Review: Great fan and moves a lot of air. - My kitchen was always cold. This cured the problem. It does make noise. Like the pink noise between FM channels on an old analog tuner with a low hum. It is not loud, but plainly audible. My other biscuit fan is virtually silent but this moves twice as much air. I added a line switch for when I need total quiet. It also does not have a pivot on the mount that my old biscuit fan did. It will only point directly straight. Review: Noisy - It does seem to move air. However, it can be heard two rooms away. Defeats the purpose if you want to sleep. It's in the room next to the bedroom and even with the door closed it will be pretty prevelant. Not a pleasant white noise either. ## Features - 110 CFM, 18 Watts.
