Can I control the CPU fan speed

[ozgta]

Hi,
Is it possible to control the speed of the CPU fan in my desktop computer?
The CPU runs cool at 30C yet the fan sits around 2700rpm and the BIOS doesn't allow for speed control.

Package: fancontrol

Version: 1:3.1.2-6

Description: utilities to read temperature/voltage/fan sensors
 Lm-sensors is a hardware health monitoring package for Linux. It allows you to
 access information from temperature, voltage, and fan speed sensors. It works
 with most newer systems. 
 
 This package contains a daemon that calculates fan speeds from temperatures and
 sets the corresponding PWM outputs to the computed values.

thanks sjukfan,
If I understand correctly lm-sensors and fancontrol need to need installed (which tehy are) and the fan control will be automatically controlled.
Ihave lsb-base (>=3.2-13) installed however I unsure what the following quote means,

Conflicts: lm-sensors (< 1:3.1.1-6)
Replaces: lm-sensors (< 1:3.1.1-6)

I guess lm-sensors need to remain installed?

however I unsure what the following quote means,

Conflicts: lm-sensors (< 1:3.1.1-6)
Replaces: lm-sensors (< 1:3.1.1-6)

It just means that it won't work with lm-sensors earlier than version 1:3.1.1-6, and if an earlier version where installed it would be upgraded to the latest.

Have a look here https://wiki.archlinux.org/index.php/Fan_Speed_Control for how to config fanspeed.

OK
thanks again sjukfan
