Figures 10 and 11 show the installation of the holder frame on the motherboard. You must put the backplate on the solder side of the motherboard, and then attach the four thumbscrews from the component side. Afterwards, put the metal bars (each one has a screw at the center) in place, securing them with thumbnuts.
Then, put the cooler in place, holding it with a transversal bar.
The last step is to install the fan, as shown in Figure 13.
