any thoughts on why cooling fan keeps spinning up and down?

[Robert L Cochran]

I think there is probably a physical cause. It gets too easy to blame 
the operating system for physical device issues. The fan speed is 
controlled in part by temperature sensors on the CPU and feedback from 
the fan circuit itself. I think all the fan speed controls are managed 
by motherboard parts, not by the operating system interacting with those 
parts.
