    Except for the MDDs, there are no software accessible sensors in the G4 processor.

     

    One sure way to help cooling is to remove the old, baked out thermal pad and apply new thermal compound.

    Use Arctic Cooling MX-3 or MX-4 for safe, high performance thermal conductivity.

    I have found that the best temperature sensor for the G4 Quicksilver is your hand - placed gently on the processor heat sink. The dual processor models tend to run hot, and if your hand finds the heat sink too hot to hold onto, you may want to fit a slightly more powerful CPU fan such as the Evercool EC6025H12CA from

    Price is c.$6.95 +s&h, and fitting it requires replacing the stock fan inside the small black cooling shroud (several Phillips head screws) pushing the blue third wire out of the way and reversing the red and black wires in the connector that connects to the two pins on the motherboard. (This gets the ground right.)  A small pick or other small sharp pointed object - even a paperclip - is helpful.

     

    Cools it right down. I never needed it on my 933MHz QS, but my dual 1GHz seems grateful.

     

    You may also want to hold your hand behind the power supply vent just over the power cord from time to time to get a baseline on how warm your Mac is running.

     

    By all means replace the thermal compound as Japamac recommends, and blow out the dust bunnies on a regular basis.

     

    A cool Mac is a happy Mac!

    Heat has nothing to do with performance. They have the same computational power at 100*c as they do at 0*c.

     

    Your G4's CPU will operate fine upto 100*c before thermal management activates self-protection (kernel panic or turning off the computer).
