My fan works fine by itself now (Thinkpad X31), but I recall needing to use the command

echo 3 > /proc/acpi/[SOMEPATH]/fan

on Etch as root to turn my fan off when it became stuck on full after suspending. I could also use values from 0-3 to set it to different speeds.

I now use Lenny and the fan file has a slightly different path and more detailed content, e.g.:

status:         enabled
speed:          0
level:          auto

However, now I find I can't write to this file directly, even as root, who supposedly has write permissions! This I don't get.

Do you need help?

Anyhow, if you can find your /proc/acpi/.../fan file, see what's in it and change the value of the fan speed (if you can write to it), that may work.
