I've found good hi-pressure rated front intakes (3x in your case) with all back PCIe slot covers removed to increase rear vent area around GPU, block all opening in front half of case not covered by intake fans so air they are flowing into case has to move on through case to go out, (not leak around in front of fans and go in circles) and no exhaust fans are needed. (FWIW there's also obviously an exhaust fan at the back of the case) UsandThem Elite Member. Better as Intake, simply because most GPU have more issue with heat management than the CPU, and often yields more noticable results from a GPU boost than a boost on the CPU from extra cooling.

An open-air GPU cooler has exposed heatsink fins on the top and bottom. whether its intake or exhaust depends on where you put it. You should also think how you will have PSU if it has intake fan.

In my case, I do video rendering which puts a small load on the GPU. Your negative pressure graphic is not likely as you would never exhaust out the front. 3. So that means more total intake CFM than exhaust CFM. Edit- Derf- as seen below by the nice gentleman, I said this wrong. If plenty, you could get away with Exhaust with little trade off. Regardless of how my exhaust/intake fans were configured, the upper and lower in-case temps remained relatively unchanged. You also want to match the CFM – that's the air flow rate – of the intake fans to the outtakes.
