Pacco,
If you can get to your fan and the wiring, try to follow it and see where it connects. I had twin pushers in my Classic roadster and an adjustable thermostat switch which I set on the highest setting, but still had to turn the fans off on normal days or mine would never get above 180. I was tracing the wiring one day and found it was all messed up, so I just cut it out and got some new wire and ran my own from the fans to the controller and also to my dash on/off switch. I never had a problem after that with them coming on at low temperatures.
