The fan of my brandnew powerbook 12inch will being working after start for about half an hour and won't stop, is it normal?

I feel the temperature on the leftside of trackpad is not high at all. I am wondering whether this powerbook is a fault one.

Anyone has the same problem with the fan? It is quite noisy

What's your Mac sitting on? If it's on a hard surface that will help the heat dissipate through the aluminium case, then the fan is less likely to come on.
If it's sitting on a sofa/cushion/pillow etc, then it will stay on more.

Also what are you doing? Basic websurfing and iTunes and it shouldn't be on all the time. If you're rendering things in iMovie, then it will be on longer. Also check what your processor performance is set at.

The 12" PB's get pretty hot now with Tiger, I think it's Core Image that's causing it, so check the temp on your video card and I think that's where you'll find the culprit for the fans.

I have the Targus Chillpad and it does a good job keeping the fans off most of the time, except during heavy heavy CPU usage.

thanks for your reply. :)

my mac is on the table which is definitely hard surface. And I only do some web surfing indeed +adium+skype+isq, that's all. W.r.t. preocessor performance, it's normal.

Now I returned from dinner, the fan fortunately stopped working after wake from sleep. But I don't know what's going on later. :(

yes, indeed the graphic processor has the highest temperature, 52 C.

Should I turn off coreimage? hehe
