We are sorry to hear that you are having this issue. When properly installed, the fan should operate quietly at all 3 speeds. Most noise issues can be attributed to loose parts (including the outlet box). Please make sure that the outlet box is securely fastened to the house support structure and that all other parts are correctly installed and completely tightened. In general, if an issue comes up with the fan, we suggest calling Hampton Bay customer service at 1-855-HD-HAMPTON (1-855-434-2678). The motor is covered by a lifetime motor warranty and most issues can be resolved over the phone with some minor troubleshooting.
