, then all your CFM problems will be out the window.... probably literary. They can be fan controlled..... if you have a 30 Watt controller per channel.
220.01 CFM @ 4600 RPM,
65.0 dBA, 29.40 watts, 2.45 amps,
Maximum Air Pressure 26.44 mm H2O
Yup, 220CFM at just a mere 65dBA...... Maybe not.
I bought one off ebay just for the hell of it. Great fan... it sprints across any flat surface if not anchored (not a light fan, either), and has enough CFM to power most model aircraft (assuming you could find a large enough battery to power it). The noise is indeed deafening. It will instantly upgrade any room into a server room.
