I'm sure ill get unanimous no's on this but has anybody ever tried using automotive type electric fans for canopy cooling. I know that full speed would be way too loud, but maybe on a lower speed would be tolerable.
sure why not. But Im pretty sure it would be cheaper to just go to walmart and pick up a clip on fan or if your canopy is big enough one of those dual window fans.
I use a window fan in my canopy and one on my sump for cooling.
