Before installing the heat sink, see our thermal paste guide for instructions on cleaning and preparing the thermal surfaces and applying a new layer of thermal compound onto the CPU and GPU dies.

For the VRAM chips surrounding the GPU, install thermal pads or a thick thermal paste such as K5-PRO, rather than regular thermal paste.

The above-mentioned "thermal surfaces" are as follows:

The CPU

The GPU

The VRAM chips

The heat sink plates

Note that the heat sink does not need new thermal paste. Clean it, but only apply thermal paste to the other surfaces.
