Putting in the new electric fan is easy as pie, but where do you plug it into? I beleive the spot you plugged yours into is where the AUX fan used to plug into, well i still go minez. Or do you think im safe just taking out the mechanical fan and relaying on the AUX fan?

(Reason why I dont want to only use my AUX fan is becuase BMW put in a mechanical fan for a reason, extra cooling is clearly intended. If the aux fan could have handled it, they wouldnt have added the mechanical fan)

Sorry for the chicken scratch, but Im in a mess here.
The Aux fan itself is not strong enough to cool the car. If you removed both and replaced it with the electric fan (like I did), it will be cool enough.
