Server and method for protecting against fan failure therein

A server, comprising:

• a plurality of fans;
• a storage unit;
• a plurality of rotation speed sensors, configured for detecting rotation speeds of the plurality of fans;
• a plurality of timing units, configured for timing continuous working time periods of the plurality of fans;
• a fan failure detecting module, configured for comparing the detected rotation speed and the timed continuous working time period of each fan with a corresponding predefined rotation speed and a corresponding predefined continuous working time period, generating results of the comparisons, and determining whether any of the results for any one or more of the fans fall into one or more predefined failure conditions stored in the storage unit;
• a countdown unit;
• a countdown control module, configured for obtaining a countdown time period stored in the storage unit and controlling the countdown unit to start a countdown based on the countdown time period when any of the results for any one or more of the fans fall into one or more predefined failure conditions;
• a shutdown unit;
• and
• a shutdown control module, configured for controlling the shutdown unit to shut down the server when the countdown reaches zero.
