I had a problem with my fan speed running very high so I decided to open my MBP up and check on my fans. I took apart the fan and the Airport card to see what if anything is going wrong. after taking both apart I put them back together and re screwed everything. Once I turn my MBP on the fan speed was still running at a very high speed and my Airport card says Not Installed. Can someone help me out here? Will my warranty replace my airport card if for some reason it just stopped working when I opened it?
