Have any of you guys tried using the OEM fan from a Mazda 6 / MPV / Mitsubishi Outlander?
It is a soft start fan controller that uses pwm on the soft start and then stays running. it has a +12, - and trigger on the controller and then 2 separate connectors to run 2 separate fans. I am thinking about trying that for my car.

Also, I just upgraded from a single spal 14 inch fan to dual spal 12 inch fans and the current inrush at idle turning the fans on is killing the car. On my single 14 I was able to, with some tuning over many hours, get the car to idle well with fan turn on. Not with these dual fans.
