No, it's not Gizzo's Fan page, although that does have lots of good info on it. I remember finding a page a while ago that compared the noise output of several fans. It also listed the dBa and CFM for one fan, two together, and three together. I seem to remember it was in spreadsheet form, but I could be wrong. Does anyone know to what page I'm referring? My google searches haven't turned up anything. Thanks.
