Hey guys, I am building a cheap server for a project, and I can't seem to get the right CPU coolers.

The motherboard is a Dual Xeon e5-26xxx compatible Asus Z9PA-D8: https://www.nix.ru/autocatalog/motherboards_asustek/161373_2245_draft.jpg
These are standard LGA-2011 sockets (I know that LGA-2011, LGA-2011v3, and LGA-2066 are the same physical socket).

I've gotten several LGA-2011 coolers by now, for example: https://gelidsolutions.com/product/rev-5-tranq/, but it seems that all of them require you to install their own backplate. The CPU backplates on this motherboard are not removable. I feel retarded. The main issue is that the screws that come with the coolers are too thin and/or too long, even though the retention mechanism lines up with the screw holes correctly.

My memory is playing tricks on me. Is this because it's a server board?
For example, the screws on this cooler look correct by the shape and relative size: https://www.ebay.com/itm/284658618446, and it specifically says it doesn't come with a backplate.
Other server coolers look correct too: https://www.ebay.com/itm/314677372718.

So what's the deal here? Are there two variants of coolers and motherboards for the LGA-2011 socket? Ones that require their own backplate, and ones that don't? I mean if that's the case, that just seems ridiculous.

Is there a specific cooler I need to look for? I don't feel like paying $80 bucks for a Nactua, but regardless, how would I know if an LGA-2011 cooler is actually compatible?

They may just have sent the wrong screws, or you are supposed to screw in an interposer fastener.

The hyper 212 for example, makes you add custom screws first that fit into the backplate, and then you screw the cooler into them.

Take some photos maybe? Any manual(s) with the cooler should have explicit instructions. Maybe post that? Is there a bag of unknown screws that you missed? Check the packaging?

Apparently, it's the wrong screws. And then their support said "Sorry this cooler isn't really compatible with LGA 2011, here buy this more expensive one" :)

lol. At least support told you one useful thing. Any hope getting the right screws?

Yeah, so even though the 2011 pattern was out for a long time, I think I encountered about a 2% spawn rate in real life (I think I had maybe 15 boards ever (in 12 years)). Sorta makes sense that pattern's screws aren't included with everything. (to give them reasonable doubt)

Still, sweet system, chip, price, and always impressive power. Really get to use all the capabilities of the platform.
I love how many sticks of ram you can stuff in x99 boards for instance. Aesthetically.
