@adminmat , to clarify if you want to try it with the Hyper 212: I used the LGA 2011 screws provided with the cooler and threaded them into the socket assembly. I put the fold-able bracket into the "AMD" configuration. Then, I spread the bracket open a bit more and slid the fixing screws in their slots until they lined up with the threaded holes in the top of the mounting screws on the socket assembly. The center pivot won't be locked at this point (it will be between two locking holes), and some of the fixing screws may be between the locking "detent" positions in their slots. Hope that made sense? Anyway, because the components aren't "locked" in, it gives it a less firm feel in my opinion.
If you're thinking of using a Hyper 212, I assume you're not running a server and are needing point cooling for a desktop style case? If so, I've had a few desktop style systems at home with Narrow 2011 sockets and found that, other than server oriented gear, there's very little selection. So, here's what I've tried myself:
1. Concerning the liquid cooling option that
@RageBone mentions: For AIO liquid coolers that use the Asetek mounting system, Asetek sells a mounting kit for Narrow 2011 sockets. If you aren't familiar, many manufacturers use the Asetek mounting system, so you aren't locked in to Asetek branded coolers. I'm using one of these mounting kits with a Corsair H55 Cooler on a Supermicro X9DRT-F with no issues. If Asetek shows out of stock, you can email to them to ask for more. I've done that twice now, and they've restocked when I requested it. I don't think these are in high demand at this point, so I think they only reorder from their suppliers when people ask. As far as I know, this is the only ready-to-use liquid cooling solution for Narrow 2011 that's still available. If somebody else knows of something else, I hope they chime in!

As for other options:
2. Dynatron makes a 2U cooler, with a small fan, but it sounds like a 747 on takeoff.
3. Lots of passive heatsink options for server use. If you've got a desktop case, its possible to use a server style 1U or 2U passive heatsink along with a cooling fan. I've used Supermicro SNK-P0057PS, which have open fins at the top, along with a 92 MM Fan on top for downdraft, and it worked fairly well with low wattage CPUs.
4. For another machine with dual 95 watt CPUs, I printed 3D printed brackets to let me use off the shelf air coolers with the AMD clip-on style mounting:
