I previously bought a 460X which I returned due to way higher temps than my current Define S. During Black Friday I found a good deal for the 570X which I thought would be better since it's a bigger case but still my GPU temps are crazy high and I have no idea why. I've populated this case with five fans in total (already included SP120 RGB plus two more) and they're running at about 1100RPM which is loud but tolerable (any higher and they really get too loud). I tried playing Mass Effect Andromeda which is a demanding game making the GPU run at 99% all the time. The GPU runs at up to 77 degrees with the fan RPM up to 73%. In comparison my Define S populated with two AF140 fans, one AF120 and one FD 140mm fan at ~850RPM make the card run at 73 degrees with the fam RPM up to 60%. Is is the tempered glass that heats up the card? If I remove the side panel I get a drop in temperatures of two degrees. Maxing out the case fans only decrease the temps with one degree.
