Fan noise level

[nastymat]

I am looking to put a couple of new 80mm fans in my case and was wondering at what db level are they audible? ok.. yes. any level is audible if above 0db but I mean what level is noticeable?

About 20db is supposed to be the point. Remember 2 20db fans side by side will produce 23db.

17.9db with 22+ flow.. looks like they should do the business without me hearing them do it.
