A fan does NOT cool the air! What it does do is circulate it, this gives a breeze (or even wind) effect that then hits your body and causes you to cool down in the same way as a real breeze/wind would.

A regular fan doesn't cool the air. It just circulates it around which causes an impression of "coolness", because moving air feels cooler than stagnant air. Now, if you can find a "swamp cooler" those actually DO cool the air by blowing it over top of some cold water.

In stagnant air, as your body releases heat, the air around you heats up and feels warmer, because it is warmer. If the air is circulating, then the warming air is continually circulated away and you will feel cooler and be able to lose heat more efficiently. (When warm air is around you, the heat from your body will not be lost to the air as readily as when cooler air is around you.) This principle is also the reason why a fan can be used to cool a CPU in your computer. It is not just a perceptual coolness that is being felt, it is a real effect. As this would suggest, if the temperature of the air is much above your body temperature, then a fan will not make you feel cooler, but will actually make you feel warmer. This is an affect which is quite noticeable in some regions during the summer.

thanks Seanmcox!

As it oscillates the air, it creates a wind chill, hence lowering the temperature of the air.

No, it only cools whatever is infront of it,an air conditioner cools the room.

If it circulates the air it can cool a room , my fans have a pivots that goes back and forth , can't think of the name if it + 5
