I used this guide plus the Thermal Paste guide to resolve my MacBook RRS (Random Restart Syndrome) issue. My MacBook would randomly restart after the fan kicked into high speed. When I removed the heatsink I discovered an an irregular patch completely free of thermal compound of about 15-20% of the area on one of the processors. I removed and re-applied the thermal paste. I ran a memory test utility overnight that previously caused a restart after a couple of hours, and the probelm seems to be solved. TIme will tell.
