Removing OEM backplate

[Nosrelo]

Hi!

I recently bought a used PC with a Gigabyte Z370P D3 (socket 1151). The mounted cooler looks exactly like a Xilence I250PWM. It does not have any writing on it so it seems to be an OEM version of that cooler.

I bought the PC because my old rig finally died after almost ten years. In my old rig I used a Noctua NH-U12P-SE2. Since I already have it and it's definitely better than that 8$ cooler i want to mount it on the new CPU. And that's where my problem starts. There's a weird backplate mounted to the mainboard. The three screws that can always be found around the socket seem to screw into it. I can not mount the Noctua backplate over this one.  

Will I need something like a standard Intel backplate if I remove this one? the three screws need to screw into something, right? I guess I could always drill through the threads but I don't really want to do that. 

Thanks for any advice!

Can you not use that backplate with the noctua cooler? Do you absolutely need to use noctua's backplate?

It would be a bit of a mod but now that you've said it I guess I could technically get M3 screws or whatever those are and try to mount the front part of the Secufirm system onto the existing backplate. Not sure if that works, though.

If there is a way to mount the cooler as intended by Noctua I'd prefer that...
