In a cooling structure for use in a disk array apparatus, having boxes 27 , each containing disk drives 26 therein by a lager number thereof, in each of the unit housings 114 are provided a air-blow fan 33 , and also a liquid cooling system having a pump 107 for transmitting a liquid coolant, a radiator for discharging heats absorbed within the liquid coolant into an outside air, and pipes 101 for connecting those, etc., wherein a rotation speed of the pump is detected by a temperature sensor 120 attached on the pipe in the vicinity of an inlet of the radiator, thereby changing it depending on the temperature detected. With this, it is possible to achieve an improvement on cooling performances of the disk drives, which are contained within the housing of the disk array apparatus, and also to reduce an increase of temperature of the disk drives and unevenness in temperature among the disk drives, thereby enabling an improvement on the reliability and long lifetime of the disk drives and the cooling system thereof.
