All gauges are normal, but radiator fan idles up to high for no reason. What

Is the heater controls set to defrost the windshield? In this position it also runs the AC compressor so it turns on the radiator fans. Check for proper coolant levels. If still stumped you my need to have a shop run a live data scan on the computer system, they would be looking for any misreads on sensors.
Have the cooling system checked. It might be as simple as a faulty Engine coolant temperature sensor or switch.
