Hey guys, sorry I posted this question earlier but I never really got a reply. My question is as the title states but to elaborate I want to change the thermal paste with my friend whose done it plenty of times before and I trust his skill in replacing the TP once I get my MBP. I am doing so because I have heard MBPs just run a lot better and cooler with a fresh coat of well applied paste. BUT if I had to take it into Apple for any odd reason down the road, would they be able to spot that I had re-did the paste and thus void my warranty? I'm not sure how they would test this as long as I didnt carve my initials into the CPU or something stupid like that but I thought it was worth asking.
