Abstract
A method for protecting against fan failure in a server uses a storage unit and a plurality of fans in the server. The method includes the following steps. A rotation speed of each of the plurality of fans is detected. A continuous working time period of each fan is timed. The rotation speed reading and the continuous working time period reading of each fan is compared with predefined rotation speed values and predefined continuous working time periods stored in the storage unit. The results of comparisons are made. A countdown is started when any of the results of comparison falls into one of predefined failure conditions for the fans. Unless a renew or other countdown-amending signal is received, the server is counted down to zero and then shut down. A server equipped to be able to carry out the protecting method is also provided.
