Thinkfan installation (P14s)

Note: The number and names of the sensors may differ between Lenovo notebook models. They must be adapted for the respective notebook model. The present configuration is for a Lenovo P14s notebook.

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

7. Check, if the service is running, by typing

       systemctl status thinkfan.service

   It should respond: active (running)

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 3-7 from Arch Linux. Keep in mind, that the hwmon settings may differ between Arch Linux and Ubuntu.

thinkfan's Issues

Add information to check the status

run: systemctl status thinkfan.service

Sensors fix T430

Thinkpad T430 workaround:

This .conf file will work:

sensors:

hwmon: /sys/class/hwmon
name: thinkpad
indices: [1]

hwmon: /sys/class/hwmon
name: coretemp
indices: [1]

fans:

tpacpi: /proc/acpi/ibm/fan
levels:

[0, 0, 40]
[1, 38, 45]
[2, 42, 50]
[3, 47, 55]
[4, 52, 60]
[5, 57, 65]
[6, 60, 72]
[7, 70, 82]
["level full-speed", 77, 32767]
