What is better?
A 12v DC fan with a power supply
Fan like this, and power supply like this.
A 120v AC fan plugged directly into wall
Fan like this.
The 120v AC fan has a larger motor while the DC fan has a smaller motor.
What kind of motor does the 120v AC fan use? Is it a shaded pole motor?
NOTE: The fans in the pictures are just examples; I am not talking about those exact fans. I'm talking about any fan.
