Followed the instructions and it worked until next reboot, then the CPU fan
jumped up to ~3000 rpm's. I went back to using the atk0110 again.
I have computed the CPU fan with @/32,32*@ and the chassis fan with @/8,8*@,
seams to give relatively correct figures. Tried using the set fanN_div
statement to get correct min values but I get an error when running sensors
afterwards. Any recommendations on that?

Thanks
Anders
