Abstract: A liquid cooling system cools a central processing unit (CPU). A second temperature sensor detects the state of the CPU. A first temperature sensor detects the state of the liquid cooling system. A liquid cooling system operation control unit determines whether the liquid cooling system is operated. When the liquid cooling system operation control unit determines the liquid cooling system is operated, a CPU power control unit controls power supply to the CPU based on the state detected by the second temperature sensor. When the liquid cooling system operation control unit determines the liquid cooling system is stopped, a liquid cooling system protection controller controls power supply to the CPU based on the state detected by the first temperature sensor.
