Here you can report problems, results, exhaust air temperatures (and possible methods of detection) concerning the G4 Mac minis. The original HOT MINI? topic itself was becoming a bit cluttered and veering off from its primary focus, so before it becomes another multi-paged, diluted juggernaut, here’s an attempted offshoot. I hope this helps to keep things a bit more clear and to also provide help to others.
There’s also another related topic dealing primarily with Hot Mini (GPU Thermal Pads) here:

Now, we’ll see if I can successfully split posts from one spot to another. And if not, well then this attempt will simply be nuked and I’ll begin again. But for now, if there are posts above this one…
Maybe I had some success?
(Well not completely, this was to be the first explanatory post under this new topic heading.)
Anyway, please take a bit of time and record your mini’s Exhaust Air Temperature and whether you detected any increase in your fan’s speed (within the first 10 minutes after a cold boot). And then post your results, comments and any questions under this topic.
You might just save your mini - or help someone else to preserve theirs for another TWENTY YEARS!
Thank you.

(And quite nice to hear from ol' DieHard again too.)
