[QUOTE="pigoo3, post: 1027406, member: 56379"] I know that you said that you did some cleaning of the inside of your G5...but some of the hardest areas to clean may be the areas causing the most restriction to air flow. For example any sort of "finned" cooling heatsinks...and any or all of the cooling fans...could be clogged with "fuzz". Another thought could be...the G5 computers have a lot of fans in them. One or more of your fans could have "died" (I believe your G5 has 9 nine fans)...causing the remaining fans to work overtime to cool the computer. So verifying that all fans work could help figure things out. Lastly...your Quad G5 (in addition to the cooling fans)...has a liquid cooling system for the processors. It is not unheard of for blockages to occur in the liquid cooling system...which can cause overheating as well. Sometimes the liquid cooling system even leaks coolant. - Nick [/QUOTE]
