Description

The Liquid Freezer II ARGB combines the efficient, award-winning PWM pump of the Liquid Freezer II series with new RGB fans optimized for static pressure. This gives you a completely new aesthetic with extremely low noise and equally low temperatures.

Future-Proof Compatibility

In late 2022, AMD released the AM5 socket, the successor to the popular AM4 platform. For this reason, Arctic maintained all mechanical dimensions identical, so that the compatibility of their coolers aligns with AMD's new processors.

Optimized for AMD Ryzen

AMD has been using a new multi-chip layout for high-end AM4 processors for several generations. In these processors, the hotspot is not centered by the IHS (Integrated Heat Spreader).

To continue to enable optimal heat dissipation, Arctic developed a special mounting kit for the Liquid Freezer II that allows the placement of the cold plate directly over the CPU's hotspot.

The upcoming AMD AM5 7000 series processors also feature multi-chip layouts and can therefore benefit from the unique offset mounting of the Liquid Freezer II.

Efficient Silent Pump

The Liquid Freezer II 420 water cooling system by Arctic is silent and high-performing. Its water pump is controlled by PWM, which adjusts its speed accordingly. This not only results in significantly lower noise levels at low and typical loads but also in much lower power consumption for all AiO components.

Premium Class Radiator

The 38mm thick radiator with high fin density allows for the use of a larger amount of water in the circuit and significantly increases the cooling surface area.

Water has a much higher heat capacity than aluminum or copper. This results in a slower temperature increase, up to 5°C lower, during the time-limited turbo operation of modern CPUs.

Silent VRM Fan

Small fans have a reputation for being particularly noisy and not very durable - that's why Arctic started developing a quiet, durable diagonal fan specifically for the Liquid Freezer II.

The fan is PWM controlled and can cool the voltage converters and socket area almost silently by up to 15 °C, especially in overclocking scenarios, with insufficient VRM cooling or in cases with low airflow, thus allowing continuous high load.

High-quality tubes with integrated cable management

The 45-centimeter fiber-reinforced tube allows installation even in large cases and effectively prevents the evaporation of the coolant, so you don't have to worry about refilling it.

Additionally, the advanced cable management hides the PWM cables of your radiator fans within its lining.

Optimized Fan

The illuminated P fans are already mounted on the radiator from the factory. During the development of the new P series fans, particular emphasis was placed on focused airflow and, consequently, high static pressure. The fans guarantee extremely efficient cooling, even with increased air resistance.

Therefore, the P series fans are particularly suitable for use in heatsinks and radiators.

  • The installation was very easy following the instructions for rev.5 in offset. The screenshots are after 3 hours of World of Warcraft retail, raid and open world, at a room temperature of 21-22°C. PBO enabled, curve optimizer -30.
    In complete silence, a slight humming can be heard from the fan motors.

  • I have had it for 3 years, and within those 3 years, 2 of its fans have broken and I am forced to go through the trouble of buying new fans because they wouldn't spin, and IF they remembered to spin, they sounded like a compressor and buzzed throughout the office. I should add that I have connected the water cooling to a particularly good Asus Dark Hero v3 motherboard with a Ryzen 9 5950X, in the appropriate pump and fan headers. I bought it for around 115 euros, you get what you pay for, it's better to go for something more expensive if you want it to last, like Corsair or even better Be quiet, I think those are somewhat top of the list and more durable

    Huge and effective as is logical for a cooler of this size. However, there is often a problem with some motherboards that have, for example, capacitors at the edges, and sometimes the cooler needs to be installed before the motherboard or it may just barely "hit" components of the motherboard and not fit at all. Do a good compatibility check for both the case and the motherboard. It keeps an i9 very satisfactorily cool, without overclocking and without making any noise. We played demanding games and when it ramped up, it was audible, but it didn't bother us...

    The best of all 14mm fans in benchmark cr32 multi core. I didn't go above 81 degrees. 13900ks ..... 338w

    Very powerful cooling keeps the Ryzen 9 5900 x at 60°© during gaming hours in August while it was 40 degrees outside. In idle, it keeps it at 30 degrees without making any noise. It was installed in a Fractal Design Meshify C Tempered Glass Midi Tower case, which essentially doesn't fit, but it works perfectly!

    The liquid cooling is quite good. It doesn't fit in all cases, it's quite bulky, and it really tames a Ryzen 9 5900x in a Darkbase 900 Pro case for 6 hours of 2k gaming with all settings on ultra and v-sync enabled. It never went above 52 degrees.

    First of all, the cooling is great! It barely fit in the Lian Li Evo XL. In terms of temperatures, it is the best AIO I have seen, and there is no throttling even at 100% CPU usage on the 14700KF+(contact frame). The noise is satisfactory in silent mode, but even at full speed, it doesn't hurt your ears. The installation for the backplate screws was a bit strange. The most important thing is that the price at 130 euros, including shipping, is unique for its performance, as this specific liquid cooling is possibly the best on the market!

    Real beast! I have it with the 13900K and the thermalright contact frame, idle temperatures are 19-25 degrees and in a 10-minute stress test with cinebench it doesn't go above 89 degrees and gives 341 watts! The only negatives I can find are the appearance (although that's subjective) and the size. It's really huge and will fit in very few cases, I have it in the corsair 7000d and it's comfortable. It's the best value for money right now, I believe. And from my experience, Arctic has one of the best customer support which is very important, they will assist you immediately no matter what happens.

    I put it in a Corsair 7000D airflow case with an AMD 7900x CPU.
    Even with 24 threads at 100%, it doesn't reach the maximum 95c, it stays at 85c
