I do believe there are some aftermarket PWM controllers out there. Many, if not most, new cars use PWM controllers because It is more fuel efficient as well as extending the life of the fan(s), not to mention quieter than having a fan roaring at high speed when it is not needed. Hopefully others will chime in as I am far from an expert. Larry
