摘要:
An electronic equipment is provided, which comprises a liquid-cooling system and a cooling fan as a cooling system, efficiently cools the liquid-cooling system, and reduces fan noise. The electronic equipment is provided with a liquid-cooling system, in which heat generated in a heat generating portion is transmitted to a heat radiating portion with a liquid as a medium to achieve cooling, and an air-cooling system, in which heat transmitted to the heat radiating portion is forcedly cooled, and comprises a pump that circulates the liquid between the heat generating portion and the heat radiating portion, a fan that forcedly discharges heat of the heat radiating portion to an outside, a temperature sensor that detects temperature of the heat generating portion, and storage information that beforehand prescribes the relationship between temperature of the heat generating portion and voltages of the pump and the fan, the electronic equipment being constructed such that a pump voltage is raised without changing a fan voltage when the detected temperature exceeds a first temperature, and a fan voltage is raised when temperature detected by the temperature sensor exceeds a second temperature higher than the first temperature, thus further increasing a cooling capacity.
