Pro tip: Point the fan so that it blows outside and DO NOT put it directly on the window or right next to it. Instead, move it ~50cm away from the window to take advantage of Bernoulli's principle (push the air out more efficiently by pulling the air surrounding the fan).

You can cool down the room even if the door is closed. You are lowering the pressure inside your room so the outside air is forced to rush in. If you place the fan like I explained, and point it at the lower part of your window and you put your hand next to the upper part of the window, you will feel the cold air coming in.
