It is generally a good thing that a processor turns itself off before it burns itself to death. This way your computer isn't destroying itself just because of overheating. Once you've got the overheat problem fixed, you'll still have two good processors. > I know it needs cleaning, and I've > attempted to clean it several times in the past.

If you want to remove all the parts in your way to clean it, you may start here: http://www.powerbookmedic.com/mac-repair.php They have very good video tutorials for disassembling the whole G5. To assemble it back together just go reverse… http://www.powerbookmedic.com/manual.php?id=53 You can find a lot of tutorials on YouTube too. Disassembling and putting it all together again is what I would do first. > I'll admit that I don't know much... that's rather obvious, but can someone > address my issues? Thank you. It could well be a corrosion problem as well. http://www.xlr8yourmac.com/systems/G5_coolant_leaks.html After you've looked inside and checked out all the parts, cleaned them, and put them back together at least you know where is no obvious problem inside, like leakage or dust. If the processors are constantly overheating, you should propably also take a closer look at the processor unit with the liquid cooling part on it. It can be various things that make the processor overheat: the liquid pump can be broken. If this is the case, it will not transport the liquid to the restrainer. It could be an electrical problem, like a loose connector. Or the cooling unit can be leaky (worst case). I hope that helped. I wish you good luck with your “Quad” G5.
