I have a reference design Asus GTX 680 2GB and am going to water cool it shortly. I've ordered and received a full XSPC setup based on the RX360/Raystorm/Razor/D5 variable pump/dual 5.25" bay res and after feeling the weight of the Razor full GPU block I feel like it could use a backplate to reinforce it. My question is: do I need to worry about compatibility specifically with the waterblock or can I just use a backplate that is compatible with reference design 680s, like the Heatkiller backplate?

Thanks in advance
