The interior of your house is hot, the exterior cool. What would the most efficient orientation be for a box fan? Pushing hot air out of a window or pulling cool air in through it? (Solved)* - eviltoast

Secondarily, should the fan be outside or inside the window?

Asking for a friend. (Me, help. I can’t remember physics, it’s too goddamn hot)

Edit: I’ve opened all the windows and set up a fan a short distance from the window pointing out and it’s reduced the temperature to near-tolerable levels. Unfortunately, venting through the attic was a no-go but moving things aside might make it an option next time. Thank you all, I appreciate the help!

    We put ours in the ceiling between the attic and the top floor. Pull the air out of the house, open the windows at night. I’ve heard it called a “whole house fan”. I would occasionally turn it on with the windows closed while the air conditioning was running to, uh, make it go faster, but I’m not sure you’re supposed to do that. Cooled the place down in seconds tho.
