Regardless of being 20 or 30 series or the teorical thermal benefits claimed by having one, certain backplate thickness interferes with routing the riser over the GPU side on a DanA4 (v4.0 in my case). For instance, I have a Gigabyte 2070GOC with backplate and it was not possible for me to route the riser cable behind that GPU. It didn't lay back enough to insert onto the pciE slot and get screwed properly. Luckily I could route it behind the MoBo side, but that's something you can't do with all motherboards, especially if you plan to use the rear M2 slot.
