Abstract

A projector includes a cooling fan, and a processor, and the processor executes, in a case in which the cooling fan is operating in a first revolution speed mode, a control of switching an operation mode of the cooling fan to a second revolution speed mode whose revolution speed is faster than that of the first revolution speed mode in a case in which an obtained temperature detection value reaches a first threshold, and executes, in a case in which the cooling fan is operating in the second revolution speed mode, a control of switching the operation mode of the cooling fan to a revolution speed mode whose revolution speed is slower than that of the second revolution speed mode in a case in which an obtained temperature detection value decreases below a second threshold which differs from the first threshold.
