Hello,
I did a few things during the weekend on my laptop, as upgrading the kernel
and cleaning the fans.
First, I upgraded the kernel from 2.6.20-15 to 2.6.20-16 then I shut the
computer down in order to clean it (I know, I should have done it
separately...). It has quite a lot of dirt into the fans and heatsinks (my
laptop is 2 years old). I removed it all using a can of compressed air, and
I added some thermal paste on the CPU core (the original thermal paste
wasn't too visible, I think Dell put a very thin layer of thermal paste
originally).
When I booted the computer, the idle temperature was much lower, around 35C
(instead of 50C). Putting it into "performance" mode did increase the
temperature, but not as much as before. The fans are quieter too. Since the
kernel upgrade was a security fix (correct me if I'm wrong), I think that
cleaning my laptop solved the problem.
I could compile a custom 2.6.21.3 kernel without rebooting (the temperature
was around 65C IIRC). Using that kernel, the situation is similar: the
temperature is much cooler than it was before I clean my laptop. Therefore,
I do not think that the kernel is the main problem in the scenario.
Though, I believe that there may be something strange (but not broken) with
the temperature reporting since it is increasing/
may be the hardware that is desined that way though, I did not try on
Windows (on a separate hard disk that I use about once a year) to see if the
behavior is similar -- I'll add it to my TODO list.
Could other people with this problem clean their machines to see if it
helps?

I totally agree with you, Len!
