Be quiet dark rock 3 install question

[Wayfall]

Hi

I have an Asus x99 A-II and it has a built in backplate. There are already standoffs around the CPU for coolers. How do I install the Dark Rock 3 onto this motherboard as from the videos you have to screw it in from the back but I can't do that with this board.

Use the included instructions, or find a video for that cooler on LGA2011 installation.
