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.

this is another problem i started having with the test version, and
it's still happening now -- on my gateway laptop running fully-updated
f11, the cooling fan keeps spinning up and down with about a 3-second
period. it's really kind of annoying. occasionally, it will stop
completely for a bit, then it starts oscillating all over again.
thoughts?

Actually, modern notebooks (and probably most desktops) have their fan
controlled by the ACPI "thermal zone" driver - strictly software. Saves
the manufacturers a few cents on every motherboard.
