Could Push&Pull done with Mora 2 core and with 2 fan faceplates?(not pro, because you cant mount another one so well)

Generally, a 140 mm fan can be potentially more noisy than a 120 mm fan because it's pushing more air at identical rpm. Below a certain threshhold though, rpm makes no audiable difference in a quality fan, i.e.
I cant know exact number.. its more guess than fact, just like comparing 80mm fan to 92mm or 120mm fan (need to compare same manufacture fan). Bigger fan make more noise in same rpm because its produce a lot more airflow wich will make "hummm" effect.
80mm Nexus(19 dBA@1m: 1110 RPM :15 CFM) vs 120mm Nexus(22 dBA@1m: 1080 RPM: 29 CFM). Found in SPCR site.

You are right 300rpm vs 500rpm is too hard to hear (because they are death silent)
Its like above 600rpm at 120mm fans when they come audible..

Like you said there are many things what affect to noise.. Bearings, rpm, horizontal/vertical, wing type, fan count, yourself (everyone can't hear same noises) etc.. also sound can change comparing free air moving fan vs Radiator fan or insade case vs outside of the case..
