I took an Xacto knife and cut/pried off the feet on my 12" PB. Then I Superglued the feet for a TiBook on it (in the same sockets).

It's worked very well, lowering the temps substantially by lifting the unit a couple more mm above my work surface. Of course, if you're using an iCurve or some such device all the time this mod is useless. But it should keep your machine running cooler if you use your PB on a flat surface.

nice one! and since the original feet tend to fall off anyway ... ;-)

seriously, though. a friend let me use his 12" powerbook at a party last weekend. the place was pretty packed and i ended up having it on my lap for quite a while. i was worried it would get hot and BURN! but it's definitely not the scorcher people like to make it out to be ... but then again, i'm in canada and we had our last snowfall a little over a week ago ;-)

needless to say i'm ordering my 12" today.

You an edmontoner?
hehe

Yeah I'm thinking I won't have to worry about heat to much the dorms at college will probably be cold anyway, so I can just use it as a space heater... I actually seriously use my iMac for that in the winter, I close the door and let it run for an hour and my room is noticably warmer than the rest of the basement... I sometimes loveably call him my iSpace Heater.

yeah edmonton crew represent, and all that. woke up to a foot of snow on my car a little over a week ago. nice ...

brings up an interesting point, though. how well do powerbooks respond to cold? i'll be walking to university with mine every day next winter and it would not be unreasonable to expect some days at -30 degrees celcius. is it gonna freeze and die? how will the aluminum deal with cold?

Just don't try to lick it when it's cold outside.

Oh yeah, extremely low temperatures wouldn't be good for your hard drive and optical drive, but if your machine's sleeping, I wouldn't anticipate a problem.

fldsfslmn: Assuming you don't store your PowerBook in the garage overnight at minus 30 deg C, the only thing you have to worry about is condensation. Condensation can form inside your PowerBook when you go from the cold outside to the (relatively) hot inside. Such condensation is especially troublesome if it forms inside your HDD, for example. If you want to avoid all trouble, you theoretically have to let your PowerBook slowly warm to room temperature before waking it from sleep.

But that's all theory. In practice you should be just fine.

yes the powerbook seems a tough little customer. the ibook's all-white plastic had me a little nervous -- mainly because a polar bear might think it was her cub and try to chase me!

no, not really, but i know plastic doesn't always cope with extreme temperatures very well.
