Critical Temperature Problem

[Gary Jarrel]

My notebook is a HP NW8000 and the compatibility between it and Ubuntu
is phenomenal. It's been running fine for over a year, on Warty, Hoary
and now Breezy. The system is alot cooler than it normally is, and has
not been sitting in the live installation for about an hour and a half
(I haven't been using it though).

I don't think it's the fan at all, The system would have gotten a lot
hotter if the fan would have stopped or even slowed down. I would
assume if the temperature sensor has just died, then a live
installation wouldn't boot either. I've tried the live install on
another desktop before with a slow fan and it reached critical
temperature before gdm loaded.

I would suspect that it's some service, but then again it's been right
for a year or so. I'll have to make use of my air compressor just in
case.
