would anyone agree that it is normal for my "newish" powerbook to get hot (almost to hot to hold my hand on it) on the bottom after just an hour or so of use...is this normal or should i be concerned?

thanks

It depends what your are doing when it gets hot. mine gets almost too hot when I've been doing video edting for a while and the computer is set to highest performance.

If i play Halo or Black & White for too long (30mins or so) my 15" gets almost too hot to touch on the bottom. If i run Temperature Monitor the processor gets up to about 61.8 C (143.2F) before the fan goes on full power then it drops down to about 59C (138.2F) before it turns back off again. As long as the bottom is aerated then im sure the computer can handle it because mine just oscillates between these temperatures.

Personally after seeing the tread on this forum about using wire paper trays as laptop stands, i went and "acquired" one of the cheap plastic covered steel variety and stood on it a bit so the laptop was angled down and that seems to help, or at least makes me feel better about it!!

The Alu case is very heat-conductive, so it will feel very hot when the PB cpu gets hot, but it dissipates the heat quickly. As long as your fans kick in when the PB gets hot you're OK. I also try to keep the back of the case elevated to allow more air to pass under, and it can get very hot as well.
Manual says operating temperature : 50 to 95°F / 10 to 35°C
So as long as the room your in isn't over 95°F / 35°C ...

you guys should always be careful to raise the back a little when you're doing processor intensive stuff. I didn't with my pbook 550 and I couldn't understand why my hard drives kept failing (I'm on my fifth). the processor isn't the only component that can get damaged.

I could just be imagining it but when my PB gets really hot underneath, if you blow on it a bit ( like a lung-full) then that area gets noticeable cooler for a few seconds...demonstrates the thermal conductivity quite well, plus it makes me chuckle thinking of the number of people who will now be blowing on there Laptops!!!

Yea, that does help a little. When my left fan (the noisy one) kicks in, I sometimes blow air into the space between the LCD and keyboard, and can actually hear the fan spinning faster ... and see a quick but small temp drop. But I think that if you can provide the underside of your PB with fresh circulating air, the temps would differ, and would be a little lower.
