Figure 12 shows the backplate for use with AMD and Intel processors. The threaded holes on the “Intel side” are compatible with sockets LGA775, LGA1155, LGA1156, and LGA1366 CPUs. Socket LGA2011 systems will use the stock mounting system, and AMD systems use the other side of the backplate.
Put the backplate on the solder side of the motherboard and screw four spacers (shown in Figure 13) by the component side. Then, install the two bars shown in Figure 14.
Then, install the heatsink over the CPU, holding it with two nuts and a transversal bar.
Finally, install the fan.
