I was looking at the rest of the article and the GPU portion made me test out my casing, to my surprise my bottom vents are actually are actually sucking air in, If i open my case front door it blows air out now this only happens if my GPU's fan revs up to something like 65%

I tested it with an onion paper/tracing paper.. If it sticks to the vents its sucking air in, if it falls it blowing air out.

I may need a more powerful 140mm fan but im afraid it might add noise.. anyone here in istorya selling good 140mm, pref with clear frame so I can mod the LEDs to white..

before: 3 x 120mm fans @ front as intake, 1 x 120mm fan @ back as exhaust
now: 2 x 120mm fans @ front as intake, 1 x 120 mm fan @ side as intake, 1 x 120 mm fan @ back as exhaust
future: 3 x 120mm fans @ front, intake; 2 x 120mm fans @ side, intake; 1 x 120 mm fan @ back, exhaust; 2 x 120 mm fans @ top, intake (or exhaust, haven't decided yet)...
