MacBook Pro 16" 2021 Heat Sink Replacement
Introduction
Use this guide to replace the heat sink in your MacBook Pro 16" 2021.
Replacing the heat sink requires you to remove the entire logic board.
***For your safety, discharge the battery below 25% before disassembling your MacBook.*** This reduces the risk of fire if the battery is accidentally damaged during the repair. If your battery is swollen, [[What to do with a swollen battery|take appropriate precautions|new_window=true]].
You will need replacement thermal paste to complete this repair.
Conclusion
***To reassemble your device, follow these instructions in reverse order.***
Compare your new replacement part to the original part—you may need to transfer remaining components or remove adhesive backings from the new part before you install it.
