After 4 deferent  fans in the bedroom I finally found what I was seeking!!! I love total silence and the buzz or hum from a normal fan I could not deal with. Tried wall switches that were suppose to help but don't. Finally after much research I decided on a DC motor and the Minka Air fan. FINALLY a silent fan, no buzz no hum nothing!!! I love this fan!!!  Very easy to install and everything works like a champ with the remote. And the light is awesome from dim to very bright. Can't say enough good about it. I will be replacing the one in living room also even though it is only a few months old. 
If you like quiet use a DC motor and a Minka fan. Well worth the extra $$$
