This is a write up on how to use
thinkfan on Lenovo ThinkPads running antiX Linux. I am writing from my (bad) experience after installing antiX Grup Yorum 21 on a Lenovo ThinkPad P15s with the fan running constantly at max speed.
This is based on the guide provided at https://gist.github.com/Yatoom/1c80b8afe7fa47a938d3b667ce234559 however since the
thinkfan utility does not seem to be available in the default repos of antiX Linux, it also includes steps to build the utility from source code - plus other tweaks for Thinkpad.
Try installing from repo
$ sudo apt install thinkfan
