The Alpine 11 GT Makes Your Office or Home PC Quiet
Are you suffering from increasing noise of your dusty and ageing stock cooler?
Or are you a system builder who needs a price competitive yet quiet cooler
for mainstream PCs?
The Alpine 11 GT is your choice - quiet, efficient and quickly installed!
Excellent Cooling Performance
The ultra-quiet 80mm PWM fan and an optimized heatsink give the Alpine 11 GT the best price / performance ratio.

Virtually Silent
The combination of a low noise impeller and the patented fan holder makes the Alpine 11 GT virtually silent even at full fan speed.
Thanks to the PWM control, the speed of both fans adjusts according to the temperature of the GPU 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.

Compact Design
Easy Installation
This compact cooler with a quiet 80 mm PWM fan can deal with a TDP of 70 Watts and thus cool most CPUs. Due to its capability to draw air from the side and its low profile, the Alpine 11 GT is a perfect choice for small form factor PCs.
The approved mounting system via push pins offers excellent stability and is applicable within seconds. The pre-applied ARCTIC 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 GT has stopped working

You can purchase a spare fan which is compatible to Alpine 11 GT and Alpine 11 GT 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.
