ARCTIC Alpine 20 PLUS CO Intel Socket LGA 2011

130 Watts, 600 - 2200 RPM, 92 mm Excellent Cooling Performance
The 92 mm PWM fan, aluminum heatsink in combination with pre-applied MX-4 high performance thermal compound provide excellent cooling performance and improved heat transfer from the CPU. Test results from Mod Your Case have shown that this cooler is much more efficient than the boxed cooler in lowering the CPU temperature under load.

Ultra quiet
According to a test by VR-Zone, the noise level of this cooler is cut by nearly half comparing the results of the AMD X4 995 boxed cooler. 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.
