Whisper-quietWhen the fan is spinning at its full speed at 2,000 RPM, the 92mm PWM fan and low noise impeller make the entire operation to be nearly inaudible. The patented fan holder design reduces the unwanted noise by absorbing the vibration from the spinning impeller as well. Reliable performanceThe maximum cooling capacity of Alpine 11 Rev. 2 is 95 watts. Its optimized heatsink design dissipates heat efficiently. The Alpine 11 Rev.2 outperforms the stock cooler in regards to its cooling performance and noise elimination. Easy installationThe unique mounting system via push pins offers excellent stability and is applicable within a few seconds. The pre-applied ARCTIC MX-2 thermal compound makes the installation a quick and clean process.
