So it’s the Ford Contour dual fans which are inexpensive, compact and move a lot of air. The PWM is from a Mitsubishi dual fan application and the latest MS3 firmware provides granular control of the fans. So fans are off until 170 and then I add 40% duty cycle and it ramps up to 100% at 180. I also have it set to cut the fans at 40% TPS so I’m not taxing the electrical system during a run. So far, so good.
