The Cooler Master backplate nuts are taller than Arctic's.
I have a Cooler master LGA 1700 kit for all cooler master AIO, and it fits the LGA 1700 holes perfectly. The nuts are small for Asus z690-f motherboards and the center of the backplate has some rise. The problem is the design of the backplate and the nuts. The backplate nuts do not line up with the mounting holes on the board. I have informed Arctic about my experience and waiting their offical reply. The main problem is the backplate of LGA 1700. Arctic says 'This can be remedied by removing the PCB cover.
