Hi all, I've got a great system I recently built and placed in a Lian Li A05N, which so far I love. I've recently purchased the top cover for the A05N with a 140mm fan and am thinking about re-doing all of the other fans in my case as well. Just to give you an idea of my thermals, here's my system. Asus P6T Deluxe v2 Intel i7-930 Noctua NH-U9B SE2 (push pull config) Radeon 5850 1gb Seasonic X650 PSU 6gb Corsair DDR3 1600 RAM Samsung SpinPoint F3 1TB Here's what I'm thinking about doing to my case. Currently the rear-fan is doing intake and the front fan is doing exhaust. This doesn't seem to work for my setup very well. I was thinking of replacing both front and rear fans with Noctua NF-S12B FLX 120mm fans set to be intakes since they have really high air-flow and placing a Noctua NF-P14 FLX 140mm fan on the top to exhaust the hot air. In addition, currently my CPU cooler is setup West-East in a push/pull config pushing air towards the front of the case. So here's my question: 1) Should I setup my cooler North-South with the fans blowing onto the bottom of my video card? 2) Should I go with the Noctua NF-S12B FLX fans for their high airflow, or would my setup benefit more from going with two Noctua NF-P12-1300 120mm fans for their high static pressure? Here's a diagram of my proposed setup... Finally, this is more of a education thing for me since I don't know a great deal. What is more important in a fan setup? Airflow? Static Pressure? A mix? How should the two interact? What balance should I be striking? Any help here would be greatly appreciated!
