Mine has three fans that all make different noises.

1. The fans on the cooling units - these in combination with the coolers are the loudest

2. The fans on the humidifier chambers are the second loudest

3. Mine has a small black fan in the back that comes on to circulate the air which is almost silent.

When all three are running, the thing is pretty loud. I have gotten used to it, but in the beginning, it was a little much. My wife was not pleased. lol
