I don't like hearing the Voices in the fan, it sounds like someone is calling me. The bathroom exhaust fan is the worst offender! I'm not a big fan of Fans, but they're far better than being hot!
I have my three fans but it does sound like voices sometimes, I just ignore it, there are so many weird unexplained noises- that the 'house makes' people say. If I listen I get freaked out- I know it's not worth giving my attention to. focus on the light.
