So what would be the optimal fan setup then (prior to cutting holes)? The room is at the end of a west facing hall (sun directly at it in the afternoon) Where you walk into the door, and as you walk straight in, there is a large window opposite the door (the one that gets the sun) and then a smaller window on the left hand side, chest high. The air vent is right next to the door. Kinnda hard to explain, but what are some tips on setting up fans for optimal air flow? Cause even with the computers off all night, the room is still 82F by mid-afternoon today, and that just doens't seem right. That air must just be trapped in there.
