Figure 10 reveals the backplate used to install the CNPS12X on all CPUs except for those with socket LGA2011. You must install the nuts at the backplate in the holes matching the socket used by your CPU.
After putting the backplate on the solder side of the motherboard, you need to attach four thumbscrews from the component side, installing two metal pieces over them, as shown in Figure 11.
After installing the frame, put the cooler over the CPU and hold it in place, screwing the transversal holder to the frame.
All three fans present on the CNPS12X have blue LEDs. Figure 13 shows the cooler turned on.
