140mm fans won't have very good static pressure. the larger the fan, the worse static pressure, unless they're very deep - and nobody makes 50mm deep 140mm fans.
The best out there by far are Noctuas... but those definitely aren't black.
Your best bet is a Corsair fan, but they do have way lower static pressure than the notcutas. That being said, the reason you want static pressure is for a heatsink or radiator. If this is just a case fan, you don't really need it at all.
