How to build your own PC? - Motherboard, heatsink and case. The CPU heatsink is next, make sure the fan is working by rotating it a couple of times with your finger, or simply blow against it to make it spin.
Also make sure the heatsink either has a thermal interface pad mounted or comes with heatsink paste. Simply place the heatsink on the CPU and push one side of the heatsink clip, in our case the left side, down to secure one side of the heatsink to the socket. Fig 6. The heatsink mounted on the CPU, notice the heatsink clip is secured to the socket on one side. Now align the heatsink so that it sits flat and level on the CPU-die, making sure it isn’t tilted and push the other side of the heatsink clip down so that the heatsink is secured in place.
