One of the things that you can do to help your machine along would be to clear out the vents in the case. A can of compressed air, available at all good computer shops, will clear them out and ensure an adequate airflow.
I'm not sure of the optimum running temperature for the PowerBook G4 but I'm pretty sure that the temps you are seeing are fairly normal.
I am currently running an iMac, it's doing nothing to tax the processors and the CPU temp is 101F.
Your fans are almost certainly running, you just can't hear them
I just did a little Googling and found that you have nothing unusual in your G4 temps. Some of them run at 140 on a regular basis. No wonder you never hear the fans, you running that thing in a freezer? ![]()

I have a Powerbook G4 Running 10.4.11. Until recently i was not aware that it had fans. I can't recall ever hearing them run. Using iStat nano i normally see temp ranges from 70-80 deg.F. I have seen it go above 100 deg. F.
I have come across a utility called G4FanControl that lets the temp. at which the fans come on be adjusted. My question is, are the temps i'm seeing normal for this machine or should i consider using the utility to run the fans more? I guess i'm of the mindset as far as computers/electrtonics are concerned, heat kills. I am quite happy with my Powerbook and would like to make it last.
Thanks for any input.
