Abstract: An information processing apparatus includes a fan that cools a first processor, a dust-proof bezel that prevents dust from entering a casing, a memory, and a second processor coupled to the memory. The second processor is configured to measure a temperature of the first processor and an air volume of an air flow which passes through the dust-proof bezel, compare a registered air volume to the measured air volume when the temperature matches a registered temperature included in comparison information stored in the memory. The registered air volume being included in the comparison information in association with the matched temperature and the comparison information including a registered temperature of the first processor and a registered air volume of an air flow generated by the fan in association with each other. The second processor determines an abnormality in the dust-proof bezel based on a comparison result.
