11. A work vehicle, comprising:
one or more ground engaging apparatus;
a power source;
a fan rotating in a first direction to generate an air flow in a first direction;
a speed sensor sensing a speed of the fan;
one or more sensors sensing a load of a power source;
a temperature sensor sensing an ambient temperature; and
a controller configured to determine the load of the power source, determine the speed of the fan, determine an estimated speed of the fan based in part on the load of the power source and the ambient temperature, determine a speed difference of the speed of the fan and the estimated speed of the fan, and determine changing the air flow to a second direction based in part on the speed difference and the load of the power source.
