Remove unused PCI slot covers for more exhaust.
Leave I/O shield off on I/O for more exhaust
SA SB-E E exhausting out back.. or maybe top with fans middle and back of cooler
With SA SB-E E having TY-143 fans 130cfm/2500rpm you need similar exhaust capabilty behind it. I cut out my back vent and built duct out to accomplish this. biggrin.gif

Bottom fan for intake? Won't that push hot air back into the video card? smile.gif

The hardest part of case cooling is supplying cool air to components. Your GPU has 2x intake fans on the face/bottom. The heat exhaust air blows out all the way around the cooler; toward mobo, side cover, front of case and back.

Cool air in front and in bottom all feeds the GPU fans. The heated air coming off of GPU is overpowered and pushed away from GPU fans.

Cool air pushing in the front and bottom exhaust pulling out.. My guess it will be pull cool air out, not hot air.... or mix heated air into cool air from front intakes. wink.gif

Wait, wait. The ACX cooler takes its intake from the bottom of the case? If yes, I feel really stupid. I thought that was the exhaust.

The fans on EVGA GeForce GTX 780 w/ ACX Cooler push air into the GPU housing.

What cooler and fans look like off of circuit board.

FYI: Removing the stock shroud & fans and replacing with 2x 120 fans almost always operates quieter with lower temps is. wink.gif

any/all none reference cooler fans blow air TOWARDS / through the heatsink . so yes it intake from the bottom and blows upwards.

you can tell what direction the fan blows by looking at the way the fan blades curve

Thanks, guys, this was amasingly helpful. I didn't take a good look at the blades---I only read it online somewhere and assumed it was true :-/ I am certain that I can cool it effectively now.

Thanks again biggrin.gif
