Keep in mind they may have more than one Sensor for that. Aka one in-chip and one external either on the outside, or slightly off the side on the Heatsink. If it's in the chip, it either could be a faulty sensor, or the die is running at that. Even then, it should be running within limits. If you look at how hot those chips really are at the core, it would astonish you. What matters is how much you can remove at once.
I have been reading a book that says at the actual transistor level, it's 100-1000x hotter from the electricity doing the switching than you actually see on the Die. the Thermistor only picks up radiated heat from the entire chip. Most likely since you aren't experiencing any crashes, it's one of three things:
It's a bad temp sensor
it's reporting wrong, or the application is reading the data/interpretting it wrong
or it could just plain be the operating temp of it.
The only real way to see is to look up and see if there are any documented specs of the operating specifications on the chip. You may have better luck going to whoever made the chip (whether it's TI, Agere (that's what's in my G4) or whatnot. That's about as good of a guess you are going to get.
Frankly, I wouldn't get worried unless the machine crashes, or smokes itself. in any event, replacing the heatsink grease, making sure air flows well and whatnot is the best you can do. if it is a faulty chip, there's nothing you can do until it goes out and decide whether to replace the board or not.
Just enjoy the iMac as it is, I have not to this date heard anything about the chipsets being bad on those. Only the Capacitors.
I have a question, does anyone know if the G5 had an internal memory controller every? Or was that their POWER4 Chips that had that (The POWER4 is what the G5 was based off of, right?)
