SilentiumPC Grandis XE1236 — Test and Review —

SilentiumPC Grandis XE1236 is the newest and actually the first CPU cooler in the portfolio of the relatively new Polish company SilentiumPC designed as a twin tower cooler structure to provide the best possible cooling performance and noise level balance. Grandis XE1236 itself is made to deliver very serious heat dissipation service and of course the XE Technology. And last but not least, let’s not forget a very good and stylish appearance.

I already have the cooler ready to be tested and reviewed and to be honest I am really excited to check what this product has to offer while cooling my AMD FX-8350 processor at default, a bit overclocked and a bit more overclocked frequencies.

But of course, let’s first pay some attention to the box.

 Front side of the box  Back side of the box

 

SilentiumPC Grandis XE1236 arrived to me for a test and review using my power hungry and very hot processor,  in a pretty big and very stylish looking carton box. The package itself is painted in white, grey and light blue colours featuring a big picture of the cooler itself on the front panel of the box, while the full technical specifications and some additional details regarding the product are located on all sides of the package. And I should say there is plenty of interesting information in several languages.

Let’s put the box aside and check what is placed inside of it.

After I opened the top cover of the box, the first thing to notice was the very detailed installation leaflet, of course typical for all manufacturers on the market, the white box holding all of the additional accessories, and right beneath it there was the cooler packed in a very solid plastic package and the additional fan placed inside a second white carton box. WOW, this product has a second white box!

As always, let’s start checking what is inside the white box made to deliver the additional accessories.

 

SilentiumPC Grandis XE1236 ADDITIONAL ACCESSORIES

All of the additional accessories accompanying the cooler were delivered to me packed in separate nylon bags just to ensure that all of the parts will be in perfect condition and most of all in full quantity. After I took all of the additional accessories out of their packages and arranged them for making some shots, this is the view I got.

The standard SilentiumPC Grandis XE1236 accessories pack features:

  1. Solid metal back plate required for both Intel and AMD sockets
  2. 2 x long metal front brackets needed for installing the cooler on AMD sockets in horizontal position
  3. 2 x short metal front brackets needed for installing the cooler on AMD sockets in vertical position
  4. 2 x metal front brackets needed for installing the cooler on all Intel sockets in both horizontal and vertical positions
  5. 4 x additional metal clips for installing two additional 120mm fans
  6. A various set of bolts, screws and plastic washers needed for the AMD and Intel installations.
  7. A syringe of Pactum PT-1 thermal compound
  8. Y-pwm splitter for powering and regulating up to two fans.
  9. A metal wrench for fastening the nuts during the installation.
  10. Additional SilentiumPC GF12025 120mm fan
  11. Installation manual

In my experience and from what I saw previously with other CPU coolers of the brand, the additional accessories pack is rich enough to provide a lot of possibilities and to be compatible with all modern sockets and processors. Apart from that, all of the major installation accessories are actually made of solid metal, which will definitely deliver robust connection between the processor and the cooler and overall reliable cooling performance.

And it is time to make things more interesting and finally check the cooler’s structure.

 

SilentiumPC Grandis XE1236 HEAT SINK STRUCTURE

At first glance, SilentiumPC Grandis XE1236 offers a pretty standard for a twin tower cooler structure, featuring the three important components which I am going to check one by one in this review and they are: the heat sink formed as two thin and very stylish looking towers, the two 120mm fans doing the cooling magic and the most important one – the mounting kit.

As usual, let’s start with the heat sink.

SilentiumPC Grandis XE1236 offers a radiator structure made of copper/aluminum contact plate, 6 x Ø6mm copper heat pipes without direct contact with the processor, and of course aluminum fins grouped together forming the two-tower setup. The overall cooler dimensions are 130 x 105 x 158 mm and weight of 1160 g including the fans. Pretty serious dimensions, I should say.

First things first, so let’s start with the contact plate and the XE Technology.

SilentiumPC Grandis XE1236 features a perfectly milled contact surface designed according to the XE Technology and featuring two plates soldiered together and holding tight the copper heat-pipes for the best possible durability.

The top part is actually made of aluminum block, while the bottom part is made of a perfectly milled copper plate acting as a additional heat spreader that transfers the heat more efficiently from the CPU to all 6 x Ø6mm copper heat pipes symmetrically arranged according to the center of the contact plate and going through all of the aluminum fins on each tower.

The heat-pipes themselves are grouped in a very interesting way in 2 groups holding 3 pipes on the outer sides of each fin stack, which will deliver the best possible heat dissipation using the surface of the fins in the optimal way. The only thing that I would recommend for future models is to deliver heat pipes caps to improve the cooler’s appearance.

And since I started speaking about the fins, let’s pay some attention to the next part of the heatsink, which is actually the surface made for dispersing the heat – the fin stacks.

SilentiumPC Grandis XE1236 left side of the heat sink SilentiumPC Grandis XE1236 top/front side of the heat sink

 

SilentiumPC Grandis XE1236 offers an absolutely symmetrical  to the center of the contact plate and absolutely identical two towers with 46 x 1mm thick performance aluminum fins with 2mm fins gap. The top fin for both towers is 1mm think, entirely painted in black matte with the company logo to boost the overall appearance of the cooler.

Both of the fin stacks are not equipped with rubber dampers to reduce the vibrations of the fans, of course if there are any vibrations when the fans are installed and working.

The aluminum fin stacks, together with the heat pipes and the contact plate form a very massive and solid cooling radiator, which is capable of holding up to 3 x 120mm fans attached with metal fan clips for the best possible cooling performance.

And by saying fans, let’s talk about them.

The standard SilentiumPC Grandis XE1236 package includes two SilentiumPC GF12025 fans. Both of them have entirely painted in black matte 120 x 25mm square frames and painted in glossy black propellers with 7 very wide and not very sharply angled blades. The fans are designed to operate at 500 ~ 1500 +/-10% revolutions per minute range providing airflow level of 55.00 CFM at noise level range of 21dBA.

Before I continue with the tests, I will have to install the fans and prepare the cooler for installation on the motherboard.

To install the fans the only thing that I have to do is clip them to the two towers with the provided metal clips. Of course, the standard setup features 2 fans with 2 pairs of metal clips. Apart from that, the cooler is provided with a third pair of clips for installing a third fan.

And to be honest, 3 fans installed on this radiator will definitely deliver amazing performance but will block absolutely everything around the processor socket.

One fan installed Both fans installed

 

The power and the regulations of the fans is done by pretty long, entirely sleeved in black 4-pin PWM cables and connectors, and both of the fans should be connected directly to the motherboard CPU fan header using the provided in the package PWM Y-splitter, as you can see on the picture above.

All parts assembled together formed a very massive and very stylish CPU cooler which should require a very reliable and rigid mounting kit.

Of course, to test the cooler’s performance in real conditions I will have to install it on my motherboard with the provided mounting kit.

According to the official details provided on the company web page, the cooler uses the same backplate and is compatible with all modern sockets:

  1. Intel sockets:  LGA 775, LGA 1366, LGA 2011, LGA 1150, 1155, 1156
  2. AMD sockets: AM2(+), AMD AM3 (+), FM1, FM2, FM2+

Of course, for doing the tests I will use the AMD brackets and these are the parts needed so the cooler can be installed on the motherboard:

As always, the first thing to do is to get familiar with the installation manual, read the instructions carefully and pick up the right accessories for the actual socket… And later to prepare the mounting kit before attaching it to the motherboard.

For AMD sockets there are two ways to install the cooler.

The first way is to use the two shorter metal front plates which will deliver the option to install the cooler in vertical position or to use the 2 longer front plates, which will deliver the option to install the cooler in horizontal position. Of course, for my setup the best way is to install the cooler in vertical position for the best possible cooling performance.

All of the parts for the AMD socket Installed

 

Installing the mounting kit to the motherboard is actually a child play. Thank God I am still a kid, or at least this is the way I feel and it took me around a minute or less to install it to the motherboard. With the mounting kit installed it was time to apply some thermal compound, install the cooler and prepare if for the tests.

And this is what the cooler looks like installed on the motherboard:

Seen from the front
 Seen from the side

 

As you can see from the pictures above, when the heatsink is installed on the motherboard it is not possible for memories with taller heat spreaders to be used. After all, this is a really massive cooler which when installed is above the RAM slots and most of the elements around the socket.

And this is what the cooler looks like installed on the motherboard and inside the case.

The cooler itself definitely covers all the components around the socket and it perfectly fits in with the black interior.

 

SilentiumPC Grandis XE1236  TESTS

Since the cooler is installed I believe it is time to check my testing rig and continue the article with the tests…

CPU: AMD Vishera FX-8350

  1. At standard frequency 4.020 MHz (at 1.368V)
  2. At low overclock frequency of 4.220 MHz  (at 1.392V)
  3. At medium overclock frequency of 4.420 MHz (at 1.428V)

Case: SilverStone Raven RV-03

Power supply: Antec HCP-750W

Cooler: SilentiumPC Grandis XE1236

Thermal paste: Noctua NT-h2 thermal compound

For this test and review I am going to use the two standard SilentiumPC GF12025 fans working at full speed of around 1500 revolutions per minute, providing airflow level of 55CFM, at noise level of 21dBA in push-pull setup.

The tests will be conducted in a closed system with:

  1. 2 x SilverStone AP181 – 180mm fans on the bottom panel of the case putting fresh air in and spinning at about 1200 rpm
  2. 120mm fan behind the motherboard cooling the socket and spinning at about 1000 rpm.
  3. Room temperature of about 20 degrees.

Both SilverStone AP181 – 180mm fans were connected together to the chassis 1 connector and were rotating at maximum speed.

And here I want to describe my testing method.

I will install SilentiumPC Grandis XE1236 and do stress tests using Prime95 AVX software with constant load on the cooler for 14:30 minutes with custom settings of minimum FFT size (in K of 128), max FFT size (in K of 128) and Run FFTs in place at standard frequency of 4.020 GHz (at 1.368V), at low overclock frequency of 4.220 GHz (at 1.392V) and at medium overclock frequency of 4.420 GHz (at 1.428V) using the two fans working at full speed of 1500 revolutions per minute.

Now let’s check out the test results:

All of the test results have been summed up in the following charts:

And the fan speed during the tests:

With the test done and the results added to the article it is about time to share my thoughts regarding the product.

 

SilentiumPC Grandis XE1236 CONCLUSIONS

1. SilentiumPC Grandis XE1236 performance:

After I had some really nice time unpacking the SilentiumPC Grandis XE1236 and all of the pretty solid accessories, arranging them for taking some shots, installing the cooler on the motherboard and finally after I am done testing I can say that I am really impressed with the overall features and performance of the cooler.

As the first twin-tower cooler in the company portfolio, SilentiumPC Grandis XE1236 delivers pretty serious dimensions, very interesting and reliable contact plate structure, really solid installation, stylish appearance and most of all, serious cooling performance. And here I’d like to say: Good job, SilentiumPC!

The cooler itself is a massive structure made of copper and aluminum, made to deliver very good balance of cooling performance, while working at very low noise level, and it definitely does its job. According to what I saw during the tests, the cooler was working at somewhat higher temperatures because the fans were not able to deliver airflow and static level pressure which are strong enough, but they were pretty silent.

Moreover, after the tests the cooler was dropping the processor temperature pretty fast, which describes a very serious radiator heat conductivity. Something, which is very important.

After all of the tests I can say that this cooler will surely handle every processor working at standard or overclocked frequencies. Of course, for the ultimate performance 3rd SilentiumPC GF12025 fan will be required or a brand new set of faster, more powerful and much louder fans will be needed.

And since I started talking about the noise I want to share that throughout all of the tests, both of the fans were almost quiet. Yes, I was able to hear the noise from the air passing through the propellers but overall with my case closed the ambient noise level was pretty low.

 

2. SilentiumPC Grandis XE1236 appearance:

SilentiumPC Grandis XE1236 is made to deliver pretty serious performance and at the same time very stylish and clean design, which will definitely stay neutral when installed inside a modern middle or full ATX tower or a modding project with a black colour scheme. With its size the cooler somehow delivers the feeling of reliable performance and with the overall build quality, a long life span.

According to my review, I think that SilentiumPC Grandis XE1236 deserves the following reward:

Official price (MSRP) for SilentiumPC Grandis XE1236: 45€ incl. VAT

Official warranty: 24 months

I thank SilentiumPC for the test sample.

Users who follow the market of computer components have probably noticed the predominance of mainly Asian players on it. But companies with European roots, whose products are presented on the shelves of domestic stores, can be counted on the fingers of one hand. Therefore, it is very pleasant to see the desire of companies that are still little known in our area to promote their solutions in our market. After all, healthy competition among manufacturers is good for us, buyers.

The Polish company SilentiumPC, which has been successfully developing in its homeland and conquering the Western European market for 8 years, also does not mind diluting the shelves of domestic stores with its products. Moreover, the assortment itself and the approach of the manufacturer to the creation of products are worthy of special attention. In SilentiumPC, they relied on the most functional components with a good price-performance ratio. The latter is achieved by reducing the cost of the box and reducing the configuration to the minimum required. So the buyer does not overpay for components he does not need and expensive packaging, which, regardless of the colorful design, will end up in the far corner of the closet or pantry a few hours after the purchase.

At the moment, the manufacturer’s product range includes power supplies ranging from 500 to 700 W, cases of various sizes and form factors, laptop stands, fans ranging in size from 40 to 140 mm, as well as a variety of accessories. We had the honor to get acquainted with , a representative of the line of processor cooling systems, which currently includes 6 models, quite diverse in terms of size and cooling capabilities. We present to your attention the top cooler SilentiumPC Grandis XE1236 V2 .

The novelty is distinguished by a two-tower layout and the use of a pair of turntables in its design, a rather low rotation speed of which should provide excellent noise performance. Whether this is so, and whether the tested solution will be able to compete on an equal footing with models from more well-known manufacturers that have previously visited our test lab, we will definitely tell you further.

Packaging and contents

In addition to keeping the SilentiumPC Grandis XE1236 V2 cooler intact, the packaging also performs an excellent informational function. So, the front side allows you to find out the name of the manufacturer (SilentiumPC) and the cooler model (Grandis XE1236 V2), as well as get a first impression thanks to the image of the device printed here.

The sidewall shows us the cooler from different angles, at the same time providing a contact address for import and distribution in Poland, without hiding the fact that the device itself is made in China.

QR codes are placed on the back side to go to the manuals for installing the novelty on different platforms. The SilentiumPC Grandis XE1236 V2 package is also displayed here and its most remarkable features are described in three languages ​​(English, German and Polish):

  • mounting system ensures compatibility with a number of current platforms for AMD and Intel processors;
  • using a copper heat spreader and six U-shaped heat pipes with a diameter of 6 mm;
  • height of 158 mm makes the novelty compatible with most modern ATX cases;
  • use of two 120mm PWM controlled fans with the possibility of installing a third fan;
  • application of reinforcement plate;
  • Pactum PT-1 high performance thermal paste included.

    • In the same three languages, the second sidewall informs us about the characteristics of the novelty, including compatible platforms. In general, all the necessary data about the tested cooling system, including its appearance, can be gleaned from the package, which is very commendable. If SilentiumPC’s products officially appear on the markets of the CIS countries, then for sure all the information will be duplicated in Russian, so there will be no problems with understanding it.

    Accessories, like the side fan, are stored in a separate carton. The package itself is quite voluminous and contains everything you need to install the cooling system:

    • universal reinforcement plate;
    • four anti-vibration tips, studs and metal mounts for different platforms;
    • washer and standoff set;
    • set of brackets for fixing fans;
    • thermal paste in a syringe;
    • key;
    • adapter for connecting two fans to one connector;
    • installation guide.

    Note that the kit contains three pairs of brackets for mounting fans: we see two in the picture, and another one is attached to the internal fan, which was originally installed on the radiator. I would also like to draw your attention to the manufacturer’s concern for such details as a power adapter for fans and a key for easy installation. And, of course, there is a detailed installation guide, which will not be superfluous, given the rather extensive package.

    Appearance and design

    SilentiumPC Grandis XE1236 V2 consists of two tower sections based on six U-shaped copper heat pipes with a diameter of 6 mm. The radiator fins, made of aluminum, are 0.45 mm thick and are located relatively tightly: at a distance of 1.8 mm from each other. Therefore, their number is quite large: 47 on each of the towers. The manufacturer’s approach in this case is quite logical, because the more plates, the larger the heat transfer area, and hence the efficiency of the cooler.

    The tubes are arranged in a row, which is natural, given the small width of the radiator sections. The top plates are black, which goes well with the unpainted copper tube ends. The manufacturer’s logo is also present here, which does not allow confusing the novelty with solutions from other companies.

    Between the sections, access to the fixing plate, originally screwed to the base. It is secured with a single embossed head screw, which can be unscrewed with a long screwdriver (more than 150 mm long).

    The heatpipes in the SilentiumPC Grandis XE1236 V2 are not covered with a nickel layer, therefore, their surface is more prone to oxidation and some loss of thermal conductivity over time. The tubes themselves are soldered to the base, which will have a good effect on heat transfer, but the plates are strung on them without the use of solder.

    The base is also not plated with nickel. When polishing it, the manufacturer did not set himself the goal of obtaining a mirror reflection, but tried to ensure the most even surface, which he quite succeeded in. The dimensions of the base are 38 x 48 mm.

    For active heat dissipation from the radiator, two fans are used with the designation «Grandis XE1236», duplicating the name of the cooler. Judging by the information provided, these models are modifications of the Zephyr 120 PWM solution, featuring a higher maximum blade speed (1500 rpm instead of 1300 rpm). The novelties are based on hydrodynamic bearings, providing them with a long time between failures (50,000 hours).

    The propeller speed is controlled by PWM between 500 and 1500 rpm, so both fans are equipped with 4-pin connectors. The noise level at the same time remains quite comfortable and does not exceed 21 dB.

    Fans are fastened to the heatsink using supplied brackets. In the lower picture, you can see that due to excessive bending, the near bracket does not quite fit into the groove, and it may even fall out. Therefore, we had to bend it more to ensure a secure fastening of the turntable.

    Only one 4-pin connector is required to connect the novelty, thanks to the appropriate adapter included in the kit. The length of the wires from the fans is 30 cm, which will be quite enough to connect even to the most remote connectors.

    Installation process

    Installing the SilentiumPC Grandis XE1236 V2 cooler is described in great detail in the complete instructions, as well as in videos on the manufacturer’s official website. The process itself cannot be called complicated, but some nuances still took place, so below we will share our experience.

    Let’s traditionally start with a system based on AMD processors. Immediately, we note that the novelty has a twin with the designation «V1» in the title. They differ from each other only in the way of mounting: if the first version uses an X-shaped device for mounting, then the SilentiumPC Grandis XE1236 V2 uses a more familiar universal plate. Therefore, we begin the installation process with this element.

    First, remove the standard mounting on the motherboard, freeing the mounting holes. Next, we install screws into the reinforcement plate, put on anti-vibration pads and mount the resulting structure on the motherboard.

    On the reverse side we put on four plastic racks. On top of them we fix the corresponding metal fasteners with the help of curly nuts and a complete key. Note that the kit contains two types of mounts for the AMD platform, allowing you to install the new product in different ways: so that the heated air is discharged to the back wall or to the top.

    After that, install the processor, apply the thermal interface and mount the cooler. As you can see, the gap between the pressure plate and the mounts installed on the motherboard is too large, so the supplied screws, due to their small length, did not allow us to carry out the installation.

    The solution turned out to be very simple: we evenly loosened the nuts holding the metal brackets to the motherboard on all sides. Thus, it was possible to level the existing gap and fix the novelty in place.

    When using only an internal fan or mounting a second fan on the left side of the cooler, the radiator will only partially cover the first slot for installing RAM. Therefore, modules with a high heatsink can be installed in all slots except the first one. Memory sticks with or without low heatsinks can be used in all slots.

    The second spinner attached to the right covers the slots in such a way that you can only try to install a high module in the farthest one.

    The black painted top plates match the pre-installed turntables. And since the design of our bench components is also characterized by the predominance of black, the complete system has an even more pleasant appearance thanks to the successful combination of dark shades.

    Installing the SilentiumPC Grandis XE1236 V2 cooling system on platforms with Intel processors is almost the same. Here, other reinforcement plate mounting holes are used, which are initially expanded in order to be compatible with all current platforms.

    Appropriate metal mounts are mounted on the front side, which are also universal for a number of Intel platforms.

    After installing the processor and applying the thermal interface, the heatsink itself is fixed to them. In this case, there is no such nuance as with the AMD platform, but the screws with curly heads for fixing the cooler could still be made longer to increase the convenience of their use.

    Compatibility is all right here. If only the internal turntable is connected, high RAM modules can be installed in all slots. But if a second fan is used on the right side of the cooler, the overclocker memory bar can only be installed in the last slot.

    The complete system looks very harmonious. Note that for a more convenient assembly, it is best to additionally arm yourself with a screwdriver at least 15 cm long. located at a sufficient distance from the CPU cooler.

    It’s nice to note that the SilentiumPC Grandis XE1236 V2 cooler did an excellent job. The AMD platform, which is traditionally a more difficult test for the tested coolers, turned out to be quite within the power of the new product. So, at the maximum speed of rotation of the blades, it showed a result at the level of other high-performance solutions. At the same time, the rotational speed itself is relatively low (1450 rpm), which is also reflected in the noise level accordingly. With this indicator reduced to 1100 rpm, the novelty still copes with the cooling of the overclocked six-core processor. So you can count on not only good acceleration performance, but also the ability to reduce the rotation of the blades to create more comfortable acoustic conditions, sacrificing only 2-4 ° C.

    Due to the lower heat dissipation, the Intel platform allowed us to test the capabilities of the novelty in five different modes, differing in the speed of rotation of the blades and the number of fans used. As can be seen, the results are good in all cases. Moreover, on this testbed SilentiumPC Grandis XE1236 V2 even managed to outperform some models that showed an advantage in the previous test. Thus, the results obtained are comparable with 140 mm and other high-performance dual-fan solutions. Even when the blade speed is reduced to 1100 rpm, the temperature of the overclocked test processor increases by only 1-2°C, which gives a good margin for further reduction in speed or trying to achieve higher overclocking results. But at a speed of 800 rpm, the novelty yields another 3°C, and in this case, its efficiency is comparable to using only one internal fan, but with a maximum speed. Note that even one fan operating at 1100 rpm will be enough to remove heat from an overclocked to 4.5 GHz quad-core processor from Intel.

    Recall that the operation of a conventional PC is more variable, so in games and other applications that do not permanently load the processor by 100%, you can count on even lower temperatures.

    With 300W of thermal power removed, the tested cooler performed excellently. Even with one installed fan, he was able to cope with the task at the minimum speed of rotation of the blades. When installing a second fan, the temperature readings obtained are consistent with other high-performance solutions of a similar design that we tested.

    The noise level of the novelty remains quite low over the entire frequency range of the fans. Even at maximum rotation speed, the tested cooler will not disturb your acoustic comfort. And if you want a quieter system, you can always lower the speed to 1100 rpm or even silent 750-800 rpm. In this case, you will have to put up with a slightly higher processor temperature, or sacrifice a hundred or two megahertz during overclocking.

    Conclusions

    The SilentiumPC Grandis XE1236 V2 cooler from a Polish company received a fairly common double-tower layout with two 120-mm fans, which is typical for many productive models. Based on the results of our acquaintance, we confidently attribute the novelty to the category of highly effective solutions.

    At the base of the two towers are six U-shaped copper heat pipes, on which aluminum plates are strung. The latter are placed somewhat denser than in many other solutions, which made it possible to increase the heat transfer area. The base of the cooler is represented by a copper heat sink, to which heat pipes are soldered to improve thermal conductivity. All this together made it possible to obtain a fairly efficient radiator, which had the best effect on the capabilities of the cooling system itself.

    There are several options for active cooling of the novelty. For not too powerful processors, the internal pre-installed turntable is quite enough. In our case, it was able to cope even with an Intel Core i5-2500K overclocked to 4.5 GHz. If you want to increase the efficiency, there is another fan in the kit, as well as a pair of brackets for installing a third turntable, but you will have to buy it separately. When installing an additional fan on the side of the memory slots, please note that in this case you will not be able to use modules with high heatsinks. Without the right propeller, you can use overclocker memory sticks in all (Intel platform) or the last three (AMD platform) slots. In general, the efficiency of the novelty and compatibility with RAM correspond to solutions of a similar design from other manufacturers. As for the noise from the turntables, it won’t bother you even if you use both fans at maximum speed. However, you always have the opportunity to reduce the speed of rotation of their blades to an even lower level.

    Unfortunately, the cooler was not without nuances. The first concerns the process of installing new items on AMD platforms, where the fixing nuts had to be slightly loosened, since the clamping screws were not long enough to reach the mount installed on the board. The second remark concerns the brackets for mounting the fan. We got some of them bent, so they did not fit into the grooves of the radiator, therefore, they did not provide proper fastening of the radiator. This is corrected by their alignment. It is possible that this defect appeared not through the fault of the manufacturer, but our colleagues from other publications, who did not handle the device entrusted to them with care.

    Despite the shortcomings listed, we are confident that with a well-thought-out price tag, the SilentiumPC Grandis XE1236 V2 cooler will become a completely competitive solution on our market. And all thanks to the fact that it allows you to maximize the use of modern processors with unlocked multipliers, while not sacrificing acoustic comfort at all.

    Advantages:

    • high efficiency;
    • low noise;
    • compatibility with all current and some legacy platforms;
    • includes an adapter for connecting two turntables to one 4-pin power connector;
    • fully compatible with nearby heatsinks and connectors;
    • AMD platform mount provides multiple options for mounting the cooler;
    • easy to install on the Intel platform.

    Features:

    • when installing the turntable on the side of the RAM slots, only modules with or without low heatsinks can be used;
    • when installing on an AMD platform, you will need to loosen the nuts that secure the metal fasteners to the racks.
