Excellent Cooling Performance The unique heatsink design consisting of 102 fins and 4 double-sided heatpipes offers excellent cooling performance and improve heat transfer from the CPU. Tested by Hinnavaatlus, the Freezer Xtreme outperformed the stock cooler in reducing the CPU temperature by 18 degrees. Low Noise Complimented by Hardware Secrets for being the quietest cooler ever tested, the Freezer Xtreme features a central-mounted 120 mm fan with low noise impeller and patented fan holder to achieve quiet operation. Thanks to the PWM control, the fan speed adjusts according to the CPU temperature and thus the noise level remains at an absolute minimum which qualifies it as a silent cooler.
