In addition, we could ask how the fan blades could stay attached to the fan long enough. Induced fusion is enough to evaporate the whole building in either case, but if we start with a few blades moving at up to 90% the speed of light we get several plasma clouds moving in different directions!billy_joule said:What if is a great site answering these sorts of questions.

An overhead fan works by rotating its blades, which creates air movement that helps to circulate and cool the air in a room. The rotation of the blades also creates a wind chill effect, making the room feel cooler.
An overhead fan is typically powered by electricity. It is connected to a ceiling fan box, which is wired to a switch on the wall. When the switch is turned on, the electricity flows to the fan motor, causing the blades to rotate.
An overhead fan usually has a pull chain or remote control that allows you to adjust the speed of the blades. The fan motor has multiple speed settings, which determine how quickly the blades rotate and the amount of air movement in the room.
The direction switch on an overhead fan allows you to change the direction of the blades' rotation. In the summer, the blades should rotate counterclockwise, creating a downward airflow that cools the room. In the winter, the blades should rotate clockwise, pushing warm air down from the ceiling.
An overhead fan can be used as a supplement to an air conditioner, but it cannot replace it. While a fan can help to circulate and cool the air in a room, it does not actually lower the temperature. An air conditioner, on the other hand, actively cools the air by removing heat and humidity.
