Need some new case fans for my Corsair C70, needed some advice.

So I need 2 140mm fans and 3 120mm fans for my PC, for me airflow is a big thing I want as my GPU kicks up a lot of heat, sound would also be a factor too, the lower the better.

noctua do nice case fans, or the corsair silent series too
