Also note that reviews that actually measure airflow and noise are more reliable than manufacturer specs. iirc, the Noctua specs are fairly close, though.
it depends on the fans itself, if you have cheap fans with a high rotation speed then they will be loud even with only one fan.
if you have good quality fans with PWM connector to control the speed then you can have a good airflow with no noise

Anybody has a case with 2 12cm fans in front ?
Are they noisy?
Thanks for sharing.
In general the higher the CFM/RPM of the fan the louder it will be.
What 2 different people call loud or a acceptable amount of noise will be different.
