Playing devil's advocate here...
Why? When is it needed?
Recall, the aux fan on the 560 is designed to only come on when:
1. The engine temp is above 105c
2. The A/C drier pressure is above 20 Bar (approx 300psi)
Be sure you are not masking a problem by treating a symptom, ie using the aux fan when other than designed.
