The fan works well, moves a decent amount of air for it's size. Enough to still be useful from 4 (or a little more) feet away. It is not silent in it's operation. If you are outside, in a place with some background noise, or if you want some white noise it would be just fine. If you are in a quiet office and hoping for silence, it probably isn't for you. It's not terribly loud or anything but you'd definitely hear it.Either way, can't complain when you get something that works exactly as advertised for this price. Thanks.
