Liquid Freezer II 420 A-RGB
Multi Compatible All-in-One CPU Water Cooler with A-RGB
At the end of 2022, AMD has released the AM5 socket, the successor to its popular AM4 platform. Because all mechanical dimensions remain identical, we are able to guarantee the compatibility of ARCTIC coolers with AMD's new processors.
Additionally, all coolers shipped by ARCTIC are already compatible with Intel's Alder Lake and Raptor Lake LGA1700 processors.
Coolers purchased from resellers, however, may still have been shipped without the corresponding accessories. In this case, please contact our customer support.
Optimized for AMD Ryzen
AMD has been using a new multi-die layout for its high-end AM4 processors for a few generations now. In these processors, the hotspot is not centered by the IHS (Integrated Heat Spreader). To still allow for optimal heat dissipation, we have developed a special mounting kit for the Liquid Freezer II that allows the cold plate to be placed directly over the hotspot of the CPU. AMD's upcoming 7000 series AM5 processors are also come with multi-die layouts and can therefore benefit from the Liquid Freezer II's unique offset mounting.
Best CPU Water Cooler
The Liquid Freezer II series has been tested numerous times by independent reviewers and praised for its performance, price and quietness. It consistently exceeds all expectations and sets new standards in compact water cooling. As a further mark of recognition, the Liquid Freezer II series was awarded the “European Hardware Award 2022” for the best CPU water cooler.
Create Your Own Look
The Liquid Freezer II A-RGB combines the Liquid Freezer II series' efficient, proprietary PWM water pump with ARCTIC's new A-RGB fans optimized for static pressure. This allows for perfectly matched, multi-colour lighting effects. With the help of the advanced A-RGB Gen.2 technology and customizable LEDs, you can design your system with your very own look.
Efficient, Proprietary Pump
While many competitors use a generic water pump, we‘ve gone to great lengths to develop our own. The results? Quieter operation and higher efficiency. And, like the Liquid Freezer II’s fans, the water pump is PWM-controlled and adjusts its speed accordingly. This not only leads to significantly lower noise levels at low and typical loads, but also a much lower power consumption for all components of the AiO.
Premium Class Radiator
Unlike most all-in-one liquid cooling manufacturers, we rely on 38mm thick radiators with a high fin density. This allows a larger amount of water to be used in the circuit and significantly increases the cooling surface area.
Water has a much higher heat capacity than aluminum or copper. This leads to a slower and an up to 5 °C lower temperature increase in the time-limited turbo mode of modern CPUs.
Quiet VRM Fan
Small fans have the reputation of being particularly loud and not very durable; that’s why we set out to develop a quiet, sturdy diagonal fan especially for the Liquid Freezer II. We’re 100% convinced that this 40 mm fan is just as durable as our other case fans. If the fan doesn’t live up to our claims, our customer service team will send you a replacement free of charge (without you having to replace the entire unit).
The fan is PWM-controlled and can cool your voltage converters and the socket area almost inaudibly by up to 15 °C especially in overclocking scenarios, with insufficient VRM cooling or in cases with low airflow and thus allows continuous high load. Provided there is sufficient VRM cooling, it can be turned off at will.
High Quality Tubing with Integrated Cable Management
The Liquid Freezer II's fiber-reinforced 45 cm tubing allows for installation even in large cases and effectively prevents coolant evaporation, so you don't have to worry about refilling your compact water cooling system.
Plus, our sophisticated cable management hides both the RGB and PWM cables of your radiator fans in the sleeving.
This makes installation easy and tidy: you only have to connect two connectors to the mainboard, and there are no other cables to hide.
Fans Optimized for Static Pressure
The illuminated P-fans are already mounted on the radiator from the factory. During the development of the new P-serie fans, special emphasis was placed on a focused airflow and thus a high static pressure. The fans guarantee extremely efficient cooling, even with increased air resistance. Therefore, the P-series fans are particularly suitable for use on heatsinks and radiators.

The Right Configuration for Everyone
With its long tubing, availability in five sizes, and various lighting options, the Liquid Freezer II series is extremely versatile. It has high compatibility and can be used in Small Form Factor PCs (note radiator thickness!) as well as in Full Towers.
The Liquid Freezer II is the successor to the well-respected Liquid Freezer water cooler from ARCTIC.
