I set HZ to 100 in include/asm-i386/param.h but still my CPU goes to
62 degrees in stead of 46. But it does not go to 80 degrees, so maybe my
problem was another than yours (although it is the same make and model -
strange).

It is on a vanilla 2.6.7 kernel, and I did no patch on it.

I have a feeling that it may be because the kernel want to set it in C2
and that the machine only supports C2 - but this is a totally
unresearched hinch.
