It's not loud and I usually don't notice it but with Noctua Redux fans I only heard the aerodynamic noise. So a tiny bit of buyer's remorse here.
That sounds broken

So, be quiet! Silent Wings 3 it is then. They are really good at low RPM - misunderstood that part about "PWM high speed"?

P.S. BTW, at the moment I'm using eLoops as radiator fans + one Noctua A14 chromax, and I must admit, overall, six 120mm NoiseBlockers are way quieter than one 140mm noctua. That might be placement issue, but this made me think that I should ask for options first before blindly buying noctua once again :/

The "PWM high speed" is PWM control with maximum speed of 1600rpm instead of maximum speed of only 1000rpm. While probably 99% of the time 1000rpm is as fast as you will run them, there might be a few occasions when the extra speed will be nice to have .. like super hot days when case filters are dirty.

doyll Indeed, even if Silent Wings 3 have same DBa sound pressure level it's a much more pleasant sound so we don't notice it as much.

So basically, the best options for airflow under 800/1000/1200rpm, right?

Best in my book are be quiet! Silent Wings 3 140mm PWM high speed with same in 120mm 2nd best, but only because 140mm fans tend to flow more air at same noise level by a 2:3 ratio. It takes 3x 120mm fans to equal the same airflow as 2x 140mm fans making less noise.

Thermalbench is down at the moment, or I would post up data. The be quiet! Silent Wings 3 are pretty much the undisputed leader in airflow to noise in 120 and 140mm, and have a really smooth sound signature.

Pure perfomance or perfomance/price, but price isn't the most concern here atm.
