PB 12" fan/temperature

Message #1 - Posted 2005/04/20 - Keith Wiley

People have noted for months that the 12" PBs seem to run their fans just about continuously. Having just bought a 12" I can verify this claim.

-) I am not interested in finding ways to turn the fan off, which seems

to be a common desire. My interest is in knowing whether this is indicative of a serious problem with the PB. Sure, they all run the fan all the time, so my computer can't have a unique problem. My question is this: if the fan always runs, doesn't that mean the computer is never "satisfied" with its temperature, that it always thinks it's too hot? If that is the case, does that mean the computer is actually being damaged by being too hot all the time? Or is my computer safe even though the fan is on all the time?

I have Temperature Monitor installed and the main CPU temp can go as high as 140F when I'm running an intensive application. This is with the back end raised up off the desk.

Is that too hot? Is the computer at risk of being damaged? I'm not talking about flipping a bit and crashing the computer, that's just software. I mean, at what temperature do I risk physically harming the commputer?

Thanks.

I had a 12" 867mhz before I bought a 15" 1.33ghz PB and noted the same thing when I had it. It got hot VERY quickly, and almost burned me at times.

Talking to others about this problem I realized it wasnt just me (I thought I had done some fan damage) but a rather large problem. I think that mine was getting so super hot was because it was one of the first (if not the first?) editions of the 12" PB.

You have a lot of computer in a little bit of space, so all heat has to get out STAT. I think that it is rather normal. About upping the CPU, I doubt you are hurting it to much, and judging by how hot my old 12" was getting, I know that didnt get damaged.

What is the temperature of the default?

Don't know what this says about your machine, but the fan on my 12-inch PB rarely runs. It does get pretty warm if I use it in my lap for a while, and the fan sometimes runs then. But not even close to continuously.
