Step 1: Prepare the surface

Before applying thermal paste, it’s important to ensure that the surface of the CPU and the heat sink are clean and free from any debris or old thermal paste residue. Here’s how to prepare the surface for optimal thermal paste application:

Gather the necessary tools: You will need isopropyl alcohol, lint-free cloth or coffee filters, and cotton swabs.
Power off and unplug the computer: Before beginning the process, make sure to turn off the computer and unplug it from the power source to prevent any accidents or damage.
Remove the heat sink: Carefully remove the heat sink from the CPU by loosening the screws or clips holding it in place. Refer to the manufacturer’s instructions if necessary.
Clean the surfaces: Dampen the lint-free cloth or coffee filter with isopropyl alcohol and gently wipe the surface of the CPU and the heat sink to remove any residual thermal paste or debris. It’s important to be gentle and avoid applying too much pressure.
Inspect for cleanliness: After cleaning, inspect both surfaces to ensure they are free from any residue or debris. If needed, use cotton swabs dipped in isopropyl alcohol to clean hard-to-reach areas.
Allow surfaces to dry: Give both the CPU and the heat sink enough time to air dry completely. This will ensure that no moisture remains on the surfaces before applying the thermal paste.

By properly preparing the surface, you can ensure that the thermal paste will make good contact with both the CPU and the heat sink, allowing for efficient heat transfer and optimal performance.

Step 2: Apply the thermal paste

Before applying the thermal paste, make sure that both the CPU and the heat sink are clean and free from any dust or debris. Use a lint-free cloth or isopropyl alcohol to clean the surfaces.

Take a small amount of thermal paste, about the size of a pea, and place it in the center of the CPU. Avoid applying too much paste, as it can lead to poor heat transfer.
Use a plastic card or a spatula to spread the thermal paste evenly over the surface of the CPU. Make sure to cover the entire surface, but be careful not to spread it too thin.
