Hello, I just took apart my Macbook Pro Unibody (13 in 2009) and put new thermal paste on. The tear-down was flawless, but upon putting the laptop back together I immediately noticed an issue. At first, the fans ran at 6000RPM immediately under startup, and there is no Airport installed according to Mac OS. I took apart the computer and put it back together again, and this time I had normal fan, until I put any slight amount of pressure on the case which causes it to immediately go to 6000RPM. I did a SMC & PRAM reset, and it solved the no wireless card for a boot cycle. Also, the computer did not shut off, but kept on restarting when I clicked shut down. It turned itself off, and immediately back on. I then performed another teardown today and loosened the screws on the heatsink I believe I may have tightened them too much. Now I kept the screws at a reasonable torque, and put it together again and WIFI showed up for one boot cycle, and then stopped working. The computer shuts off now, but I still have an issue with my fan's turning up to 6000RPM when I have pressure. In addition, I noticed when I put pressure on my case, my CPU, Heatsink B, and Northbridge temperature drop to -128C, while the fan runs at 6000RPM. Does anybody have any ideas for a solution to this problem?
