I was looking at this Asus motherboard with KT333 chipset: asus.com
Among the features is this:

ASUS C.O.P (CPU Overheating Protection)

ASUS C.O.P (CPU Overheating Protection) is a hardware protection circuit that automatically shuts down the system power before temperatures go high enough to permanently damage your CPU.


Finally. But this is the interesting part:

ASUS Q-Fan

Constant, high-pitched noise generated from heatsink fans are a thing of the past thanks to ASUS Q-Fan™. The ASUS A7V333 with Q-Fan™ technology intelligently adjusts fan speeds according to system loading to ensure quiet, cool and efficient operation.


My assumption is that they are increasing and decreasing voltage on the 12V line going to the fan, based on the CPU temperature, but it is only my assumption. There is nothing in the manual, and I have not found any comments about it in any newsgroups.
