Long story short, I want to set up push-pull on these. I would prefer effective fans that are not noisy. I have got a black and blue theme going and dont want LEDs on the fan, dont want to clip them. I would prefer slim fans, rather than the standard thick ones. Right now I am looking at the Enermax T.B.SILENCE since they sound good on paper. Or maybe those new Corsair fans... Spectre Pro or the GELID Wing Blue. Prolimatech PRO-BV12 has a nice blue version.
