A 1.5 model.]]> http://www.dslreports.com/forum/remark,16164090 Wed, 24 May 2006 17:08:13 EDT http://www.dslreports.com/forum/remark,16163774 rexbinary : Do you mean which model has the lowest temperature when idle?

If so then it would probably be the model with the lowest clock speed processor as the heat sinks are probably similar due to the similar sizes of the cases.

Or do you mean which one turns on the fan the least?

Again that would probably be the lowest clock speed processor.

Of course again that can vary widely depending on software installed and what it is doing, room temperature, age of the computer. It can also vary from one CPU to the next even if they are identical models.

What is it about the heat and fans that concerns you?

that's what what afraid of... noise from HD is NOT a good sign... ]]> http://www.dslreports.com/forum/remark,16163442 Wed, 24 May 2006 15:31:49 EDT http://www.dslreports.com/forum/remark,16163365 rexbinary : Lower left would probably be the hard drive, the fan is generally in the rear center.]]> http://www.dslreports.com/forum/remark,16163365 Wed, 24 May 2006 15:20:16 EDT http://www.dslreports.com/forum/remark,16163337 dan02 : When I got my PB G4 it was very quiet, the fan never kicks in.. after 6 month I hear the noise but I'm not sure it's the fan noise or the HD noise. (I didn't run any other software since the first day I got it) The noise is similar to low speed fan noise and it's on the lower left of the key board..]]> http://www.dslreports.com/forum/remark,16163337 Wed, 24 May 2006 15:16:19 EDT http://www.dslreports.com/forum/remark,16163235 rexbinary : 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.

What would happen with the "slow" setting...what is the speed of the macine on that? 1.5 G, 80 Gig 12" PowerBook.]]> http://www.dslreports.com/forum/remark,16162605 Wed, 24 May 2006 13:25:01 EDT http://www.dslreports.com/forum/remark,16161523 rexbinary : Mine will run most of the time if I have it set to High Performance and I have my door shut to my computer room. Also depends on what you have running, etc.
