As title states. Just decided to take pics and post em up for fun. Took about 20 minutes and I replaced the stock crap of a thermal paste with some quality Arctic Silver 5. Immediate drops in temps ranging from 10 to 25C. There was a lot of gunk ontop and around the chips--an elephant could've done a better job. My recommendation: reapply it if you're temps are reaching over 85C like mine were doing youtube/megavideos/hdplayback and getting stuttering every so often.. It voids the warranty, but who's to know? Just don't screw up anything in the process. I'm here to help anyone who wishes to do this. Items: Arctic Silver 5 Thermal Paste $8.99 70-90% Rubbing Alcohol 5-15 Q-tips Plastic card (I used guitar picks) to evenly apply the paste Steady and calm hands. Unscrew the bottom aluminum. It should be 6 very smalls, 2 smalls, and 2 not so smaller than the rests =]. You will immediately see the heatsink. There should be 6 (or 4 I forgot) screws to remove, remove the L arm, and just lift it off. Just look up the forums on disassembly. 1) Look at the crappy job they've done. You can't see it in the pictures, but it was terrible. 2 cm high wall of china style thermal application that surrounded the 9400chip and intelchip. 2) Dab Qtip into Alc, not too much. Then proceed to gently clean and remove the thermal paste. Clean it off the chips, around the chips carefully, and from the bottom of the heatsink. 3) Apply the new arctic 5 paste. Don't apply a rice grain. That is for the desktop cpus. I applied 1/3 the size of rice on these smaller chips. Spread them evenly. 4) Reassemble and see the immediate drops in temps! Wait for a month to burn in the new thermal paste and see another 3-8C drop. I'm actually at work typing this up so it's very vague lol. Ask, and I'll try to answer/help. The pic of applying the thermal paste evenly shows a crappy job of doing it. I did it over a couple times to get it smooth, just don't have the pictures for it. Also, this can be done at an apple service center but costs up to $110 if you don't manage to convince them to put it under apple warranty coverage.
