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.
