Powerbook Fans, always on?

What kind of surface is it sitting on?

Try turning down the performance a little. Maybe tht will help.

I have a 12" 867Mhz and don't have that kind of fan issue.

you're pushing twice the horsepower I am, so that may contribute.

Try lifiting it up a little to give some cooling to the bottom. I've used a couple of CD cases when my 15" would get too hot.

Are all 4 little rubber feet in place?

The powering through USB could definitely be the problem. Do you always leave this drive on? Maybe try only using it when needed.

Are you running Tiger? I've discovered it's Core Image and it's pretty intensive use of the GPU that kicks my fans on all the time. You don't have to be doing much to get the heat up. I just bought a laptop cooling pad with fans and that keeps them off 90% of the time unless I'm doing something really GPU intensive.

Along the same lines, I feel like my fans are more prone to become active since I've updated to the newest version of 10.4 through Software Update. Can anyone else confirm this?

I don't know about fans being more active, but I have noticed mine running a little hotter since then. strange.

I was actually thinking of asking this same exact question, but you beat me to it. I have had the same problem with my PowerBook ever since I connected my external drive via USB 2.0. I also have my PowerBook hooked up to me Dell 20.1" widescreen display so that's definitely using up resources.

I guess what I am wondering is... is there a way to fix this? I know it's not really a problem, but rather a minor annoyance. I actually just got an iCurve, but I am waiting for my Apple Bluetooth Keyboard to arrive in the mail before I actually use it. Do you think using my iCurve will allow my PowerBook to circulate air much easier and cause less fans to power on? Obviously it will help a little... but how much?

Sorry for kind of hijacking your thread, brikeh. I figured it was related, so why not take a stab.

Isn't there a Temperature monitor available for/in Tiger?

how much fan noise use are we talking here?

My 12'' PB the fan always runs, no matter what you are doing. Now its not running full bore, but it is running and you can hear it.

Now when I plug in a 20'' ACD, then the fans get going full throttle.

So if its just running a fan, thats normal, if its running full throttle fans all the time, than that may be due to the USB HD, not sure.

Do you know off a 10.3.9 version?

I would be more concerned if it wasn't running, youll burn out you computer faster.

I have a fan issue that I've posted about in this thread.

Mine is a 15" albook though.

I just bought a 12" PB too, and I have noticed the fans much more than on my iBook. They are usually constantly on and tend to kick in a bit stronger every now and then just using safari, adium, and iTunes.

I think this is just because they are stronger computers than the iBooks. The processor is faster, better graphics card, 2x the harddrive, etc.

My fans on my 12inch 1.5ghz pb never come on?
I have usually only adium, mail, safari running.. but even when i have safari, mail,adium,itunes,word,notes,azerus,limewire pro running it never comes on either.. so im not sure why your guys fans are always on.. my palm rest can get warm here and there, but never to hot where i can't rest them on there.. idk
