Take a look at the P4 LGA 775 datasheet
pages 76=>78.
If I don't misunderstand, at different power demand correspond a different temperature limit...

Do I have to connect the multimeter in series with the core to get the absorption?

Those 63° could be good or not, I can't know.

In the hope this can be usefull for anyone else.

I've found solution by this free utility
ThrottleWatch (www.panopsys.com).
It shows CPU work freq and Thermal Throttling activity in real time.
