cpu temperature overhead when using compiz

[guillem]

When compiz is activated, the PC stops running suddenly and I must wait because the CPU temperature is over the threshold. My PC is:
Chipset: Intel dual core 64 bit.
Nvidia: Nvidia geforce 6 series (restricted driver).

I have had before Edgy with Beryl activated without any problems. Furthermore, when I don't use compiz, the PC runs OK!

 I've seen that I have the same problem running ubuntu without running compiz and It's not a hardware problem because I have also güindous XP installed and I haven't had this problem yet.
It's strange, but sometimes works fine and sometimes not, and It's not a question of which software is running (but I believe is something about how "many " process are running).

Compiz simply exposes the problem, this is a problem with the power/thermal management.

Do you have some idea how to solve it? Or some way to limit it?

Bug resolt. It was the fan!!
It's quite strange but probably ubuntu heats more the cpu than windows XP.
