DEVICE FOR CONTROLLING DYNAMIC ROTATION SPEED OF FAN, METHOD FOR CONTROLLING DYNAMIC ROTATION SPEED OF FAN, AND PROGRAM FOR CONTROLLING DYNAMIC ROTATION SPEED OF FAN

摘要

PROBLEM TO BE SOLVED: To prevent a fan from excessively rotating at the low loading of a computer without providing any cooling device other than a fan, in the control of the cooling fan installed in the computer.;SOLUTION: A device for controlling the dynamic rotation of the speed of the fan receives an "ambient temperature" which is a temperature of surroundings where the computer is installed, receives a "first device temperature" which is a temperature of a first device provided in the computer, receives a "second device temperature" which is a temperature of a second device provided in the computer, determines the rotation speed of the fan based on comparison between and among the received ambient temperature, the first device temperature, the second device temperature and a fan rotation-speed description table described with a relationship between the respective temperature and the rotation speed of the fan; and instructs the fan to rotate at the determined rotation speed.;COPYRIGHT: (C)2010,JPO&INPIT
