actually , fan never cool ur room ,hope u think ,when i run the fan then i feel some coolness ,
no, u feel cool because ur body water,when air touch ur body then water is evaporated then the water feel us cool.
but u ran a fan in ur room then their is no water , but also fan become hot and hot due to current flow ,and mechanical work, so it increase temperature of ur room.
