Amount of airflow in a case is determined by 2 primary factors, size of fan blades, and speed at which they are turning (orientation also plays a big role but that's not important in this comparison).
Now to increase air flow, you either have to use bigger fans, like the HAF's 200mm ones, or spin the 120mm ones in the CM690 faster. Unfortunetly, higher fan speed results in higher fan noise.
Therefor, using large fans will in general, provide equal air flow for less noise.
Now, there is a limit to this, as at some point, the noise from air moving becomes louder than the fan motor noise.
