My 867mhz 12" PB is driving me nuts since I went to 10.3.8. You wake it up, spend about 2 minutes using Safari and as Steve would say, BOOM! the fan goes mad. It never used to do this. I know the 12" runs hot, especially the first version like mine, but surely this is over the top? Or do you think Apple are worried there's a long-term heat issue that may cause them problems in the future? Perhaps they're ramping the fans up with each update to protect themselves?
When I first bought the PB I was so chuffed at how quiet it was, and didn't even realise it had a fan. It now sounds like a wind tunnel...

Maybe it is time to clean up inside of your powerbook. Accumulated dust inside the powerbook prevents flow of air and makes the fan running even with low usage of CPU.

That sounds a bit scary! How much of a disassembly would it need?
Actually when I'm running on battery it switches to lower performance and then it never does it. I might try switching my powered setting to reduced and see what happens.

Could you just stick a hose vacuum to the vent ports? I'm just guessing. This does sound scary...

first thing you may want to do is get a temperature monitor to see if your comp (cpu or video card) is running hot or not... if it is you may want to take a look at the cpu usage of all open applications... sometimes, an overly active program can make the cpu or even video card run hot causing the fan to stay on... if you can't isolate a program or if the temp isn't all that high, then you likely have a calibration/sensitivity prob with the fan which could be hardware or software based... p.s. i'm far from a computer expert, but i thought the above ideas may be of assistance...

Yes, I support that.
The gpu gets hot very quickly. If you have some animated ad zapping around in your Safari window it can be a matter of 2 minutes until the gpu has more than 60C/140F.
