Arctic Liquid Freezer II 120mm Multi-Compatible All-In-One CPU Water Cooler At ARCTIC, we are proud of our completely new all-in-one CPU water cooler series. For the Liquid Freezer II Series, we have used our experience in CPU water cooling to develop a completely new compact water cooling pump. The new pump of the Liquid Freezer II Series ensures an ideal ratio of high CPU cooling performance to low noise levels.The CPU AiO water cooler has integrated cable management within fully sleeved tubes for a clean look in your PC’s case. Our powerful P-fans provide a fast heat transfer thanks to their high static pressure and outstanding performance.We recommend the Liquid Freezer II Series, an all-in-one CPU water cooler for those looking for superior performance and low noise level at a fair price.P-fan for Increased PerformanceThe Liquid Freezer II benefits of all advantages of our new P-fan:- High static pressure for increased cooling performance- Broad RPM range- Lower power consumption- Less vibrations- Extended life span- High quality bearing- PWM for synchronous fan/pump controlNewly Developed In-House PWM-Controlled PumpThe Liquid Freezer II Series features an all-new, in-house developed PWM-controlled pump with a copper base, improved efficiency, low power usage and quiet operation.Unlike most pumps from our competitors, which run at full load even when idle, our pump clocks down consuming less power and producing less noise if no cooling is needed, even with its additional fan for VRM cooling.Motherboard VRM Cooling FanAn additional 40 mm fan next to the pump helps to cool the motherboard‘s VRM chips. This prevents overheating, especially when overclocking, and allows for continous heavy loads.Maintenance-free Water LoopThe water loop is sealed, therefore no water or additives have to be refilled.
