Use this guide to replace the thermal paste in your Mac mini (2024).

This guide was written with a baseline M4 Mac mini. Although the internals for the M4 Pro version are slightly different, the disassembly procedure is the same.

The thermal paste in your Mac mini will deteriorate over time and might affect your processor's performance. This guide shows how to replace the thermal paste to keep your Mac mini running smoothly.

You need to replace the thermal paste every time you remove the heat sink. This guide doubles as a heat sink replacement.
