I agree, fans can help greatly. Another tip with fans. Is to go oldschool ice box method and pull the heat out.
During the day keep as many doors and windows closed except the ones with fans PULLING air out of the home. I also turn on my kitchen and bathroom Exhaust fans. (Sometimes the exhaust fans are enough)
During the night flip the fans around and pull in all the cold air of the night. Well…unless it’s hotter outside still lol.
