After installation we all noticed how loud the hum is from the motor which was disappointing after it was advertised as a WhisperWind motor. If you increase the fan speed the hum increases accordingly. I contacted Hunter and they issued a ticket and provided a replacement, which I just received and had installed. The replacement fan hums just as loud as the original, if not louder. I purchased a Hunter Fan for their reputation of building quiet and quality products however this model does not live up to that. I had purchased another Hunter fan (different model) for a different room and that one works silently and perfectly fine so I believe this particular model has this loud humming issue. It's too bad because I do like the look of the fan and it fits well with my decor but they could have done something to improve the performance. This is NOT a quiet fan!
