People turn off the fans when it's cooler in the evenings. That's when I turn them on full blast for a time with all windows, doors open. It gets rid of the stale air and the house will be cooler the next day.

I have even got up at 4/5 AM to open up all and turn on fans then. Works very well.

On really scorchio days, 3Wishes iced water bottle idea works great.
