Claim 12:
13. An engine driven power supply, comprising:
a housing having a first area that includes an engine and a second area that includes a temperature sensitive component, the housing comprising a duct configured to channel air heated by the engine from the first area to the second area to heat the temperature sensitive component when the fan is forcing air in the second direction;
a fan configured to force air in multiple directions through the housing;
a temperature sensor to measure a temperature;
a controller configured to:
control the fan to force air in a first direction into the first area when the temperature exceeds a first threshold temperature value; and
control the fan to force air in a second direction into the second area when the temperature is below the first threshold temperature value; and

a mechanical device associated with the fan and configured to adjust an angle of the fan with respect to the housing to change an angle of at least one of the first direction or the second direction of the forced air by changing a position of the mechanical device, the controller configured to control the mechanical device to change the at least one of the first direction or the second direction of the forced air based on the temperature sensor.
