My 12" G3 900 Mhz ibook is just over 3 years old, and yesterday for the third time in 3 years the motherboard died. Fortunately, Apple is gonna swap out the board for free even though the warranty expired 2 weeks ago (I think partially why they're doing this is the current motherboard only lasted 5 months and 1 week). I'm starting to wonder if maybe the small form factor and design of the 12" ibook prevents it from cooling efficiently enough to allow the motherboard to survive. Then I thought, if that's the case, maybe I should drill some more holes in the case to get more air moving through it. I have two reservations though: 1) If I do this, and then the new motherboard dies within its 90 day warranty, they might not fix it for free. [I could wait until after the 90 days, but by that time heat may have already shortened the life of the new motherboard] 2) If I put additional holes in the case, I might damage some cables or hardware that lie directly on the other side of the case, where my new hole pokes through. So, I'm wondering if any tech savvy ibook owners around here have done anything like this? Does anyone know where the safe areas might be to add holes? Does anyone think this is a good idea? If the next motherboard only lasts 5 months, I can't imagine Apple would replace it for free again, since then it would be 6 months past the ibook's 3 year warranty. I suppose, since this ibook is mostly used as a desktop machine, an alternative would be to add a tiny external fan. Does anyone know of any other cooling options for a primarily stationary ibook?
