OMG someone finally gets it. Vertically mounted blower fans. I've been saying for a while this would be the absolute ideal fan-direction orientation.

BTW, I don't know how you'd do this and still mount them like you have, but when we took the PCI brackets off of our 290s, there was a significant temp decrease. It was about a 8C drop on our hottest card. You could hear and feel more air move out the back. I got a picture here:


What kinda settings do you use for 875? The best I could get was 850. And what's this about undervolting? Please link the thread?

Thanks! And kudos to the awesome rig!
