Fan link Hey man I don't know if it'll help but when I had 1 window we used 2 of these with a piece of carboard between them to prevent them flowing directly into each other. If you put the put fan on top blowing out and the fan on the bottom blowing in, use a large piece of cardboard to give about 18-24 inches of wall between them on the inside and out. It works even better if you window opens from the top or the bottom.
