Cool down a PB G4 15'?

Just for reference: THIS is a HOT Mac.
iMac G5 17" iSight. I'm constantly scared by those temperatures to the point where my GPU solder points actually failed twice and needed a reflow, and they'll need another one soon I guess.

And the Mac has been powered on only a few minutes ago. The GPU will reach 80°C+ at idle, and 85°C+ when watching videos etc.
I already replaced the thermal paste on the GPU twice, no difference.

Yeah, this had me concerned too when I first got my own iMac G5. Turns out that 150-170º plus is a normal range for the G5 iMacs. I looked it up because it scared the hell out of me.

It was on 24/7 a few months back though and zero issues.

Which model is it?
The pre-iSight ones are hotter than the later ones and don't have any GPU issue. The iSight model does...
It's been on for 3 days and no issues, I will reflow it again when it dies

I'm glad I have a pre-iSight then.

It's a 20" non-iSight Mac.
