COOLING SYSTEM, COMPUTER DEVICE, COOLING FAN CONTROL DEVICE, COOLING FAN CONTROL METHOD, AND COOLING FAN CONTROL PROGRAM

摘要

PPROBLEM TO BE SOLVED: To prevent the generation of a noise by making it unnecessary to perform any excessive cooling, and minimizing the speed of rotation of a cooling fan even when applied to a casing loaded with a plurality of cooling fans. PSOLUTION: A cooling system includes: a plurality of in-apparatus temperature sensors for acquiring the temperature of a plurality of devices loaded in an apparatus; a plurality of cooling fans installed in the apparatus; a plurality of cooling ducts for exhausting the outputs of the plurality of cooling fans to a plurality of device sides, and for varying duct angles determining the exhausting directions; and a cooling fan duct angle control part for variably controlling the duct angles determining the exhausting directions of the plurality of cooling ducts so that the outputs of the plurality of cooling fans are centralized at the device side positioned at a high temperature part in the apparatus based on a plurality of in-apparatus temperature sensor values obtained by a plurality of in-apparatus temperature sensors and a preset temperature upper limit value of each of the plurality of devices.
