Now that the old CPU cooler is removed and everything is clean, it’s time to move on to the next step: applying thermal paste.


Step 4: Applying thermal paste

Applying thermal paste is a critical step in ensuring proper heat transfer between the CPU and the new cooler. Thermal paste fills in any microscopic gaps between the two surfaces, allowing for optimal thermal conductivity. Follow these steps to apply thermal paste correctly:

  1. Prepare the thermal paste: Before applying thermal paste, ensure that both the CPU and the new cooler are clean and dry. Squeeze a small pea-sized dot of thermal paste onto the center of the CPU surface. Be careful not to use too much as it can lead to poor heat transfer.
  2. Spread the paste: Gently spread the thermal paste using a clean plastic card or the spatula provided with the paste. Ensure that the paste covers the entire surface of the CPU but remains in a thin and even layer. Avoid applying excessive pressure or smearing the paste beyond the CPU’s outer edges.
  3. Align the new CPU cooler: Position the new cooler above the CPU, aligning the mounting holes or screws with those of the CPU socket. Lower the cooler onto the CPU, allowing the thermal paste to make contact with the CPU surface.
  4. Secure the cooler: Once the CPU cooler is in position, carefully align the screws or mounting clips with the corresponding holes on the motherboard. Gently tighten the screws, alternating between each screw in a diagonal pattern, to ensure even pressure and an optimal fit.
  5. Do not overtighten: Be cautious not to overtighten the screws, as this can lead to damage to the CPU or motherboard. Tighten the screws until they are snug, but avoid excessive force.

By following these steps, you will have successfully applied thermal paste to ensure efficient heat transfer between your CPU and the cooler. Remember, the goal is to create a thin and even layer of thermal paste for optimal performance.

Now that the thermal paste is applied, it’s time to move on to the next step: installing the new CPU cooler.


Step 5: Installing the new CPU cooler

With the thermal paste applied, it’s time to install the new CPU cooler. Proper installation ensures secure and efficient cooling of your CPU. Follow these steps to correctly install the new CPU cooler:
