Replacing A4000 PSU fan - Enough Airflow?

I would like to replace the original fan of an A4000 PSU with a more silent one : The NoiseBlocker M8-S1.

I'm however a bit worried with the airflow of the NoiseBlocker M8-S1 fan, which is only 30 m3/h.
The original fan of the A4000 PSU is a Max Flow MF8025, which has an airflow of 45.65 CFM = 77.56 m3/h....

Should I be worried, or is 30 m3/h enough?

I am also interested in this

The A4000 is a noisy beast and would really suit a quieter fan.

My A4000s are not noisy. In fact, I'm currently hearing the hard drive (a modern one) over the fan sound of two A4000s.

I swapped the fan out in my A4000 power supply and it made a huge difference.

It's almost silent now. The only thing making a noise is a HD. If I disconnect the HD and use a CF <> IDE adapter it's completely silent.

I think this is what I bought:
