blow air into room from outside and blow air out of room to the outside at other end of the room

Need more information. Is the room open to other rooms? Is there AC running? Is there a window open? Is it cooler or hotter outside than inside?

Open two windows on opposite walls so you can get a cross breeze.

That is rule number one.

Hmm..I
f you have two windows open and one fan, is it better to put the fan by one window with the fan blowing out or in???

Does it make a difference?

If one fan, you would want it to blow out. This will create a vacuum and draw the cooler air into the building.

Fan pointed out the door of the room.
The air will pull cool air from outside, door closed is useless.
