So, the locical choice then is SR2 420 keeping the fans, but I really am thinking of swap them for be quiet! Silent Wings 3 140 High Speed PWM. My choice for A12x25 (this specific SKU) is because the told marables about noise profiles even with turbulence to be push or pull on rads. It is like more a sound choice than a performance choice. What do you think about?
I heard/read good things about the Silent Wings 3, but (sadly) have no experience with it. I've been using Noctua fans for years, as well as their CPU air coolers before I started with water…
I also have A14 (actcually A15). I like it, but, if I will pick an 140mm fan, I will stick with SW3 (sounds matters and everybody says it is superior than Noctuas 140 mm in this matter considering static pressure by sound bearing etc).
Now you have me wondering if I should replace the A14s with SW3s.
But I think I will wait until Noctua releases the NF-A12x25 design in 140 mm size, hopefully this year (I think they only said that it wouldn't be 2018, or so I read). The A14s are totally fine for me at ~800 rpm.
The bottom 3 rows in this picture seem the most relevant
Thanks. Your conclusion?
: As expected the 140 mm fans have better airflow before and
after the radiator, at significantly lower speeds, which makes them seem superior. Unfortunately there are no sound measurements, only the mention that the NF-A12x25 are indeed very quiet. Does that make up for the higher speed? I don't know. Haven't found any other conclusive reviews vs 140mm fans either. I sort of want to try.
Do you recommend I purchase a flow meter rather than a flow sensor?
Honestly, I don't know the difference and may have used both terms interchangeably. I only know (have) this one
and like it. It does its job and I can't hear it.
