Hello folks,
I'm having a difficult time trying to figure out why the CPU cooling
fans run at full speed on my Supermicro X8DAL-3 motherboard. There
doesn't seem to be any variable speed (the fans are PWM compatible) ...
they either idle at almost nothing, or suddenly burst into a
high-pitched scream that gets my ears bleeding after a few seconds.
Once they jump to warp-10, they remain there.
The "Super-I/O" chip on this board is a Winbond W83627DHG which does the
temperature and voltage monitoring.
Is anyone aware of which driver or kernel module I need for that chip in
order to get control of the fans? The Supermicro web site and the
board's manual aren't any help. Fresh installs of CentOS-5.5 and RHEL-6
don't exert any control by default. Installing the lm_sensors package
and probing with the 'sensors' command didn't help either.
Slowly going deaf .......
Chuck
