Thermal paste is a crucial component in heat transfer between the CPU and the cooler. It helps fill in microscopic gaps and ensures efficient heat dissipation, preventing the CPU from overheating. In this step, we’ll guide you through the process of applying thermal paste correctly.

Start by cleaning the surface of the CPU and the base of the CPU cooler using isopropyl alcohol and a lint-free cloth. This step is crucial to remove any dirt, debris, or residue that could affect the performance of the thermal paste.

Next, locate the small tube of thermal paste that usually comes with the CPU cooler. Squeeze a pea-sized dot of thermal paste onto the center of the CPU. It might seem like a small amount, but remember that thermal paste spreads out when pressure is applied.

Using a plastic spreader or the cooler’s included applicator, carefully spread the thermal paste in a thin, even layer across the entire surface of the CPU. Ensure that the paste covers the entire CPU, but avoid applying too much pressure, as it could cause the paste to spill over the sides.

Be cautious not to touch the surface of the CPU or the thermal paste with your fingers, as the oils from your skin can interfere with the heat transfer. If you accidentally touch the surface, clean it again with isopropyl alcohol and a lint-free cloth before proceeding.

Once you have evenly spread the thermal paste, it’s time to move on to the next step: attaching the CPU cooler.


Step 4: Attaching the CPU Cooler

Now that the thermal paste is applied, it’s time to attach the CPU cooler. The CPU cooler plays a crucial role in maintaining the temperature of the CPU by dissipating heat generated during operation. Follow these steps to securely attach the CPU cooler.

Start by identifying the mounting mechanism for your CPU cooler. There are different types, such as brackets, screws, or push-pin designs. Refer to the cooler’s manual to ensure you understand the specific installation method.

Align the cooler’s mounting brackets (or other mounting mechanism) with the corresponding holes on the motherboard. Gently lower the cooler onto the CPU, ensuring that the cooler’s base makes contact with the thermal paste you applied earlier.

If your cooler uses screws, tighten them in a diagonal pattern, gradually and evenly, until secure. Be careful not to overtighten, as it can damage the CPU or motherboard.

If your cooler uses a different mounting mechanism, follow the instructions provided in the manual to secure it in place. Pay attention to any additional requirements, such as securing clips or tightening levers.

Double-check that the cooler is firmly attached and seated evenly on the CPU. Ensure that there is no excessive wobbling or movement. A secure and stable cooler installation is essential for optimal heat dissipation.

Once the CPU cooler is securely attached, you can proceed to the next step: connecting the power supply.


Step 5: Connecting the Power Supply

Now that the CPU cooler is in place, it’s time to connect the power supply to your motherboard. The power supply provides the necessary electricity to all the components, including the CPU.

Locate the 24-pin ATX power connector on your motherboard. The power supply’s main cable has a 24-pin connector that matches the port on the motherboard. Align the connector and firmly push it into place until it clicks. Ensure that it is securely connected and seated properly.

Next, check if your CPU requires additional power connectors. Some CPUs have an additional 4-pin or 8-pin CPU power connector near the socket. Consult your motherboard and CPU manuals to identify the correct connector and its location on the power supply.

Take the appropriate CPU power cable from the power supply and align it with the socket on the motherboard. Carefully connect it by firmly pushing it into the socket. Like the ATX power connector, ensure that it is securely connected and seated correctly.

Double-check all connections to make sure they are properly seated and secure. Loose or improper connections can lead to instability and potentially damage your components.
