I would recommend Noctua, be quiet! or NB eloop fans if they are in your budget, and you don't care too much about colour scheming, but the Corsair fans aren't too bad. I would go with dual 140mm front and top because they would provide a better noise to airflow ratio. Front as intakes and top as exhaust and then run the Exhaust fans at a slower Rpm to make a slightly more positive air pressure.
