Best way to cool at room at night with a window fan?

Question

Should the fan blow inward (blowing the cool air from the outside in) or blow outward (blowing the hot air in the room outside). We do not have any other windows open in the house.

Answer 1

blowing in. if you had another window open, you should face the fan out to create a cross breeze... but since just one window, blow the air in.

Answer 2

top window open and use a fan.

Answer 3

you really need cross ventilation  do you have 2 windows in the bedroom? if you do put the fan blowing out and open the other window it will cause a cross breeze venting the hot air and letting the cool night air in the other window also really helps if you close the bedroom door
