Arctic Liquid Freezer II 420 A-RGB Black All In One Open Box Liquid CPU Cooler

Light Up Your Build

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

Efficient, In-House Developed Pump

Unlike many of our competitors, we went to great lengths to develop the water pump. The result is greatly reduced humming and higher efficiency. Like the other components, the pump is also PWM controlled. This leads to a significantly lower noise level at low and typical loads, but also to much lower power consumption, with a maximum of of 0.8 W at no load, 2.3 W under normal load and a maximum of 6.78 W under full load for the entire AiO, without illumination.

Premium Class Radiator

Unlike most other all-in-one liquid cooling manufacturers, we rely on 38mm thick radiators with a high fin density. This means that a larger amount of water can be used in the circuit, and the cooling surface can be significantly increased.

Water has a much higher heat capacity than aluminium or copper. This leads to a slower and up to 5 °C lower temperature increase in the temporary turbo mode of modern CPUs.

Smooth VRM Fan

Small fans have a reputation for being particularly loud and not very durable. However, we have developed a quiet and durable diagonal fan especially for the Liquid Freezer II and are 100 % convinced that this 40 mm fan is just as durable as our other case fans. In the unlikely event that it should fail, our customer service team will send you a replacement free of charge and easily, without a need to replace the entire unit.

The fan is PWM-controlled and can cool your voltage transformers and the base area almost inaudibly by up to 15 °C. This is especially effective in overclocking scenarios, inadequate VRM cooling or in housings with poor airflow, thus permitting continuously high loads. If sufficient VRM cooling is available, it can be switched off at will.

High Quality Hoses with Integrated Cable Management

The fibre-reinforced, long EPDM tubing of the Liquid Freezer II enables installation even in large cases and effectively prevents the cooling liquid from evaporating, so that you do not have to worry about refilling the compact water cooling system.

It also hides the cables of your radiator fans thanks to sophisticated cable management. So you only have to connect a plug to the mainboard, saving valuable time during installation. In the end, you won't need to hide any more cables and your view is reduced to just the essentials.
