Corsair 250D would like to upgrade fans need help

[Deleted member 362816]

So I am trying to figure out what the best fans would be for this build. I want good air flow but I want it to be quieter then these corsair fans are

Build

250D
Seasonic 850
gtx 770 titan cooler
h100i
i5-4570

The H100i is using the stock fans and I am using the stock fan that came with the case.

Is there a better option for fans here or am I better off keeping what I have?
