Arctic's
Alpine AM4 Passive is designed for AMD's 35W desktop processors but looks amazing paired with Intel's Bean Canyon NUC. We're curious to know how mounting works here, though.

Update: "
What I did: use the existing mounting holes of the mainboard: 95mm in one direction, 90,50mm in the other direction apart from another. Arctic AM4 passive has 99x99mm, so I just drilled 4 1,5mm holes in the appropriate places, threaded 2M threads into each hole and screwed the AM4 from the bottom. Heat is transferred via a thin copper plate which is glued to the stock heatsink and from there via standard thermal grease to the bottom of the cooler." (Thanks Parke!)
