In Figure 11, you can see the clip and the backplate for installing the A50 on Intel processors. It is a very simple system, and you first need to install the backplate on the solder side of the motherboard. Then you need to attach the clip to the base, as shown in Figure 12. In some coolers with a similar clip design, the clip remains loose over the base. Screwing the clip to the base makes the installation easier and more reliable. Finally, put the cooler over the CPU and screw four thumbnuts. Simple, easy and reliable.
After that, you need to install the fan, which is a very easy task, because the fan comes installed on a frame, and all you need to do is to snap it to the heatsink.
In Figure 13, you can see the Corsair A50 instaled in our case, with the fan in place.
