"Everything considered, the Alpine 11 Pro is a champ ..."
Excellent Cooling Perfomance
A 92 mm PWM fan on an aluminum extrusion heatsink in combination with pre-applied MX-2 high performance thermal compound provide good cooling performance and improve heat transfer from the CPU. In a test conducted by Dragon Steel Mods, the Alpine 11 Pro successfully reduced the CPU temperature of an Intel Q6600 by 6 degrees.

Ultra Quiet

Its low noise impeller, patented fan holder and anti-vibration parts ensure the fan to work quietly even under full load.

The test done by TweakTown has shown that the Alpine 11 Pro is 14 dBA and 9 dBA lower than the AMD and Intel boxed cooler respectively at full load.

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.

Noise Level at Intel Core i7-4770
Alpine 11 Pro (at 2,000 RPM)
0.4 Sone
Stock cooler (at 3,000 RPM)
1.75 Sone

The Alpine 11 Pro features wide compatibility with Intel sockets. Its simple mounting system is designed to fit most of today's CPUs.

The Alpine 11 Pro is compatible with Intel Sockets 1150, 1151, 1155, 1156, 775.

Vibration Absorption
Quick Installation
The patented vibration absorption fan holder is the key to keep the Alpine 11 Pro inaudible. It absorbs vibration caused by the spinning of the fan and thus it's barely heard even when it's running at full speed.

Installation is a breeze with the push pins. The pre-applied MX-2 high performance thermal compound makes the installation a quick and clean process.

How to configure the PWM settings?read

You can only configure the PWM settings via the BIOS. Otherwise, please check the manual for your mainboard.

* The interface varies for different models and the fan speed -settings may be hidden somewhere.

Here's an example with ASRock H170 Pro4/D3.

1. Enable CPU Fan Setting

2. Modify "CPU Fan Setting" by choosing Customize, Silent Mode, Standard Mode, Performance Mode or Full Speed.

Instead, you may be asked to configure a target temperature for your CPU. In this case, we recommend entering a value of 65°C. Some BIOS may require a minimum percentage for the PWM-control. The value entered should be at least 25%.

The fan on Alpine 11 Pro has stopped working

You can purchase a spare fan which is compatible to Alpine 11 Pro and Alpine 11 Pro in our webshop.

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.
