Hydro x series help

[TristanG.Arellano]

Hello there I recently learned the hard way that I should really double check my items before hitting buy on Newegg. I bought a x570 board and new ryzen 7 processor to replace my 1st Gen ryzen system. I simply typed "AM4 waterblock" into Google neweggs xc9 rgb was the number one hit so I blindly added it to my cart and hit purchase went through the whole process only once it arrives today did I notice that I bought the lga 2066/ str4 version of this waterblock. There's no return option on Newegg for some reason does anyone know if this block has standard asektek mounting? I don't want to open it in case I need to sell it please any help is greatly appreciated

Asetek Mounting requires a backplate, which this will likely not have since X399/299 boards have standoffs on the socket itself.
