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!
I don’t know the type, so I am judging it from that picture.
It shows a rather small area where the air comes out. I imagine that it creates high speed, but the “channel” would have the exact same size and shape as that small area where the air comes out. So I’d consider it as less effective.
A fan with a large diameter could probably move more air.
