Arctic Liquid Freezer II 240 RGB 240mm Liquid CPU Cooler, PWM Fans & PWM Controlled Pump – ACFRE00098ABuilt with Experience Using a wealth of experience gained from previous work on CPU water cooling, Arctic have returned with the Liquid Freezer II 240 RGB a multi-compatible high quality AIO cooler, featuring a custom designed completely new compact water cooling PWM pump and integrated cable management complete with sleeve tubing for a great clean aesthetic. The Liquid Freezer II 240, features 2x powerful 120mm Arctic P12 RGB fans to give you outstanding heat transfer driven by high static pressure, outstanding performance and breathtaking aesthetics, making this all in one liquid water cooler perfect for hobbyists or enthusiasts that are looking for superior performance at lower noise levels. Developed In-HouseThe Liquid Freezer II Series AIO coolers feature a newly developed PWM-controlled pump, boasting a copper base, improved efficiency, lower power usage and quiet operation. Unlike conventional pumps which continuously run at full load even under low demand, the Artic Freezer II series pump clocks down consuming less power and producing less noise if no cooling is needed, even with its additional fan for VRM cooling.Highly Popular P12 PWM RGB fansThe Liquid Freezer II series coolers feature the popular Arctic P12 PWM RGB fans, bringing with them the following advantages;? High Static Pressure? Superb Lighting Aesthetics ? Broad RPM Range (200 – 1800RPM)? Fluid Dynamic Bearings? Lower Power Consumption? PWM for synchronous fan/pump control? Extended Life Span? Less VibrationsHigh Fin Density DesignUnlike conventional AIO radiators, Arctic have opted for a 38mm thick radiator with a high fin density allowing a higher volume of water to be used in the circuit and the cooling surface can be significantly increased.
