# echo level 4 | sudo tee /proc/acpi/ibm/fan (medium speed) # echo level 2 | sudo tee /proc/acpi/ibm/fan (low speed) # echo level 0 | sudo tee /proc/acpi/ibm/fan (fan off) If you receive a PERMISSION DENIED error you can use the following command syntax instead as a work-around: # echo level disengaged > /proc/acpi/ibm/fan (disengaged) # echo level auto > /proc/acpi/ibm/fan (automatic - default) # echo level 7 > /proc/acpi/ibm/fan (maximum speed) # echo level 4 > /proc/acpi/ibm/fan (medium speed) # echo level 2 > /proc/acpi/ibm/fan (low speed) # echo level 0 > /proc/acpi/ibm/fan (fan off) Having done so, reboot and you can use the following commands to control fan speed: To enable fan control, the module parameter fan_control=1 must be given to thinkpad-acpi.įor example, in Ubuntu 8.04 (Hardy Heron), add the following to /etc/modprobe.d/options: options thinkpad_acpi fan_control=1įor Debian Squeeze (testing) create /etc/modprobe.d/thinkpad_nf with: options thinkpad_acpi fan_control=1 and install the package thinkfan Fan control operations are disabled by default for safety reasons.
