Negative air pressure is your friend. If you open the windows upstairs and down and blow air out of the house it’ll suck air from the downstairs to the upstairs cooling the entire house.
Bernoulli’s principle is your friend. Rather than having fans right next to the windows you’ll move more air if you back the fans a meter or so from the window. https://youtu.be/BhWhTbins_A?si=9LGd0_EmfPFBNnDJ

Never heard of Beenoulli’s Principle before, thanks for sharing.
