Hi there, I've been looking at a few fans recently and have been wondering how you can tell which one is better than the other. Let's say that Fan A has 1,500RPM with 60CFM and Fan B has 1,000RPM with 80CFM and they are both 120mm fans with the same dimensions.

Would I be correct in assuming that Fan A is better because 1,500x60=90,000
which is more than Fan B's 1,000x80=80,000

or, is there something else that decides which fan will provide more cooling?

Is that 10,000 rpm correct? or was that one '0' too many lol,

as it stands the second fan is working much harder to move an extra 20 feet of air per minute and would be insanely loud to boot,
I would go for the first fan.
but no, cubic feet per minute is pretty much the deciding factor of efficiency for fans, after that its just how much noise you can put up with, power drain is largely by-the-by,
