anyone have problems with electric fans

I had a 3600 cfm flex-a-lite fan puller fan in small block Challenger. Worked pretty well for me. It had a thermostat that would kick the fan on when needed. Can't remember the model it was but I'm sure that there's one out there that will work for ya. You have to make sure that its wide enough to cover your radiator as it will replace your stock fan shroud if you have one.
