Thinkpad Fan Control with Ubuntu 10.4

Sommer. Hot. You want to turn the fan speed up to keep your precious CPU, GPU, … as cool as possible. If you own a thinkpad, that is quite easy:

To enable fan control on a Thinkpad, the module parameter fan_control=1 must be given to thinkpad-acpi:
sudo gvim /etc/modprobe.d/options and add the line options thinkpad_acpi fan_control=1.

Having done so, reboot and you can use the following commands to control fan speed:

  • # sudo echo level 0 > /proc/acpi/ibm/fan (fan off)
  • # sudo echo level 2 > /proc/acpi/ibm/fan (low speed)
  • # sudo echo level 4 > /proc/acpi/ibm/fan (medium speed)
  • # sudo echo level 7 > /proc/acpi/ibm/fan (maximum speed)
  • # sudo echo level auto > /proc/acpi/ibm/fan (automatic - default)
  • # sudo echo level disengaged > /proc/acpi/ibm/fan (disengaged)
