The trigger from the 1050 provides constant current while the receiver is on. Unfortunately, the documentation on the website is incorrect. The DC trigger port provides 6 Volts DC at only 5 Milliamps. Not very much current. In fact, it wasn't enough to trigger my Parasound HCA-1500 amp so I have to leave thae amp on all the time.

If you can find a fan that'll run off that little current, you should be fine.
