I thought I would get used to this, but it is really annoying. Do they all sound like this, or am I just lucky? How can a fan so small make such a wonderful noise? I have it in the master bathroom, because that is the room with the most constant temperature in the house. I hear it while I'm sleeping and keep having these nightmares of being at the dentist office. It might be better if the heater going off and on didn't change the tone. Gives it that sense of realisim. Will the chicks end up fearing the dentist as much as I do? Oh well, only 18 more nights to go.
