    Don't quote me but I would be inclined to suspect that the switch that fits into the radiator is at fault and stuck in the ON position. These are normally found on the side, 2 wires, plastic body.

    Modern vauxhalls tend only have one temp sensor for the ecu that then goes onto the fan relays. If this goes faulty it will run the fans as a fail safe

    Try doing the pedal test to see if any fault codes are stored
