A control device includes: a central processing unit; a cooling device that cools the central processing unit and generates an operation sound during operation; and a temperature sensor that detects a temperature of the central processing unit. The central processing unit: controls the cooling device so as to cool the central processing unit when the temperature detected by the temperature sensor reaches or exceeds a first temperature; executes a first job for performing a process involving a mechanical operation and a second job for performing a process not involving a mechanical operation; and when the temperature detected by the temperature sensor reaches or exceeds a second temperature, modifies a normal process of the second job into a power suppression process such that a load on the central processing unit for the power suppression process is less than a load on the central processing unit for the normal process.
