Narrative:

We were approximately 10 NM past ZZZ on the arrival descending through FL180 to FL80. At this point we detected a whining noise forward and below our seated position. Duration I estimated to be 15-20 seconds. We then detected a heated plastic smell. We declared an emergency with ATC and requested the ILS to runway xx. A status message of 'fwd eq exh fan' was noted and our fb ran the checklist. He also advised us that the fan circuit breaker was popped. The letdown; approach; and landing were uneventful. ATC handling was exceptional.
