PE1950 fan speed

[Vernon A. Fort]

I have a PE1950 running gentoo.  During a cpu stress test, we expected 
the fan speed to go up but it did not.  We had the cpuload around 25.0 
and when i put my hand at the back of the server, it was very hot to the 
touch.  I have looked at the lm_sensors and the openipmi but i did not 
find anything related to controlling the fanspeed, i.e. making it go 
faster when under heavy load.

Could someone point me to some good reading.  Basically - i need to 
monitor the server and have something that adjusts accordingly.

Thanks,

Vernon
