I just got this fan a few days ago to replace a noisy relatively power hungry inline fan i already had. My first impressions are pretty good. I haven't installed the fan how I want yet, but I have messed around with it. First off, the description says it's 68 watts, I hooked it up to my kil-a-watt, and at maximum speed, it only draws 59-60 watts. So that is deffinately a bonus. While down at speed 2, it draws about 11 watts and still moves a decent amount of air. I do not have an anemometer or anything to verify flow rates. As far as noise, I haven't checked it with a decibel meter, but it's not the loudest fan in the world. Speed 2 you almost can't hear it, at 3 you start being able to because the Humm it creates is sort of a higher pitched Humm, not a deep lower tone. At speed 10, it gets kind of loud but not the loudest fan I've had. This review could possibly be premature, but overall I'm satisfied so far.
