Incorrect. Please reference Derek Martin's previous post in this thread,
where he mentions how Linux idles the CPU when it is not busy, and my previous
post, where I talk about how I've witnessed this first-hand with temperature
probes.
CPU heat output is *far* from constant.

Yes, but the point is, if the fan is connected to fan headers on a
motherboard, then most likely, the motherboard can control and monitor fan
speed. As opposed to when the fans are just connected to a drive power lead,
running full blast all the time.
