The cooler is fastened through the mainboard, so you have to take the latter out of the system case to install it on any of the supported platforms. But first you should secure an appropriate mounting frame to the cooler’s base with four screws.

Then use the included key, plastic spacers and nuts to fasten the cooler to the mainboard.
Unfortunately, the kit doesn’t include a back-plate and the mainboard bends noticeably as you are tightening the nuts.
