zibby is an unknown quantity at this point
I'd say take a look at the fan resitor. Its mounted to the fan housing. Follow the wires from the motor to locate it.If it is a module thing you have to replace the whole fan unit because the module cant be replaced on its own.It is around $500.00 US for parts.
BTW there nothing to laugh about , it is a common problem on BMW with aux fans. It is normal question you have asked !

I think it’s your rad temp sensor the DME controls the fan and if it looses it signal for the sensor it runs the fan, but the fan is permanently feed so it can run after the engine is off so it’ll run all the time

There used to be a Technical Service Bulletin/Recall on the E46 Aux fans. As mentioned in a previous post, this was/is a common issue and involves replacing the module located on the fan housing. Under the TSB, warranty covered replacing the entire fan assembly which included the module.
