In Figure 9, you can see the backplate for installing the H75 on Intel socket LGA775, LGA1150, LGA1155, LGA1156, and LGA1366 systems, with slideable nuts. Socket LGA2011 and AMD CPUs use the stock backplate.
Place the backplate on the solder side of the motherboard and screw the four spacers shown in Figure 10 on the component side.
As we mentioned before, the block comes with the holder frame for use with Intel CPUs preinstalled. If you will use the H75 on an AMD processor, you must remove this frame and fit the AMD one to the block.
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 rear panel. We installed both the fans outside blowing outwards.
