrench,
  • Large body sticker with Thermalright and
  • branding

  • a pair of sheets containing installation instructions and a list of the contents of the box.

Fans not included with Thermalright Venomous-X.
