Last month, I picked up this fan https://www.walmart.com/ip/Hyper-Tough-Sealed-Motor-Drum-Fan-with-Wall-Mount-20-Inches/334273417 from Walmart. Its a sealed motor shop fan, so it's much safer for in a dusty coop, than a standard motor fan. This thing moves a TON of air! Possibly a negative for some as it blows hard even on low. Not sure about the energy efficiency but I doubt it is very good. I only use it when temps are real high and the birds love it. To have the peace of mind of a sealed motor for that price is great. I have seen a lot of people on here looking to use fans and talking about box fans etc. Don't do it...not when you can get a much safer alternative. I have mine mounted with the hanger hook and it works well also.
