Thinkfan is a tool to control noise and temperatures of your Thinkpad by setting custom fancurves
Install thinkfan from voidrepo
sudo xbps-install thinkfan
Then edit /etc/thinkfan.conf
and tweak temparatures and levels your liking
Load the thinkpad_acpi kernel module at boot
sudo touch /etc/modprobe.d/thinkpad_acpi.conf
sudo vim /etc/modprobe.d/thinkpad_acpi.conf
->options thinkpad_acpi experimental=1 fancontrol=1
Now thinkfan should work. You can test by "sudo thinkfan -n" to see the output.
This is a very powerful tool so you should keep an eye on temparatures in the first moments.
sudo xbps-install lm_sensors
"sensors" - to check temparatures
To enable the service permanently
sudo ln -s /etc/sv/thinkfan /var/service/
