Powerbook heat dissipation question

[agusgriego]

I have a question about AluBooks that might as well apply to other 'Books.

Apple recommends to have your Powerbook over a flat surface under heavy use.
What's best?
To have it over a flat surface and let that surface act as a heat dissipator (i'm guessing there is more surface for the heat to dissipate but also once the surface gets hot below the powerbook nothing cools it),

or to have the powerbook "suspended" and let air pass beneath it?

Thanks in advance for the replies,

I don't think it really matters. But to be on the safe side, I elevate my Powerbook, by resting the back on a book so that there is some air flow.

They recommend using the PowerBook on a flat surface (like a table) as opposed to your lap or a pillow so that air can circulate underneath. The reason the case feels warm is because aluminum is an excellent conductor of heat; essentially the case is one big heat sink. If you're real concerned about it you can get a stand with a couple of fans built in to keep things nice and cool. Hope this helps.
