" Nothing short of an excellent choice ..."
"Better in every way than the boxed cooler ..."
+ Long lasting fan
+ Easy installation
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.

Alpine 64 PLUS
Stress test with Prime95
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. Click here to see how the PWM control settings can be changed according to your performance and noise preference.

Tested with SL-5868P digital sound level meter
The Alpine 20 PLUS CO is ideal for entry level servers running 24/7, offering an extended service life of up to 5 times of standard models. Its high quality dual ball bearing from Japan reduces rotational friction and is less sensitive to dust and high temperature, making it more durable and wear resistant than the common fluid dynamic bearing.
The pre-installed spring-loaded screws allow a hassle-free setup and at the same time, protect your mainboard during the installation process with optimized contact pressure. On the other hand, it saves you one more step with th pre-applied MX-4 thermal compound.

The PC is reporting a low fan speed during booting.
Your PC may send you a CPU Fan Speed warning when starting the PC if the fan speed is lower than the default minimum value. If you do not wish to receive this warning in the future, you may enter the BIOS to reset the minimum value or disable the function completely.
As shown in the example below, you can adjust the settings under Power -> CPU Fan Speed warning. By setting the value to 800 RPM, you should avoid any warnings of this kind in the future.
