Information processing apparatus and fan control method
First Claim
1. An information processing apparatus comprising:
- a main body;
a heating device provided in the main body;
a cooling fan provided in the main body, which cools the heating device; and
a fan control unit provided in the main body, which supplies the cooling fan with a control signal having a first value for rotating the cooling fan at a given rotation speed that is higher than a target rotation speed, and which supplies the cooling fan with a control signal having a second value for rotating the cooling fan at the target rotation speed when a rotation speed of the cooling fan reaches a given rotation speed which is lower than the target rotation speed and which allows the cooling fan to rotate at a constant speed.
