The Derale pwm works off of temp sensor supplied with it not off anything in my Holley HP. If I knew about the C6 Corvette fan controller I probably would have gone that way with the HP. That might change in the future. The point of PWM is that the fans come on slowly and are constantly adjusting to conditions. The temp way is they come on at a set temp and off at a lower set temp at full speed, although my other controller that kept popping the breakers would turn on one fan then ramp up the other as needed.
