What kind of material to use?
Unfortunatly folks the heatsink wasn't designed to clamp down onto the cpu like a normal heatsink should do, as it has to cover several different gpu/memory chips of different sizes, making a small gap between the heatsink and cpu.
I've heard of people using a square or even round piece of steel or copper or something to wedge in with some thermal paste. Well, all I can think of off hand to use that might work is some sheet metal that has some white paint or something coated on one side, and a round steel (?) rod out of an old printer that's been sitting around. I presume the latter would probably be better.
Can someone suggest what would be best? Should I try cutting it with a hack saw or try getting someone's bandsaw so I can get a better cut? Right now my ibook is reporting a cpu temp of 53 of Celcious, which really, compared to when it's turned on from a cold start, is really F***** slow and very laggy, it often hangs for minutes at a time. It's horrible to use sometimes, but at the same time it owes me absolutely nothing so I won't cry if it burns out.
