Arctic Liquid Freezer II 240 - Review

More and more users are betting on overclocking their processors. This practice can result in an improvement in system performance, especially in games or tasks that require computing. For them we have the Arctic Liquid Freezer II 240 liquid cooling, a more compact solution than the Freezer II 360 that we have recently reviewed. This refrigeration, like its older sister, has a fan next to the pump that allows the VRM phases to be cooled.

Thanks to Arctic for giving us this liquid cooling

Unboxing Arctic Liquid Freezer II 240

RL AiO Arctic liquid freezer II 240 front box

The case of this liquid cooling is one of the most sober that we have come across. Arctic is characterized by being a sober brand that seeks to offer quality products, without unnecessary elements. We see on the front a rendered image of the RL, as well as that it supports AMD Ryzen processors and that it includes MX-4 thermal paste.

If we turn it around, in the back we find the main characteristics of this Arctic Liquid Freezer II 240. The 40mm fan for cooling the VRMs, the tubes, the radiator and also the copper surface stand out from the brand. contact the IHS.

An interesting thing about these Liquid Freezer II liquid coolers is that the fans are mounted. The reason is none other than the wiring, which is inside the protective and beautifying sleeve of the tubes. There will always be those who do not like this, because they want RGB fans.

RL AiO Arctic liquid freezer II 240 fans

One of the peculiarities, as we said, is that the radiator already has fans installed. We are talking about 25mm high fans, which is a standard thickness for fans. They are high static pressure fans, offering 2.2mm / H2O.

RL AiO Arctic liquid freezer II 240 radiator

The most particular thing about this liquid cooling is the radiator, not suitable for all chassis. Only the radiator has dimensions of 38mm, so it is not compatible with most cases. At the end the set of fans and radiator is 63mm. The good thing is that being 240mm we can put it on the front, since the limitation is usually for the cooling of 3 fans.

RL AiO Arctic liquid freezer II 240 pump

This Arctic Liquid Freezer II 240 features a pump that we'll talk about next. Note that the tubes have been lined to offer a more pleasant aesthetic and protect the tubes. In addition, this cover hides the head of the fans, which goes down directly to the pump. The pump and radiator fittings are chrome-plated to add a touch of class to the system.

Features Arctic Liquid Freezer II 240

What's interesting about this Arctic Liquid Freezer II 240 liquid cooling is in the pump. Like most AiO coolers, it sits above the processor. The first aspect is that the pump and fans work in unison to offer the highest possible efficiency. From the RL there is only a 4-pin cable for everything and it is an electronic circuit that regulates the power of the pump and the fans, which are synchronized.

RL AiO Arctic liquid freezer II 240 copper base

We have a small 40mm fan designed to cool the VRM phases. The big problem with tower heatsinks is that they do not help to cool this element of the motherboard. Arctic wanted to add value to this RL AiO and integrate a fan that helps reduce the temperatures of the VRMs.

Indicate that the base is polished copper to offer the least amount of imperfections possible. It is intended that the heat transfer from the IHS to the liquid is efficient. In addition, the circuit passes directly over the copper surface, maximizing system performance.

To test this liquid cooling, the AMD Ryzen 5 2600X processor was used with overclocking at a stable frequency on all cores of 4.1GHz.



This liquid refrigeration Arctic Liquid Freezer II 240, like the 360mm model, is designed for performance. The aesthetics are quite careful, it is undeniable, but elements that do not contribute anything have been saved, such as RGB. It is very interesting that we only have one cable to operate the entire system, reducing the number of cables to manage. We think it's very smart to add a trim cover to the RL AiO and run the fan cable inside.

Adding a fan to help cool the VRM phases compensates despite the added loudness. The truth is that it is quite discreet, you can hardly hear it and it manages to adjust the temperatures downwards. But since everything has negative points, one being that cleaning the fans can be a bit complicated. The most negative aspect is that it lacks a filling and purging plug, so it has an expiration date.

  • Supports the latest Intel and AMD processors seamlessly
  • Efficient design without unnecessary elements
  • Fans and pump are powered by a single cable and run synchronously
  • Specific fan for VRM phases
  • A MX-4 thermal paste kit has been included
  • Fully compatible with all types of RAM
  • Chromed fittings and mesh tubes, with the fan cable passing through the mesh
  • The radiator and fans add up to more than 60mm thick, so before purchasing it, see if your chassis supports it
  • It does not have a purge plug, so we cannot refill it
