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, take appropriate precautions.
You will need replacement thermal paste to complete this repair.

I respectfully disagree with the difficulty rating of “moderate”. Having to remove the motherboard in any Mac is never a moderate procedure. Perhaps for someone familiar with all those tiny connectors, it’s not overly difficult. But for anyone who hasn’t done such an intricate and complicated task, it’s asking for trouble. One tiny mistake, and you’re screwed!
For me, this is yet another reason not to buy a modern MacBook. The older Retina MacBooks require only a few screws and parts to be removed in order to change the thermal paste. The procedure shown here reminds me of the much older MacBook designs. The ones requiring almost total disassembly for the simple task of replacing thermal paste.
By requiring such a complicated procedure, Apple is virtually guaranteeing a limited lifespan. Your average person would never consider such a complicated task, and I’m certain Apple (and others) charge hundreds of dollars for what should be a simple procedure. This is a textbook example of “planned obsolescence”. 🤬
