Information processing device with sensor detecting movement of device housing

An information processing device comprising:

• a sensor configured to detect a change in an attitude of a housing;
• a rotation member cornprising a shaft;
• a support for the rotation member;
• wherein the rotation member is a cooling fan configured to cool the housing;
• and
• a control section configured to control the rotation of the rotation member, wherein
• the control section is configured to perform control such that, when the sensor detects that the attitude of the housing is changing, the control section stops the rotation of the rotation member or decreases the rate of rotation of the rotation member to be lower than that in an ordinary operation to suppress contact or friction between the rotation member and the support that may occur due to temporary misalignment of the rotation member and the support, and thereafter, when the sensor no longer detects that the attitude of the housing is changing, and an original alignment of the rotation member and the support is present, the control section returns the rate of the rotation of the rotation member to that in the ordinary operation.
