My fan keeps spinning - why???

Message #1 - Posted 2004/08/15 - Michael Levin

Hi all. I'm running the latest update of Panther on a 17" G4 laptop. I've noticed in the last few months that the fan is on an awful lot. I don't think it was this way before. Is there any way I can find out why? I have one of those apps which measures CPU temperature and it says 50.3C. Is that high? What's the upper limit on Cpu temperature, anyhow? Is there any way for me to find out what the hell is going
on? This happens while I'm reading email, not burning a DVD or any high-intensity computation. Any thoughts would be appreciated. Thanks!

Maybe you have a background app stuck in full processing mode. Happened to my brother the other day with his 500MHz TiBook. Somehow he had Classic running and it was using all of the available processor time and the fan was running. He stopped Classic and everything went back to normal.

also may not be the fan at all, could be the hard disk not spinning down, the fan is quite loud, the h.d. hums, I get the h.d. to spin down by using Cocktail (do a search on Versiontracker.com)

Type "top -u" at a terminal window or launch the Activity Monitor and see if you can figure out if there's something taking up all the available CPU cycles.

More than a few times with my 12" Powerbook G4 running 10.3.5, I've caught the Finder sneaking away with all available CPU cycles. 0% idle. I still don't know why or how, though it tended to happen when I was processing an iDVD project (and you can imagine how infuriating it is when the Finder starts hogging CPU cycles away from a program that really does need all it can get).

Whenever I see the Finder start to misbehave like that, I force it to relaunch and things cool down after a bit.

got same computer, thought it was the fan, was the hard drive, try Cocktail, setting it to spin down after 1 minute
