First post. Just had to replace the logic board on my PMG4 DP 1.25GHz machine. For the life of me, I can't remember the operating temperature before I swapped the board. Currently it's running at 130F - 140F. This seem about right for the other folks running these machines?
Got a tip for us?

I have a G4 1 ghz Dual MDD (same fan and aluminium heatsink as 1.25 ghz) as a second machine. The machine would idle at about 54 C (129 F) and the beefy fan would kick in from 58 C (136 F). Remember that the CPUs in these DP G4s don't cycle down during idle unless you use Apple C.H.U.D. tool and enable Nap mode. This will allow the machine to idle at arround 40 C (104 F) and run quieter. Hope this answers your question
The duals tend to run hot; since replacing my sing 1.1 with a dual 1.3, it's noticeably hotter, so much so that I don't need the heater under my desk anymore. Not a big deal, but if you're worried, look into extra fan options (add one blowing on the heat sink or a PCI slot exhaust fan).
jobooth321, those temps appear to be just about how hot my PowerMac MDD runs. I don't think you have anything to worry about.
Great to hear!jobooth321 said:
I am still fighting a much slower G4 500 (SP) processor swap in a B&W. The thing is always running hot, despite me having a CPU fan on a CPU that shouldn't need one!
