On the engine at the front there is a BLUE 2 pin temp switch that controlls the aux fans. This switch is a very common failure. IF you try to un-plug or jump to by-pass, the fans will still run. You will need to replace the switch or subsitute at least 500ohm resistance to turn the fans off OR remove the aux fan relay.
