ARCTIC Liquid Freezer II 240 - Multi-Compatible All-in-One CPU AIO Water Cooler, Compatible with Intel & AMD, Efficient PWM Controlled Pump, Fan Speed: 200–1800 RPM, LGA1700 Compatible - Black

Best CPU Water Cooler

The Liquid Freezer II series 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.

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

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.

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 the PWM cables of your radiator fans in the sleeving. This makes installation easy and tidy: you only have to connect one connector to the mainboard, and there are no other cables to hide.

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, ARCTIC will send you a replacement (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.

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.
