ARCTIC Liquid Freezer II 240 A-RGB - Multi Compatible All-in-One CPU AIO Water Cooler


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 also come with multi-die layouts and can therefore benefit from the Liquid Freezer II's unique offset mounting.


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.


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-color lighting effects. With the help of advanced A-RGB Gen.2 technology and customizable LEDs, you can design your system with your very own look.


The all-in-one cooling handles the entire cooling requirements - even of the most powerful processors from Intel® and AMD®. It performs effortlessly with over 200 W of heat to be dissipated, which is why your CPU can be kept cool even in extreme overclocking. When it comes to competitive products from leading cooler manufacturers, the Liquid Freezer II leaves them behind in terms of both performance and noise level.


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.


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 up to 5 °C lower temperature increase in the time-limited turbo mode of modern CPUs.


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.


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.


The illuminated P-fans are already mounted on the radiator from the factory. During the development of the new P-series 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.


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.
