Better solution for case airflow Noctua nf-s12b (@1200) vs Corsair ML 120 (@1500 or @1200)

[xeon_fan]

Hi ! I search for quiet solution for one of my PC. I need 3x120mm fans. Could anyone provide information which one would move more air in the case at given speeds?

I have Corsair ML 140 pro and they are quite quiet @ 1200 and I wonder if version 120mm would beat cheap version of noctua's redux nf-s12b which is 40% cheaper?
Never had noctua and I don't know how it behave @1200 (max) yet according to the spec it's very good (CFM and Noise)

Also noctua comes with 6y warranty.

Thanks for the help !

Ok noctua nf-s12b is not good to pull (intake) with dust filter(some old cooler master case fans were better, with noctua gpu temps went + 4 and there was zero positive pressure in the case )
Need to check nf-f12 noctua vs corsair ml120

Check the Noctua NF-S12A, they push a lot of air and are quiet.

Hey, it seems I need more static pressure to get air past dust filter. NF-s12a is even worse than NF-s12b in that matter. Also it's quite expensive.

What do you mean get past air filer?

The fans are on the inside of the air filter.

The back fan just blows out.

Shouldn't be any problem.

You don't need higher static pressure to pull air though a dust filter.

Was expecting the same yet it did not work. Air should flow like this:

<- noctua <- dust filter<- case <-

And nf-s12b failed miserably compared to two stock fans from cooler master haf xb + aab silent(noctua was as 3x 120 configuration).

I expect even worse results from nf-s12a add they have even worse static pressure which seems to be important.

Air filter is on the outside of the case, then the fans.

Air filter before the fans.

Dust filter is inside of the case as the noctuas were. At 1200rpm they were worse than 1500rpm 6 yo fans...

Went with 3x corsair ml 120 and it's great !
- super quiet at 1200 rpm
- allows me to have 45-48 gpu and 65 gpu temps in full load.
Thx for help
