So for now, is there any point in keeping the fans turning on low speed? I could just hook up the resistor with jumpers and see if it makes any difference.


If you temporarily hook up a DC ampmeter to the fan wires you can monitor whether the blades are blocking airflow.
If the amps significantly drop as you drive at higher and higher speeds the blades are blocking airflow.
