I remember that back in 2006 a lot of the Core Duo-based laptops (one of which I had) had some truly horrible thermal paste application jobs done, and that this (along with silicon-based compound) contributed to the overheating problems that some users experienced. My question is this: do 4th gen MacBooks suffer from this? I've got an early 2008 MacBook (identifier: MacBook4,1 -- the last of the BlackBooks), and I'm debating whether or not to try to redo the application with Arctic Silver. Needless to say, I don't want to strip down the machine if there's no need, so I was wondering if anyone here knows if this generation has the same issue (or if it even uses thermal compound...) Any input is appreciated. P.S. I don't have any serious heat concerns, but I'd like to get the laptop as cool as possible. It idles at around 49-53C with the fans @ 1600RPM. It's undervolted: 1200 and below @ 0.95V, 1400/1700 @ 0.965V, 1900 @ 0.975V, 2100 @ 0.9875V, and 2400 @ 1.0625V.
