Quick question to anyone that's tried push and push/pull. Did you notice much of a difference between the two? Enough to really matter? I've read the research, but I'm just looking for some hands-on experience comments. I have a 900D, two quad rads, dual 655 pumps, and I'll be cooling a 4960x, rampage iv black, and 3 undecided video cards....prob 780 ti classifieds. I have both rads on push only right now (sp120's) and don't really want to go push/pull. I'm thinking with all that rad space...even though it's coolings some hot hardware....it wouldn't really matter. Am I off on that idea? I'm still building and can make adjustments, I'm taking my time. Any comments appreciated.
