Ok, but aren't they some guys asking for solutions for problems they have?
As it is my case and with my (quite long) experience of boards, I thought it would be kind to announce that my problem was resolved before they have to read the entire topic to the end.

Lot of boards have this feature.

I ...

What do you mean? I just posted it on other forums where guys tried it and it seems to work.
Ok for the status, I just don't want to bore people finding a solution if it's solved, am I wrong?... Just wanted to be kind, but that's not obvious.

Thanks anyway.

how can I indicate that the problem is solved on the main topic?...

YES !!! After 3 hours running ASD test the computer returned no error and lost almost 20°C when idling, and even with Safari, CS4 (Ps, Il, Fl, Id open), it works !!! It certainly had a bad setting in temp sensors that was cleaned.

Thank you for your help !

Ok, thanks, waiting for the tests to end... They seem to be good so far.

I'm actually running ASD 2.5.8, I'm waiting for the results (long long test...)
Would severe hardware failure permit the machine to start up and run anyway?

If the one of the CPUs was dead, I think the computer wouldn't even start up or would be very slow.

Hi Turboladdade,

of course I'm reading Celsius Temps!...

Normal temps for idling are about 40°C - 50°C (104°F - 122°F) on these machines.

Thanks anyway...

Hi everybody,

I recently was given an old 2x1.8Ghz PPC G5 in order to build a personnal server but I have troubleshooting with CPU's temps that are really too hot (75°C with no app open, only Finder).

I know these temps are not that "hot" but I can't imagine what it would be when I'll open Safari ...
