    • Apply the paste on the CPU's very carefully, you don't want certain thermal pastes on electrical circuits.

    • Your paste needs to be distributed evenly on the whole metal cap of the CPU.

    • Reverse engineer this guide to put the laptop back together.

    • Let the paste settle in by letting the computer run for a few consecutive hours.

    • Run a temperature monitor software to check if your application has been effective or not. After a day or two, you may want to stress-test it by running some high end application all together and monitor the temperature.
