For the great air cooling below room temperature debate, here's my two cents.
Under typical circumstances, circulating air cannot cool something below room temperature.
However, if there is some sort of liquid condensed on your atomizer (occasionally I'll get condensation or run-off on my 901 if I fill it up with a little too much fluid or use it a lot), then the liquid evaporating (with the assistance of the fan) will actually cool it below room temperature. This is the reason you feel cooler in front of a fan when it's blowing on your face, the sweat on your face is evaporating faster, taking a lot of the heat with it as it evaporates.
