Abstract:
1. A fan control apparatus for cooling an inside of an equipment body by a cooling fan arranged in said equipment body, the apparatus comprising: temperature detecting means for detecting a temperature in said equipment body; temperature control means for controlling said cooling fan according to a temperature value detected by said temperature detecting means; communication means for communicating over a network with a server at predetermined intervals, the communicating being carried out for a predefined duration during each predetermined interval; and time control means for controlling said cooling fan in association with the communicating performed by said communication means, the controlling of said cooling fan being performed by said temperature control means and said time control means such that said time control means stops operation of said cooling fan during the predefined duration that the communication means communicates with the server and causes said cooling fan to operate in a low state after the predefined duration has elapsed, and said temperature control means causes said cooling fan to operate in a high state whenever the detected temperature value is greater than or equal to a predefined value regardless of whether the predefined duration has elapsed.
