FAND - a fan controller hack

CAVEAT

This code is experimental and my break your hardware. Use at your own risk!

What is this?

This is a small hack for my laptop. It uses the FreeBSD acpi_ibm and coretemp modules to throttle the fan level according to the core temperatures (using a very basic algorithm).

Why was it written?

The fan of my laptop tends to refuse to throttle down, even when the cpu cores are rather cool. This tool fixes this issue.

And to be honest I was curious how to do this.

TODO

  • Logging
  • The thresholds for the fan levels have to be fine tuned.
