Some embodiments relate to a generator that includes an alternator and an engine. The engine includes an output shaft that is coupled to a rotor of the alternator. The generator further includes a first fan that initially directs air in a first direction which is parallel to a longitudinal axis of the output shaft. A second fan that directs air in a second direction that is orthogonal to the longitudinal axis of the output shaft. The generator further includes an enclosure such that the alternator, the engine, the first fan and the second fan are within the enclosure. In some embodiments, the generator may further include a third fan that directs air in the direction that is orthogonal to the longitudinal axis of the output shaft and a fourth fan that directs air in a direction that is parallel to the longitudinal axis of the output shaft.
