Thinkfan installation

Arch Linux

1. Install thinkfan (AUR) and lm_sensors. Note that the thinkfan package installs /usr/lib/modprobe.d/thinkpad_acpi.conf, which contains

   options thinkpad_acpi fan_control=1
   

   So fan control is enabled by default.

2. Now, load the module by typing:

   modprobe thinkpad_acpi

   cat /proc/acpi/ibm/fan

3. Check, if the hwmon exists used in the thinkfan.conf exists. /sys/class/hwmon may have [email protected] monitor directories. To check if the hwmon exists cat /hwmon@x/name. The number of indices is can be read by checkin how many tempx*_input* and tempx*_label* file exists.

4. Change the hwmon settings in the thinkfan.conf if necessary. Afterwards copy the thinkfan.conf to /etc/thinkfan.conf

   sudo cp thinkfan.conf /etc/thinkfan.conf

5. Configure thinkfan to use the newly created file

   echo 'THINKFAN_ARGS="-c /etc/thinkfan.conf"' | sudo tee -a /etc/default/thinkfan

6. Finally, enable the thinkfan.service by typing

   sudo systemctl enable thinkfan.service

   sudo systemctl start thinkfan.service

Ubuntu

1. Enable fan control

   echo 'options thinkpad_acpi fan_control=1' | sudo tee /lib/modprobe.d/thinkpad_acpi.conf

2. Install thinkfan package

   sudo apt install thinkfan

3. do steps 3-6 from Arch Linux. Keep in mind, that the hwmon settings may differ between Arch Linux and Ubuntu.
