Every once in a while, my eMachines fan kicks up, kind of like the cooling
fan on a car engine, even after the car is turned off. I figure it's the
same thing. Either there is an extra fan that kicks in when the case temp
goes up, or there is a two speed fan. At least that has always been my
assumption. Could I be wrong?
It has done this since the unit was new and I don't have any operational
issues. Insight?

Hard drives and fans generally run at a constant speed, and so their
noise
tends to be constant too. This "rev up" sounds like what some machines I've
worked with do in order to determine what CD/DVD (or, occasionally, floppy)
is in a drive.
