My cooling fan runs constantly, on high speed. The system is not overheating— it is blowing cool air.
It's an older unit, but has done this for a long time. Note:
- It has recently been cleaned and has a new hard drive with a clean intall of its OS
- The bios item "run fan constantly when plugged in" is unchecked
- The fan actually runs constantly whether plugged in or not.
I beleive the issue must be a failed thermostat, but I don't know where that is— is it embedded in the processors?
The computer is running beautifully, does what I need, and I can't afford a new one now. But if the thermal unit is in the processors, I believe replacing them (and motherboard?) would be more that the unit is worth. Is there any work-around? Perhaps an aftermarket thermal unit? Or is the existing thermal unit external to the processors and possible to replace by itself?

Have you updated BIOS to latest version:
Thermostat is not spared separately.
Fan,heat sink assembly or motherboard (BIOS) may be at fault here. Since there is no overheating at all, BIOS may be the culprit.

So, the new BIOS is installed, with no problems. Probably should have been done long ago anyway.
Unfortunately it did not solve the problem. I guess at this point, we have to assume it's a hardware issue, and given the age of the computer, one I'll just have to live with.
Thanks again. —nick
