x62-fancontrol
Small tool to set the fan speed of x62 laptops from 51nb. This was written analyzing the windows utility available at https://forum.51nb.com/forum.php?mod=attachment&aid=MjI3ODAzNHwzYjcyMmUxMnwxNTA2NDU1NTQyfDE4MjEwMDh8MTY4OTMzNg%3D%3D.
Use at your own risk, obviously.
Usage:
$ sudo apt-get install libpci3 libpci-dev # or equivalent on your system
$ make
$ sudo ./x62-fancontrol
In every command below we'll fail with error code 2 in
the case of unexpected data from an IO port, which is
useful since this seems to happen after a resume.
x62-fancontrol temp
Displays the current temperature.
x62-fancontrol set-fan-speed <fan-speed>
Sets the current fan speed. The EC will kick back in after
a few seconds.
x62-fancontrol manager
Manages the fan speed for you.
I'm not sure yet what the fan speed numbers represent.

A wrapper script that automatically restarts on expected failures after
resumes is provided, x62-fancontrol-manager.py.
I currently run it using a simple systemd service file:
