Hello - I am curious if anyone is using a PWM fan controller like this on either a Gen 3 or 4 Coyote:

This unit provides a low/high on/off as well as variable speed utilization so the fan isn't either off or running 100%. I used this unit previously on a dual Spal setup and it worked great. There was a fairly lengthy thread about 4 years ago discussing a similar option but I haven't found anything more recent:

I also am not sure what fan is being provided by FFR and if it can even accept PWM control for variable speed operation i.e. must be a brushed fan motor.
