I was told there would be no math involved ! lol

Obviously, math is not my forte either, because I figured the cubic feet wrong. It should have been 2978.1 Cubic feet per minute, and even that is wrong, because that would only work if it were cubic yards, instead of meters. Anyway, the way that I worked it would come out to 49.635 CFM. That is somewhat low, because of the difference in the measurement of meters and yards, but it still doesn't look like a lot of airflow.

Ciara, That fan has crazy output but man so is 65db have 3 or 4 of those things running and I would need head phones to compute.

Yeah but it fast !

Tornado's are loud too.... but man do they move a lot of air :)

I went to an online converter, and got 3895.207 cubic feet per hour, which works out to 64.92 per minute. Not too shabby, but still lower than the first two fans mentioned. This is probably greater airflow than I have now, but I don't know, because it is the stock fan in a HAF 922 and unless it is on the fan (I doubt) the spec isn't given. Those Noctua fans are still interesting, because of their design and warranty though.

After looking I have two Scythe Gentle Typhoon Fan - 120mm / 1850 RPM in my case one front and one back.
