Arctic Cooling Liquid Freezer II 240 RGB AIO CPU Cooler Packaging

The retail packaging for this product is compact, considering there’s a full AIO system inside. Its cardboard box has a nice matte finish to it. 

In front, you’ll find a black and blue image of the cooler. Here, you’ll also find a label stating that it comes with a 6-year warranty. This will ease the minds of potential customers when considering this AIO CPU cooler. 

On the upper-left corner, you’ll find Arctic and its logo. Then on the lower-left section is the name of the unit. 

Both sides of the box feature QR codes though they bring you to different sections on the Arctic website. The QR code on one side is for technical support and for sharing feedback. The other side has a QR code for “more details”, a specifications table, and a summary for features. 

Also, the cooler for our Arctic Cooling Liquid Freezer II 240 RGB AIO CPU cooler review was well-packed. It came wrapped in plastic and had cardboard around to further protect it from unnecessary bumps and damages during shipping. We think Styrofoam would’ve been more snug and secure, but nevertheless, the thick cardboard still worked anyway. 

Just like with other AIO coolers, the Cooling Liquid Freezer II comes with all the mounting hardware needed. And what’s good is that these are what’s necessary for both the AMD and Intel systems. You’ll find multiple sets of standoffs, screws, mounting clips, and brackets. 

Together with its installation hardware, the company included a syringe filled with their MX-5 thermal compound which is quite convenient. 

Arctic Cooling Liquid Freezer II 240 RGB AIO CPU Cooler Review – Design and Functionality

As the name of the product implies, the Cooling Liquid Freezer II is a 240mm AIO CPU cooler. And with a lot of new AIO’s around, this particular product brings together a CPU pump unit and water block. These are connected with the help of braided cooling lines that lead to a radiator. 

Its black-clad design was applied to the radiator that features Arctic’s branding at the top. You can also find this along the bottom edges of the radiator. 

Shifting to the CPU’s combination unit, you’ll find a slightly-different looking design when you compare it to other similar products. The company chose a stealthy-looking design for their cooler which looks great and sophisticated with its black plastic casing. 

The cooler has two preinstalled and organised 120mm P12 PWM PST RGB fans in the push configuration. If you’re looking to shift to a pull configuration, changing the fans around it is simple. 

The centre hub of the fans has the company’s logo on it, along with RGB lights in sight. Additionally, the fans come with anti-vibration rubber pads on both sides. 

The design of the product is also beneficial when it comes to adaptability for small cases including a mini ITX. This is because the block has an extremely tight width that’s 120mm. 

The 38mm thickness makes it a bit thicker compared to its competitors. And with the fans, it’s able to generate a 63mm block.  

We should consider the thickness when it comes to extremely small cases or low-ends. However, spaces of around 70mm are usually allowed. 

The aluminium block has a collection of longitudinal ducts: half is for the outbound while the other is for the return. As for the return chambers at both ends, these remain protected by the metallic frame. So, they’re able to generate very resistant square corners. 

We’re also checking the lighting and cables in our Arctic Cooling Liquid Freezer II 240 RGB AIO CPU cooler review. 

When it comes to its lighting system, it has a backlight with RGB diodes. And, it’s compatible with the primary plate lighting technologies today like Gigabyte’s RGB Fusion, ASUS’ Aura Sync, and more. 

For the cables, all these for powering the fans/backlight are beneath the braid together with the available hoses. And, the power supply of the complete AIO is a single 4-pin PWM cable for the fan. There’s also one 4-pin RGB cable available. 

Key Features of the Arctic Cooling Liquid Freezer II 240 RGB AIO CPU Cooler

LGA 1700 Compatibility

The Liquid Freezer II comes with the LGA 1700 mounting kit, making it compatible with Intel’s Alder Lake processors. Although its heat spreader and socket are larger than the predecessor, it has a reduced CPU surface that remains centred.

The Ideal Configuration for All

With the cooler’s long hoses and lighting options, it’s a highly versatile CPU cooler that’s compatible with different systems. That means, you can use it effectively in both small and big towers. But of course, you need to watch out for the radiator’s thickness.

Lighting up Your Build with the Arctic Cooling Liquid Freezer II 240 RGB AIO CPU Cooler

The PWM pump of the Liquid Freezer II RGB features optimised RGB fans for static pressure. These provide you with superior, noise-free cooling that maintains low temperatures, as well as new aesthetics.

In-house Developed Pump

Unlike a lot of competitors, the Liquid Cooler II’s water pump is developed in-house. As a result, it performs more efficiently with significantly reduced humming and lower noise levels. Like the other components of the cooler, the pump is PWM-controlled.

Premium Radiator of the Arctic Cooling Liquid Freezer II 240 RGB AIO CPU Cooler

Unlike most AIO cooler manufacturers, Arctic relies on 38mm thick radiators with high fin density. With that, more water can be utilised in the circuit to increase the cooling surface.

Since water has a higher heat capacity than copper or aluminium, this cooler offers a slower temperature increase.

Smooth VRM Fan

Small fans are known for being loud and fragile, but Arctic has developed a quiet and durable diagonal fan. This 40mm VRM fan is just as durable as the company’s other case fans. If it fails, Arctic’s customer service team will send a replacement free of charge, without replacing the whole unit.

Like the Liquid Freezer II’s pump, the fan is PWM-controlled and it can cool your base area and voltage transformers. It’s effective for overclocking, cases with poor airflow, and inadequate VRM cooling. You can also switch it off manually if your system has sufficient VRM cooling.

High-quality Hoses and Built-in Cable Management

The fibre-reinforced EPDM tubing of the Liquid Freezer II allows installation even in large cases. This feature also effectively prevents the evaporation of the coolant so you won’t worry about refilling the water cooling system.

In addition, there’s an integrated cable management system that hides both the RGB and PWM cables of your radiator fans.

Optimised Fan on Static Pressure

We continued working on our Arctic Cooling Liquid Freezer II 240 RGB AIO CPU cooler review. And here, we saw that the illuminated P-fans were fixed to the compact water cooling system right out of the box. What’s good about it is that it works with a couple of advantages. 

Increased static pressure for optimised cooling performance (1.8mm h3O) and extended speed range of 200 to 2,000 RPM. It has lower power consumption at 0.11A, decreased rubber bumpers and vibration that’s reduced by >95%. 

Additionally, it has an enhanced lifetime, high-quality plain bearing, PWM for syncing fan/pump controls, and RGB sharing. The latter is specifically for simultaneous lighting. 


The Arctic Liquid Freezer II is an AIO CPU cooler that’s compatible with AMD’s AM4 sockets. It also works with Intel’s LGA sockets including 1200, 115X, 2011, 2066 sockets. Plus, the company packed this CPU cooler with a mounting kit for the LGA 1700 sockets.

This AIO unit has an unlimited RAM clearance and its operating ambient temperature is between 0 and 40°C. This product also comes with a 6-year limited warranty.

Pump/Cold Plate

There’s a 40mm VRM fan with an RPM of 1,000 to 3,000 that’s PWM-controlled. Plus, its pump that’s PWM-controlled as well can handle a working frequency ranging from 800 to 2,000 RPM. 

The total power it consumes is 0.5 to 2.7W (pump and VRM fan). For its cold plate, it is made of copper with micro-skived fins. There’s an MX-5 0.8g of thermal paste present as well. 

See also


The Cooling Liquid Freezer II has two ARCTIC P12 PWM RGB 120mm fans. These have a speed of 200 to 1,800 RPM and a fluid dynamic bearing. 

Their noise levels are at 22.5 dBA, voltage & current are 0.08A & 12V DC. The fans’ airflow is 48.8 CFM while static pressure is 1.85mm h3O. And, ARCTIC made use of a 4-pin connector for the fans.  


The LEDs used are 12 RGB LED lights per fan which makes use of a 4-pin 12V-G-R-B connector. For the current/voltage, it’s at 0.2 A/12V. 

Size & Weight

The radiator is 277 x 120 x 38mm and the pump without tubes is 98 x 78 x 53mm. Its outer tube diameter is 12.4mm while the inner tube is 6.0mm. For its tube length, it measures 450mm. 

It weighs a total of 1,191g when you include the radiator, fan, pump, and tubes. 

Let’s continue our Arctic Cooling Liquid Freezer II 240 RGB AIO CPU cooler review by checking how it performs. 

Hands-on with the Arctic Cooling Liquid Freezer II 240 RGB AIO CPU Cooler 

Before we get to the actual performance of the Cooling Liquid Freezer II, let’s discuss its installation process. 

When we installed the product, the first thing we had to prepare was the backplate. We slid the screws into the correct slot on the backplate before utilising the washers to secure these. 

Then, we were able to position the backplate on the board then used the standoffs and washers to secure them. After that, we secured the mounting arms to their standoffs. 

Threaded holes were offered for the thumb nuts along the cooler mounting bridge. With these, the heatsink was properly secured. The last and easy part was plugging it into the fan header, then that’s it. 

For our Arctic Cooling Liquid Freezer II 240 RGB AIO CPU cooler review, we also tested the product. This is to help you decide if this cooler is something you need for your PC.

During our initial base frequency test, the Liquid Freezer II already delivered great cooling performance. 

The CPU’s temperatures were 23°C at idle mode and 59°C under load. 

The Liquid Freezer II was able to maintain low temperatures even under heavy loads even when we overclocked our CPU. 

Aside from keeping our processor cool and under control, it was one of the most quiet coolers we’ve used. Its noise level was only at 32dBA during idle mode and 39 dBA under loads. 

Arctic Cooling Liquid Freezer II 240 RGB AIO CPU Cooler Review Summary

We loved the product that we tested for our Arctic Cooling Liquid Freezer II 240 RGB AIO CPU cooler review. It’s an excellent cooler that has an elaborate design and offers superior performance too. It can cool high-end processors without noise and is excellent for overclocking.

We also appreciate the small changes like the two included RGB fans and the new MX-5 thermal paste. The redesigned syringe-shaped applicator of the latter allowed for easier application when we were installing the cooler.

Another thing we liked about this cooler is its built-in cable management. This allowed us to easily install the cooler faster.

Overall, it’s a well-designed cooling system that offers great performance. Since it’s compatible with Alder Lake processors, it’s one of the options we highly recommend if you’re upgrading your PC.

Introduction, Packaging & BundleTesting MethodologyTesting ResultsFinal Words & Conclusion

Arctic Cooling is a company originating from Switzerland and has risen to prominence for their advanced cooling solutions. The company was founded back in 2001 and offered some of the best thermal compounds available at the time. Today, cooling products remain the core focus of the company, but they also offer a few other products as well, such as advanced monitor mounts and audio peripherals.

Over the past several months, Arctic Cooling has been picking up from a dry spell in top-tier CPU coolers, having gone a few years since their previous release. Last year, the company introduced the first parts in their their Liquid Freezer II all-in-one liquid cooling series, expanding the range as the months went by. A few weeks ago the company announced the release of the massive Liquid Freezer II 420, triple-fan AIO cooler that holds not three 120mm fans – as is usually the case with triple-fan coolers – but three even larger 140 mm fans. Arctic Cooling set out to cover the market from bottom to top with their Liquid Freezer II coolers, and the introduction of a 420mm design has certainly cemented that status.

In this review, we are taking a look at a couple of Arctic Cooling’s Liquid Freezer II coolers. We’re of course diving into the behemoth 420 AIO cooler, but also the much more sensible 240mm version of the cooler. How well does such a large cooler perform with regards to thermals and noise? And just how much better does that make the super-sized cooler over the more normal, widely compatible version of the same cooler? Let’s find out.


Packaging & Bundle

Arctic Cooling supplies the Liquid Freezer II series in relatively simple but sturdy recyclable cardboard boxes. The artwork on the box is based on a schematic of the cooler itself, with plenty of information regarding the cooler on the backside of the box. Inside the box, we found the coolers and their parts well protected by cardboard inserts and nylon bags.

The bundle supplied with the Liquid Freezer II coolers is the same regardless of the cooler’s size. Unfortunately, the MX-4 thermal compound that the company advertises to be included is a single dose, not a whole tube. The rest of the bundle consists of the necessary mounting hardware, all in black color. There is no paper manual but there is a card with a QR code, which in turn leads to an downloadable manual.

The Arctic Cooling Freezer II 240 / 420 Coolers

As expected, the main difference between the 240 and 420 versions of the Freezer II is the size of their radiators and fans. Other than that, the two all-in-one (AIO) liquid coolers are identical, using the same main block and tubing. The core design of the coolers is the typical AIO configuration of a single radiator, two hoses, and a block that combines the CPU contact plate and a miniature liquid pump. One major divergence compared to competitive products is that the fans are already installed onto the radiators and everything is pre-wired, with the whole assembly powered by a single 4-pin connector coming out of the block. And while pre-assembly isn’t strictly necessary for an AIO cooler, anyone who has assembled a cooler can probably appreciate the time saved by not having to line up screws, power cable orientations, etc. Furthermore, recognizing that some users may want to reconfigure and reassemble the cooler anyhow, the company’s designers added regular fan connectors onto the radiator, meaning that one can seamlessly replace the fans if needed.

Arctic Cooling is using high-density rubber for minimal long-term evaporation that should last for the lifetime of the cooler, with no filling/service ports to be found. The hoses are protected by a nylon sleeve with a circular dual silver thread design. The nylon sleeve also hides the cable that powers the fans. Chromed metal press fittings are used to secure the tubing on both ends.

The radiators of the Arctic Cooling Freezer II AIO coolers are dual-pass cross-flow designs with tiny fins soldered on thin oblong tubes, yet they are not based on the same exact design that most AIO coolers use. Regardless of variant, all of Arctic Cooling’s Freezer II radiators are rectangular constructs that are significantly thicker than standard designs, measuring 38 mm thick without the fans and nearly 65 mm with the stock fans attached. The 420 version of the Freezer II also sports the largest radiator we have seen used by an AIO cooler to this date and comes with three 140 mm fans installed. It is not the longest, as there were a few 4×120mm (480) radiators circulating the market over the past few years but, even compared to these, it has significantly more heat exchange area. Consequently, case compatibility may be a challenge for this behemoth.



The main block assembly of the Freezer II is short and relatively simple, with one major difference discerning it from most competitive products – there is a small 40 mm fan attached to it. This fan has practically nothing to do with the cooling of the CPU itself but is meant to provide some airflow to the motherboard’s power circuitry that would normally be cooled by the air cooler’s airflow. Other than that, the assembly includes the copper contact plate and the mini pump.

The square copper contact plate is not machined down to a complete mirror finish but is very smooth. It is large enough for most commercial processors but will not cover a ThreadRipper processor, for which the Freezer II coolers have no stock support for out of the box.

Review Arctic Liquid Freezer II — 360 A-RGB. Liquid cooling with heat dissipation from VRM

As part of the «Laboratory», we tested the Arctic Liquid Freezer II 360 with an interesting implementation of the water block, in which an additional fan was installed to reduce the temperature in the area of ​​\u200b\u200bthe power piping of the motherboard. Not long ago, they updated it, keeping the key engineering decisions and adding controllable A-RGB backlighting. Released in several sizes: 240, 280 and 360 mm.

They come with a 6 year warranty. We have conducted detailed testing of the Arctic Liquid Freezer II — 360 RGB and today we will share our operating experience with you.


Packed in a cardboard box with detailed information on the characteristics and features of the work. See the reverse side for detailed technical information.

Inside the box, the system is shipped assembled. The kit includes a reinforcing plate, support pads, a set of screws and brackets, support posts, self-tapping screws, anti-vibration pads, a tube of MX-5 thermal paste.

On the side of the box there is a QR code with a link to a page with a video describing the installation process.


As before, the waterblock block is combined with the pump. It is accompanied by an additional fan.

When operating, it creates an airflow that directs air to the heatsinks and power elements around the socket.

Its base is copper. The surface is flat. Area 44 by 40 mm.

The casing of the water block is plastic. The overall profile is low. Two cables come out: an ARGB sync cable and a 4pin PWM cable.

In the Arctic Liquid Freezer II — 360 A-RGB, the issue of cable management was considered from the very beginning. The fan cables are assembled into a common circuit and neatly stacked. Only two cables are connected to the motherboard and another separate one for the fan on the water block.

The hoses are 45 cm long. The joints are additionally pressure tested and reinforced. They come wrapped in nylon.

The radiator is made of aluminium, painted black. Thickness 38 mm. Three P12 PWM PST fans are pre-installed on it.

Arctic Liquid Freezer II 280 Overview. Vigorous bomb for the liquid coolant market — Page 3 of 5

Arctic Liquid Freezer II 280 coolant is made according to the classical scheme: a water block combined with a pump, a pair of nylon-braided hoses, a radiator with small reservoirs on the sides, and of course a pair of fans. However, each of these components has a special feature that distinguishes the brainchild of Arctic from competitors. Let’s take a closer look in the same order.

The water block is very different from what we are used to seeing in various coolants based on the design of the Danish company Asetek. Arctic took care of additional airflow for the motherboard power supply unit heatsinks.

A 40 mm centrifugal type propeller is responsible for blowing air, which captures air from above and throws it out to the sides. The rotation speed is adjustable in the range of 1000-3000 rpm. At a minimum it is inaudible, but at maximum speed it already stands out.

Decreased temperature of the VRM-node and near-socket space by rather big 15 degrees. However, 60 degrees for the power circuits of the board is very ok.

If the motherboard has a powerful VRM node and / or an economical processor, or you just don’t want an extra buzzer (and the speed is regulated along with the pump and the main 140mm propellers), the small fan can be turned off completely.

The pump speed is also controlled by PWM, which distinguishes the Liquid Freezer II from other inexpensive dropsies. Range — 800-2000 rpm. What kind of bearing is based on is not specified, but judging by the 6-year warranty, the bearing is ceramic. The pump is very quiet throughout the entire rotation range, and is completely indistinguishable against the background of a 40 mm fan. Productivity in liters per minute is not specified.

Copper base without nickel plating. Not very good, because over time the copper will oxidize and a degree or two will be lost, and it is not so easy to clean the copper plate from the old thermal paste. It’s great that the plate is fastened with screws for a regular Ph3 slot. In a couple of years it will be possible to remove it and clean the microchannels, and also, albeit using the collective farm method, but add liquid.

The plate is very well polished, even with claims to specularity. For pure copper, this is the top level. Good flatness can be noted immediately by shagreening …

… which is confirmed to the light with a calibrated square.

Hoses of standard length by the standards of decent LSS — 450 mm. In a loose nylon sheath, which looks somewhat «shrunk», uneven. The outer section of the hoses is 12.4 mm, the inner section is 6 mm as standard. Under the braid of one of the tubes is a fan power cable.

Although in other reviews the authors indicated fittings on the thread, I could not unscrew them, even holding them in a vise. The fittings are made of plastic and look cheap, frankly. The most unpresentable element of the Arctic Liquid Freezer II.

But the radiator is my respect. Typically, the coolant radiator has a thickness of 27 mm, for Liquid Freezer II as much as 38 mm. Together with fans and screws, the thickness increases to 68 mm (without screws 65 mm). On both sides of the radiator there are additional tanks of 18 mm each (usually only one). General dimensions 317×138 mm. It is worth double-checking that the case can accommodate such massive cooling, and especially in terms of conflicts with the video card.

14 channels pass through the radiator, between which there is corrugated tape. Density 14 FPI (plates per inch). But corrugated tape is not so simple. If you look closely, this is not a solid smooth aluminum tape, it is notched. It is difficult to judge how much this approach is better than a conventional tape. On the one hand, the scattering area is much larger. On the other hand, there are more turbulences, for normal purge, high speeds are required, but the radiator is not thin. Due to the rather large mass and large amount of refrigerant, the heat capacity of the radiator is simply enormous.

The heat exchanger is blown by a pair of 140mm Arctic P14 PWM propellers. They are slightly thicker than the standard 140 mm «turntables» — 27 versus 25 mm, and also noticeably heavier.
