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.
