Doesn't Andrews fan work fine with a constant 12v? If so, ideally, we'd find a fan that needs the PWM. If the fan works fine with a constant 12v, it should still work fine with the PWM, so we haven't really proven that the PWM keeps the controller from dieing.

I don't want to make you rush to finish the hotrod, but sometimes a kick in the rear is handy


I'm about to go ahead and get a 175A tuff stuff alt. Then I could actually install this fan and test it. It also started snowing again tonight, soo...I really need a garage

I did get the sensor tested and mapped out today, so about all I need to do now is add that to the code, then make the prototype more rugged, and send it to someone.
