Air flow help...Postive? Negative? Neutral?

I've provided a picture of my current fan setup. Any advice and/or suggestions would be great.

The top 2 fans should be exhausting outside of the case imo rather than pulling air in. as heat is easily dissipated that way (hot air rise so this will help ) other than that iut looks okay for me..

As @Tech_Dreamer said, just change the orientation of the top fans. It won't draw in too much dust, and heat rises, so...

heat does rise, but when you add in active cooling like fans you are counteracting that natural convection really easily, if this was a passive build that would be different.  that being said since you have 2 reference style (780's?) I think you have a pretty good setup since they exhaust almost all of their heat out the back.  If they were aftermarket cards I would advise changing 1 or 2 intake for an exhaust that is not your radiator but your case temps should be quite low.  I like it man, I like it

Looks great. As everyone said, switch the top. Also, I don't know how strong the bottom fan will be, but watch out for the bottom font and bottom fan creating a vortex/turbulence which can cause noise. I'm not entirely sure this would happen, don't have enough experience, but it may be something to look out for, especially if the fans are heavily directionalized.

Thank you all for the input. I'll try the top fans as exhaust.

if you've got decent filters the dust shouldn't be too bad

As far as the fans on the rad are concerned; any opinions on running push/pull with a SP120 in Push and an AF120 in Pull or would dual SP120s be ideal?

also just cause you asked in OP, the set up in the picture is Positive pressure.  flipping the top fans to exhaust is now negative pressure

Ok. Thanks again.
