Introduction

You will learn how to remove and replace the computer's heat sink. This will require an extensive teardown of the keyboard's internals. You will be removing the motherboard, SD card slot, USB ports, and other internals. Make sure you have a secure place to store the tiny screws you will be removing.

The heat sink transfers heat from the graphics card and motherboard to the fan, ensuring that your computer doesn't overheat. If this heat sink is damaged and not replaced, you run the risk of permanent damage to your motherboard and graphics card by overheating.
