The first step of the installation of the Neptwin is to prepare the backplate. You must install the four screws in the holes that match your CPU socket, holding it in place with rubber pieces that also act as insulators. Figure 11 shows the backplate with the screws installed in the socket LGA1155 position.
Locate the backplate in the solder side of the motherboard, install four plastic spacers, and then the metal bars shown in Figure 12, securing them with four nuts.
Put the cooler in, holding it with a transversal bar. Notice that the first fan was located over all of our memory modules.
The last step is to install the second fan, as shown in Figure 14.
