Introduction
Follow this guide to replace the thermal pad covering the APU.
The Honeywell thermal phase change interface material (the thermal pad) shouldn't dry out and need to be replaced by itself. However, if you need to remove or replace the heatsink, you can follow this guide to apply a new thermal pad.
