Hey Guys, After getting some advice from forums and other areas I decided to change the thermal paste on my Retina Macbook Pro. I ran into a problem while putting it back together. I am really unsure how it happened but for some reason one of the holes, near the hinge and vent in the back has stripped. The screw now fits in but does not turn and pops out very easily. I think the threads on the inside have somehow become damaged. My question to you guys is, is there a way to fix this? I have included some photos the best I can. The second question is, the computer seems to still be hot. It sits on my desk and normally idles around 45-50c. The air temperature in the room is about 25c. If I am doing absolutely zero on the computer it can be high 30's or low 40's but as soon as I do something it jumps to 50. Watching flash puts it somewhere between 60-70. Playing games is in the 80's but the fans spin up to about 6000 rpm. I just want to make sure these temperatures are fine and that nothing is going to happen to my Mac. I don't want my Mac do die any sooner than absolutely necessary. Thanks in advance for the help.
