my g4 runs at 80 degrees!!!!!!!!!!!!!!!!!! celcius

Yes there is, and I hope you have a chassis fan - your system components are not going to last very long at that temperature.
holy cow... that's HOT!
you might want to put a few fans on that thing!
otherwise, i am not aware on how to test the sensor to see if its working... maybe put it in a freezer and see if it goes down to zero?
(DO NOT DO THAT, IT'S A BAD IDEA)

Sell your stove and put a few fans in that thing! When you need to cook, just take out the fans and there you go - boiling water!!! 
(almost - I know it boils at 100 C...)

I think I said °C...Hector said:
Read some of the specs for Motorola chips, they are either 85°C or 105°C.
The newest chips have a Tj (junction temp) of 85°C.

°C can stand for centigrade and celcius it is all very confusing the moto pdf is in faranhight
why can't we all just use Kelvin
I just ordered some srctic silver and will be getting proper copper plates soon (even my revised ones were bodge jobs)

I see them like this... Tj = Junction Temp (Max) (°C)
Which is on the PPC product page spec though it limits the top speed -- as we saw between the iMac and the PowerMac.

Speaking of heat, my mirror door G4 1.25 keeps freezing up (think OS9) lately. It happens at any time using any program or no program at all. I installed an ATI 9800 Pro about a month ago, but otherwise everything else is original.
We've had some warmer weather here and I'm starting to wonder if it's the heat because when it's cooler in the room, the computer is fine.
Is there an on board thermometer that I can use? How are you all figuring out the temps inside?

Fahrenheit. It's Fahrenheit.
Also the junction temperature might be higher than the temperature when you touch (would you want to do that with the heatsink on or off?) the processor?
Do you have a specially made g4 cube, because apple does not make a standard Dual processor cube
but i would see something about it, it can mean two things
1) the heatsink failed and needs to be replaced
2) the G4 Core is aged and has overloaded
Replacement is about all i can think of
but good luck
try replacing the heatsink first

Well, I got fed up and just stuck a portable fan in front of the tower and tilted it so it would be blowing into the intake spots. Crazy as it sounds, my computer hasn't locked up in hours. Hopefully this isn't a "Lisa's anti-tiger rock" situation.
the silicon stuff they put between processor and heatsink might just have been dried for some reason, and it should be ok if you just put in new silicon. so take the heatsink off, brush the stuff away from both the heatsink and processor, apply new silicon on top of cpu and press the heatsink in place. be sure you have silicon everywhere between the cpu and the heatsink, but don't let it flow over onto the motherboard. and don't touch the silicon with your own skin.

you can look at the spec operating temps.

So clearly, from the Motorola specs the 7447a is designed to be running at temps of 85 degrees Celsius. So what is the problem. Remember we are talking about the temperature of the processor itself not the temperature of the air around it or the temperature of the outside case (which is why you would not be burned by a laptop with a processor hot enough to boil water in it).
If the temperature of the air in the computer was 85 degrees Celsius. There would be more of a concern.
I think gist of this is that if your processor is running at these temps... all is well.
BTW, here is a good site about why Centigrade and Celsius mean the same thing.
ps. How are people typing in the degree symbol?

On Mac OS X, [alt]+[0], like so: º
This is using a British keyboard, but on macs I'm not so sure that this is so hugely different to the North American one.
