Abstract:
An information processing device that permits internal mounting of a relevant device, comprising:a cooling fan having variable rotation speeds, temperature obtaining means that obtains a temperature within the information processing device, attaching-detaching state obtaining means that obtains an attaching-detaching state of the relevant device, control means that controls the rotation speed of the cooling fan; and reference data storage means that stores reference data, which is determined depending upon attaching-detaching state of the relevant device, showing the relationship between a value relative to the rotation speed of the cooling fan and the temperature, wherein said control means determines the reference data to be referred to, on the basis of the attaching-detaching state of the relevant device obtained by the attaching-detaching state obtaining means, calculates the value relative to the rotation speed of the cooling fan from the temperature obtained by the temperature obtaining means and said reference data, and controls the rotation speed of the cooling fan on the basis of the obtained value.
