Then how do we feel cool

The fan will increase the total temperature of the room. Due to the mechanical motor with the fan, we illusion of being cool is to do with wind chill.

you know sweating helps to remove heat fromthebody? how does that happen?

yes... I guess evaporation

Sweating helps to remove body heat by evaporation because heat is extracted from body when liquid water changes phase to water vapour. The fan creates an air flow and accelerates the process of heat removal from body to surrounding air as well as sweating. Thus more heat is removed from body and feeling cooler.

But it will increase the K.E of the air molecules. right?

A fan "merely" circulates the air in closed space (example: empty room). The hot air in the room and also the very little air heated up by the action of the fan move upwards due to the centrifugation provided by the fan.

Hot air is lighter (less heavy) than cool air and always tends to move up. this tendency is assisted by the centrifugation provided by the ceiling fan.

Compare: The heat of a candle, one candle in a large room will not significantly increase the heat of the room, unless it is one big candle about the size of a fireplace. Yes, the candle is adding thermal energy to the room, but if the room is large enough and the candle is not very big, it would take many candles to heat the entire room.
