My 1.8 ghz PPC iMac G5 Overheating?

My hubby got me this iMac, and I swear, it's been in on the repair bench more times than I can count. Luckily, most of it was under warranty. But I was just wondering, if anyone here's got the same system (or knows someone that does) and has 'modded' it to run cooler?

Current Operating System: OSX 10.4.11

Those things are famous for blown capacitors. There isn't much you can do to cool them down except make sure all air vents and fans are clean and try to operate it in the coolest environment you can find for it. I had one in the shop that I even tried to put new thermal paste on the processor to cool it down, but it didn't seem to make much difference.
 
I have a revision B iMac G5 2.0 GHz. Had the logic board and PSU replaced twice in one year. So far, it's been stable, but yes the iMac G5s always ran hot. I would imagine that the iSight model runs even hotter since it was thinner compared to the first two revisions.

I haven't tried any modding to mine, but it's something I might consider down the road. The only problem is dealing with the already-cramped space inside.
 
My CPU temperature averages at 60 degrees celsius. And you can easily feel how hot the plastic gets in a certain area under my monitor. It's frustrating, because I'm paranoid about the thing failing on me again so soon. I constantly back up my info. Also, I love my PPC...and I'm not sure about switching to the Intel iMacs. It feels sacrilegious...

Meh, I got over that a long time ago. The Intel Macs were a fine replacement for the PPC legacy starting with the Core Duo. The fact that even a Core 2 Duo Mac mini can smoke the G5 Macs is telling of how good the Core series of processors have been and are. Besides, just because a processor changes doesn't make it any less of a Mac than before. Remember that Macs used to use 68K chips before they went to PowerPC, which regarding the latter was partly an initiative with their once-rival, IBM. Heck, even though Atari STs and Amigas also had 68K processors when the early Macs had them, that didn't make them Macs either.

I might consider moving to an Intel Mac once Snow Leopard has established itself for some time, or at least until Leopard is no longer supported. But for right now, I don't have much of a compelling reason to. :)
