Hello! This is my first post here so excuse me I have a refurbished macBook Pro and everything was working fine (it's about 9 months old). So everything was fine till suddenly the right fan started making these horrible noises. Kinda like a motor boat along with with ticking clanking sounds. It comes and goes: also Istat shows that the max RPM is 3000 or so. Thinking something was stuck in the fan I figured i'd take the back cover off to take a look, and now I have stripped one of the outer screws holding the back cover. Now i'm worried my warranty is void, even though the fan issue was not my fault but the stripped screw is. I plan on going to the apple store soon to see what they say but I was curious as to what you guys think first. Will the apple store fix the screw and then replace that fan?
