James Ang:

The use of fans creates wind which is moving air and the presence of wind increases the rate of evaporation and produces a greater cooling effect.

Fan is used to disperse the mist to reach different parts of the room so that the room will cool down at a faster rate. It is also to prevent the tiny water droplets from combining into large droplets (precipitation like rain cloud) that would fall to the floor and wet the room.
