For the Liquid Freezer II, Arctic has utilized its experience in CPU water cooling to develop a completely new pump for compact water cooling. Powerful and PWM-controlled, the pump of the Liquid Freezer II ensures an ideal balance between high CPU cooling performance and low noise levels. The AiO water cooler features integrated cable management within the fully sleeved tubes for a clean look inside the case. The high-performance P-fans quickly dissipate heat thanks to their high static pressure and outstanding performance.

The Liquid Freezer II is equipped with a completely new, in-house developed PWM-controlled pump with a copper base plate, improved efficiency, low power consumption, and quiet operation. Unlike most other competitor pumps that run at full load even in idle mode, Arctic's pump reduces its speed under low load, consuming less power and running more quietly, even with an additional fan for VRM cooling.

A 40 mm fan located on the pump cools the voltage regulators of the motherboard. This prevents overheating, especially during overclocking, allowing for consistently high loads.
