Failure to remove the old paste and apply a new layer can cause the computer to overheat and sustain damage. The following steps refer to replacing the thermal paste between the processor and heat sink; follow these steps only when you are ready to place the logic board in the computer.

  • Use a firm plastic edge to scrape the thermal material off the processor.

  • Apply a new layer of thermal paste to the copper heat conduit.

  • When replacing the logic board, make sure all cables are routed around and above - not under - it, and to connect the two cables that do go beneath before pushing the board into place.

  • Place the logic board back in the computer, trying not to move it around once the processor has come into contact with the newly-applied thermal paste.

you can also use nail polish remover to get the last of the thermal paste off.
