Which one of these fans is better in terms of noise and perfermance

The beQuiet fans are rated to be quieter, but I recall a comparison of fans that showed sound spectrum, and the Noctuas had more even distribution, which means less noticeable despite being a couple db louder.
Both will still be well below the noise floor of a typical room even at max speed, so it doesn't matter much.

Show me the graph please

...actually, I just noticed that you're comparing to the industrial PPC version, that fan has the potential to run considerably faster/louder, so it's not apples-to-apples. The PPC fan is louder at similar speeds as the regular ones, so in this case the silent wings would be quieter.

I have the 3000 variant of the nf-a14, they work insanely well with my h110i and I don't ever have to use more than 50% for this 7600k at 5ghz. That being said I don't know how these would work with casefans, of course they would definitely bring a lot of airflow(albeit static pressure fans) at lower rpms than some other fans but around 40% you start to hear it.

I would honestly opt for the nf-a14 ippc 2000 and set it at either 50%-60% or maybe even 70% if you think it's quiet enough, it'll definitely move air for a case.

I'm lookg to know the performance to noise ratio. For example one fan having 60cfm at 30db and the other having 50cmf at 30db. In this regard which fan is better the Be Quiet! or the Noctua?

Same, have 3x industrial PPC, get those and run them around 2000rpm, they're silent enough and even run under water, liteally underwater.

well because slient is a subjective term what DB do they produce at the rpm you run them at?

just search for this stuff urself, noctua 3000 is better imo

Also have a Fractal case and they're quiet, you def need to control them if you're looking for quiet fans then get the standard version or 2000
