The Question .....
The Answer.... It over heated crossing the mountains and blew up, that's why they were available to you...….Why did the fans that I use on my duster come out of a massive motorhome? What keeps that cool going over the mountains?
The belt would cool MUCH better. Here, I'll try to explain it to you with this question: If what covers your Fanny was held up by electricity, or a belt, which would be hotter ?????Okay I take one fan that's driven at 2500 RPMs by electricity and the same exact fan that's driven at 2500 RPMs buy a belt by the motor?
