Apple's factory thermal compound—both the quality and the application—is awful. I feel like my rMBP could seriously benefit from some new Arctic compound on the CPU die (and GPU die, if that's possible). Is it worthwhile to do, though? The machine technically runs fine, even if it could run cooler with some new paste. What have your experiences been with replacing the thermal paste in MacBook Pros? —Thanks P.S. the reason I am considering it is because Slo-jave has started making this computer pretty hot, and I'm sure that it all compromises battery life. If it's not too much trouble to replace the thermal paste, I may give it a shot—even given nothing is technically broken—unless it's more of a risk than it's worth.
