ARCTIC Liquid Freezer II 420 Series – Multi Compatible All-In-One CPU Water Cooler - ACFRE00092AARCTIC are proud of there completely new all-in-one CPU water cooler series. For the Liquid Freezer II Series, they have used there 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.Newly 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.Improved Power EfficiencyUnlike most pumps from our competitors, which run at full load even when idle, our pump clocks down if no cooling is needed. This means it consumes less power and produces less noise, even with its additional fan for VRM cooling.Optimal RAM CompatibilityThanks to its compact pump with dimensions of only 78x98x53mm, there are almost no restrictions when using RAM modules. Even RAM modules with larger heatsinks can be mounted without issues and will not be blocked by the CPUcooler.Integrated Cable ManagementThe PWM-cable of the fan is integrated into the sleeveless tubing. Thus fewer cables are exposed for a clean and sleek look within your case.
