For the Liquid Freezer II, Arctic has used 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 provides an ideal ratio of high CPU cooling capacity and low noise. The AiO water cooler has integrated cable management in the fully sheathed hoses for a clean look in the housing. And the powerful P-fans ensure rapid heat dissipation thanks to their high static pressure and outstanding performance. Self-developed, PWM-controlled water pump The Liquid Freezer II features a completely new, proprietary PWM-controlled pump with copper base plate, improved efficiency, low power consumption and quiet operation. Unlike most other competitor pumps, which also run at full load in idle mode, ARCTIC’s pump reduces the speed at low load and thus consumes less power and runs smoother, despite the additional fan for VRM cooling. Motherboard VRM Fan A 40 mm fan located on the pump cools the voltage converters of the motherboard. Especially with overclocking, this prevents overheating and thus allows for continuous high load.
