The installation of the Cooler Master TPC 812 is simple. First, install the scissor-like clip over the base of the cooler, as shown in Figure 11. This clip comes with the screws that will hold the cooler in place.
The second step is to install the screws shown in Figure 12. Just insert the screws from the component side, put the backplate on the solder side of the motherboard, and then install four nuts that secure everything in place.
Apply the thermal compound, put the cooler in place, and fasten the four screws.
The last step is easy: install the fan in place.
