Cool it sounds perfect. I'll look into it as well since I plan on going dual fan as well.This, from what I hear, is a better controller. It's a variable speed heavy duty fan controller that starts the fan/fans at 60% then to 100%. Also keeps the fans going for 30 seconds after you turn the engine off. I am in the process of installing this controller on my Notch right now for my dual fans.
