Ultra Quiet
The combination of a low noise impeller and the patented fan holder makes the Alpine 11 virtually silent even at full fan speed.

Thanks to the PWM control, the speed of both fans adjusts according to the temperature of the CPU and thus the noise level remains at an absolute minimum which qualifies it as a silent cooler.

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.
