ABSTRACT:
An air fan rotation speed control method and a structure thereof aim to provide an automatic control mode and a manual control mode at the same time to control rotation speed regulation of an air fan to achieve instant heat dissipation for an environment and reduce temperature rising of the environment efficiently. The present invention has a rotation speed determination mechanism that adopts the higher rotation speed request at a higher priority to regulate the rotation speed of the air fan in either control mode. Hence the temperature of the environment can be reduced at the higher rotation speed.
