I picked up a Supermicro X11SSH-F board for a new NAS build, paired with an E3-1270 v5, and bought a Noctua NH-L12S to cool it. I was getting everything ready when I realized the CPU backplate on the Supermicro board is not removable, and that heat sink requires the included backplate due to its mounting system. I was going through Supermicro's compatibility matrix (Supermicro X11SSH-F | Motherboard Compatibility | Noctua Compatibility Centre) and saw the NH-D9DX i4 3U listed as incompatible, but it mentioned their NM-i115x-1200 mounting-kit, making me think this CPU heatsink will work, provided I also purchase that mounting kit (I know I can get it for free, but I'm in a hurry and it's only $10 on Amazon). Can anyone confirm this will actually work, and if not, what I might need to do instead to make it work? Or possibly just a good alternative quiet CPU cooler that will just mount on the factory CPU back plate?
