Re: [APD] Heat exchanger - was aluminum in the aquarium
It would have to be a very large fan turning very slowly. A
6" fan would be doing good to produce only 11db while
moving mere 12 cfm.
But then, I don't think there are any standards for the db
measurement. The db level depends on how far away from the
fan the measurement is taken. I can't hear the fans in the
house next door at all ;-)
