Shortly after leveling off at cruise I noticed a smell of electrical smoke. We called the cabin to ask if there was anything in the oven. He replied no and said he smelled the smoke too. It persisted and got worse. Within approximately three minutes we [advised ATC]; made an emergency descent and landed in ZZZ.Dispatch was immediately notified via sat phone of our situation and intentions to divert.The cockpit oxygen masks were removed but were not donned. There was no visible smoke; only the smell. The QRH was accomplished up to the point of troubleshooting the source of the smoke as there was very little time left before landing.An overweight landing was accomplished with a smooth touchdown and minimal braking. No injuries or ailments were reported from the crew or the passengers. An orderly deplaning was accomplished at [the gate].Maintenance personnel identified a tripped circuit breaker for the equipment cooling fan. The fan was removed and had evidence of smoke and soot on the rotor vanes as well as the same smell experienced in the cabin.
A Boeing 757 captain reported an electrical odor smell evident in the cockpit and cabin. The flight completed a successful diversion to a suitable airport.
