I can heartily agree with this.  The only problem being that not all
Motherboards can do this and not all ones that can are supported!

In any case this worked a treat on my P4 HT 3.6Ghz machine in a crummy
old box that was full of dust with only one extra case fan. Despite
all the dire warnings I set up my config to only turn on the fans
(slowly!) when the CPU hit 60deg. From then on I enjoyed just about
completely silent computing (except the PS fan!) and this was all with
the stock Intel Cooler.

The CPU temp used to hover around 40-50deg at most times, I have been
told that this is bad but then it worked for me for about 2 years no
