Fan keeps running

Unless you have more information than what you report, this is normal. The fan runs continuously and always has. It will only stop running if the computer is put to sleep or turned off.

My Black Macbook started doing this in the last week, I think it might coincide with with a recent X update. I downloaded a third party software package that lets you control your fan speed, mine won't respond and only stays at max RPM. Anybody else seeing this problem?

Check Activity Monitor. Quit anything that looks to be sucking up a lot of CPU power.

Actually, I was wrong upon reboot the application I downloaded took over. My computer is now running at 2400rpm w/ a temp of 113F. Do a search for smcfancontrol 2.1.2.

thanks,

Same problem here - and it is definitely since the recent installation of sys and iTunes updates. I've had it for 6 months and this is a definite change in behavior.
On Activity Monitor I see that the Macbook is running at an average of about 66% activity - the same OS with the same applications open on my Mac Mini (a slower non-intel machine) seems to average around 20% activity.
A bunch of people have reported finding a CPU hog - usually Print Manager or Quick Look - in Activity Monitor. Killing that process seems to help.
Firefox and Mail seem to be the big differences for me with both of them using a huge amount of CPU - 50 something and 95 somethings respectively. On the PowerPC machine Firefox is about 7 and Mail is 0.2!
Hmmm.
Any suggestions out there?
It is whirring away!

Hey, my macbook just started whirring away too... i'm not doing anything out of the ordinary, (i did install a new update too though)..... there's not a lot of usage in the CPU either...
the constant whirring is NEW. the constant whirring is annoying and distracting.
MALadaptive behavior!
WHY?? why now? usually before it would be off and on whirring.... help?
tawn

I'm running Firefox 3 Beta, and I've found that it gradually picks up more and more CPU usage, but a simple quit and restart fixes it for a while.

i used activity monitor and found 3 print jobs using 95.0+ cpu each.
my fan calmed down as i was quitting them.
i also quit some stuff from root, so i hope it wasn't important.
i either fixed it, or ruined something.

any advice is welcome.

thanks

i was just having the same problem for the last few days and I just quit firefox to fix it immediately. apparently it was using all the CPU power

I've got the same problem as well, but in Activity Monitor it's mds and Finder being my massive junkies. I don't even start anything, other than the computer up. Dashboard and any programs I get into are fine, it only takes forever to open windows.

I can't even quit these darn things to fix this.

I fixed this by dumping my preferences folder, then adding them slowly back. In the end, the ones I had left didn't make sense, and it suddenly happened again, so I decided to screw the prefs and it's dandy now.
