In Figure 9, you can see the backplate for use on Intel CPUs. You must insert the four nuts into the backplate before attaching it to the solder side of the motherboard.
The second step of the installation is a little complicated. You must mount the frame on the block, as shown in Figure 10.
The last step is to install the system inside the computer, attaching the block on the CPU and the radiator on the rear panel, on the space originally designed for the rear fan. You must remove the rear fan of the case, if your case has one. Both fans must be installed as exhaust.
