Fans don't do anything to actually cool the air. They were primarily used in the past because nothing else was available, not because they were good.

- yosito 5y agoWhen used properly, fans actually do quite a bit to cool an environment. Moving air can carry heat with it.
- cbg0 5y agoLet's say it's 33 outside and 28 Celsius indoors and you're running a fan. How exactly is it going to cool your room?
- yosito 5y agoThere are two common ways to use a fan to reduce heat in a room. One is that you use the fan at night when outdoor air is cooler, to pull in outdoor air and expell warmer indoor air. The other is you use a ceiling fan, spinnng counterclockwise so that it pushes air down in the center of the room that can cool your skin via moisture evaporation, and the cooler air on the floor will be drawn back up along the walls and recycled.
