Hello,
I'm building a new rig. I'm going too have 5x case fan. 1x 140mm front fan. 1x 140mm side lower right fan. 1x 140mm lower back(about half way up the case) fan. 1x 140mm up back fan. and 1x 120mm top fan. The front and the side will be intake. and the upper back and top fans will be exhaust. What I'm not sure about is if i should have the lower back fan be intake or exhaust and wanted your opinions. I'm also running a XIGMATEK Gaia SD1283 120mm Long Life Bearing CPU Cooler. What's my best option to keep my case cool? I was thinking 3x intake, but I'm going back and forth.

I am not an expert, but in my Silverstone SG-09 case manual they do recommend for the video card area (lower part) cooling 3 x intake fans (1 x 120 mm + 2 x 92 mm) and 1 x exhaust fan (80 mm). By default, for the CPU cooling area (upper part) the case has a large 180 mm intake fan and one small 80 mm exhaust fan. This is a positive pressure approach which also helps keeping the dust out of the case. Perhaps your case manual has some recommendations too.
