Step 4: Install Computer Processor (CPU)and Heat Sink/Fan Assembly
Install Computer Processor (CPU):
In this tutorial, we are using an Athlon 64 X2 Socket 939 CPU.
You can view my Cheap Computer CPU Guide here.
Processors (CPUs) are delicate components so handle them gently.
To install the CPU, lift the lever on the socket straight up to the open position, then properly align processor with socket and carefully insert, taking care not to bend any pins.
Install the computer processor (CPU) into the socket, taking care not to bend any pins.
The CPU should just drop into the socket without any resistance. This socket is called a Zero Insertion Force (ZIF) socket.
Diagram A below displays the computer processor (CPU) and socket.

Ensure that the CPU is sitting properly in the socket and then lock the lever back down. (See Diagram B below). Diagram B also shows the ZIF socket lever being lowered.
Install the Heat Sink/Fan Assembly:
After the installation of the processor (CPU), install the heat sink/fan assembly.
If the heat sink came with a thermal pad or tape on it, you do not need to use thermal compound. In the event that it does not come with a thermal pad or tape, you need to use thermal compound due to its low electrical conductivity and good heat transfer properties.
Apply a small amount (but sufficient) to the core of the processor (CPU). Use enough to cover the core but not too much that it spills all over the CPU and motherboard. (See Diagram C below).
To install the heat sink/fan assembly, start by placing the fan flat against the CPU and clip one side of the heat sink/fan assembly to the socket.
Clip the other side with a screwdriver to secure. Keep the heat sink flat on the processor (CPU) - not at an angle. EXERCISE EXTREME CAUTON - It is extremely easy to damage CPUs while installing the heat sink/fan assembly. (See Diagram D below).
Please note an anti-static wrist strap being worn. This strap will help to protect your computer components from static electricity damage. Click here to read my article and learn more about Static Electricity.
You have now installed the heat sink/fan assembly. Plug the fan into its appropriately marked header (CPU1) on the motherboard.
