In Figure 9, you can see the backplate for installing the Nepton 140XL on Intel LGA775, LGA1150, LGA1155, LGA1156, and LGA1366 sockets, and all AMD systems. Socket LGA2011 CPUs use the stock backplate.

You also have to attach the two clips to the block. Figure 10 shows the Intel clips installed; there is also a pair of clips for use with AMD processors.

Place the backplate on the solder side of the motherboard and place the four spacers shown in Figure 11 on the component side.

The last step is to install the system inside the computer, attaching the block on the CPU using four nuts and the radiator on the top panel. We installed both the fans outside blowing outwards.

One interesting thing is that the screws that hold the fans (and also hold the radiator at the case) are all thumbscrews, which we never saw before.
