Narrative:

Extract fan began making noise; eventually caused fumes in the cockpit; then during failure emitted smoke in the cockpit; tripped breaker and eventually failed. Smoke dissipated by 10;000. Descent as required in mountainous terrain; late at night; to the nearest airport. Landed underweight on longest runway. All checklists; performance; briefings were completed; flight attendants and passengers briefed; company messaged on acars. Fire and rescue was waiting for us on landing; but not required. Problem began in flight; a acars message was sent to maintenance. No reply during the remaining time in flight. They could have assisted in pulling a breaker; eliminating the dangerous condition. Suggest a faster way to get maintenance in flight.
