I'm interested to know where your senders are located for the fans/gauge, what therm-o you run.
I have my fan sender in the therm-o housing and the gauge sender in the intake right at the driver head... gauge hangs around 200-210 on hot day at idle with AC blowing and fans running. Fans are set to on=195 off=185. Must be about 10* diff between these two senders or their locations.
