Why Is My Power Mac G5 So Hot? Really. It Is HOT!
This new PowerMac G5 is one hot machine. And it runs fast, too. It’s remarkable that such a cool looking device runs as hot as it does. Thank IBM for those new 90nm PowerPC chips. Whew.
What’s different about this PowerMac G5 is that the chips are cooled by a liquid cooling system; a radiator with coolant. Just like your car. Chips are so hot these days (AMD, Intel, IBM) that new cooling methods had to be introduced.
The first PowerMac G5s had all kinds of fans and.... (excerpted).

Odd. I have a ‘new to me’ G5 dual 2.3 Ghz. It has the following temps, according to IStat menus (which is, to me, btw, seriously cooler than Temp Monitor)
• Main Logic Board Backside = 105.1 degrees F
• CPU “A” Die Temperature = 141.1 degrees F
• Processor Card A Ambient = 109 degrees F
• CPU “B” Die Temperature = 132 degrees F
• Processor Card B Ambient = 104 degrees F
• Drive Bay (dual SATA HDs) = 75 degrees F
• U3 Heatsink = 149 degrees F
• Drive1WD = 105 degrees F
• Drive2Hitachi = 92 degrees F
I wonder if I need to reign in the CPU a temp. Temp Monitor reads it as being set at a max limit of 168 F. Is that too high?
Note that I give not a damn about fans running. So far this is much, much quieter than the G4 quicksilver I worked to death.
