Re: How come my 12" PowerBook's fan is always on?
Mine is a 1.33GHz. The Automatic setting would throttle the CPU in low use times for more power savings. The High Performance setting turns off CPU throttling.
Yes it would always absolutely depend on what's running and the room temperature. It's is normal for the fan to turn off and on at anytime.
The iTunes visualizer turns my fan on always, also anything 3D will. World of Warcraft will max the fan out easily anytime it's running. Compiling software will, anything that taxes the CPU will turn on the fan.
Most desktop computers have a fan that runs all the time. Throttling fans such as those in the PowerBook are used to save battery power and noise by only running when they have to, and they pretty much have to if your doing anything on the computer. At least this way when the computer is idle you don't hear a fan like on most desktops.
So I guess what I'm trying to say is just because you hear a fan, it doesn't mean something is 'too hot' or something is wrong, that is normal operation.
