On the NZXT site if you go to the 820 case and go to spec it says under the clearance section "CPU Cooler 153mm / 183mm without fan". There is then a separate line talking about the GPU "Video 333mm".
Looking in the side of my case it looks like the side case fan and the noctua should slightly overlap however the guy I quoted earlier seems to have made it fit. I'm just wondering how.
Perhaps they don't overlap and it's just my eyes playing tricks on me? The noctua does not cover the first PCIe slot at all on an ATX board. Is the side case fan any higher than that?
