1. An image capturing apparatus including an image capturing unit, comprising one or more processors which function as:
a determination unit that determines a subject and a shooting environment based on data obtained by the image capturing unit, the data indicating how sensitive the shooting environment is to an operating noise of a fan;
an air cooling unit that rotates the fan for cooling the image capturing apparatus;
a thermometer that measures temperature of the image capturing apparatus; and
a control unit that calculates a fan rotation number per unit time of the fan rotated by the air cooling unit based on the temperature measured by the thermometer,
wherein the control unit further sets a fan rotation number upper limit value of the fan rotated by the air cooling unit according to the result of determination by the determination unit, and if the calculated fan rotation number per unit time exceeds the fan rotation number upper limit value, the control unit limits the fan rotation number per unit time to the fan rotation number upper limit value to limit the operating noise of the fan to minimize interference with the shooting environment even when the temperature indicates the fan rotation number greater than the upper limit value of the shooting environment.
