Default Radiator fans

Hello, my radiator fans wont turn off even after the vehicle is turned off. It drained my battery completely. I already changed the fan relays, temperature sensor, and the blower motor resistor. Not sure what else I need to do. Any suggestions?

Do the fans run with the relay removed?
