Applying heatsink compound (thermal paste) is a critical step in ensuring proper heat transfer between a processor (CPU or GPU) and the heatsink. Here’s a method I use for applying it:

Materials:

Thermal paste

Isopropyl alcohol (90% or higher) and a lint-free cloth (for cleaning)

Heatsink

CPU or GPU

Gloves (optional)

Step-by-Step Method

Prepare the Surface:

Clean the surface of both the CPU/GPU and the heatsink with isopropyl alcohol to remove any old thermal paste or debris. Use a lint-free cloth or paper to prevent any fibers from contaminating the surfaces. Choose the Application Method: The goal is to apply an even, thin layer of thermal paste. I usually use the small dot or pea-sized method because it’s simple and effective.

Small Dot/Pea-Sized Method:

Apply a small dot of thermal paste (about the size of a pea or rice grain) in the center of the CPU or GPU. When the heatsink is pressed down, the paste will spread evenly across the surface.

Mount the Heatsink:

Place the heatsink directly on top of the CPU/GPU. Attach the heatsink mounting bracket or screws without lifting it up again (to avoid creating air bubbles in the thermal paste). Secure the heatsink firmly but evenly.

Check the Spread:

If you're unsure about the application, you can dismount the heatsink after pressing it down to check if the thermal paste has spread evenly. If it has, clean both surfaces and reapply the paste, then remount the heatsink.

This method helps ensure proper thermal conductivity between the processor and the heatsink.
