Just got off the phone with my brother, an Apple genius. I asked if he'd like to crack my MBP open and reapply the paste. He said, and I quote, "NO! Just update the firmware, there's no problem with the thermal paste." But it's pretty obvious there is (or was?) some overzealous pasting going down. How can a firmware update fix an abundance of grease? I'm guessing it increases fan activity, but won't that diminish battery life even more? Now I'm a bit worried about opening it myself, because I'll never hear the end of it if I screw up.
