Abstract
(EN)
A fan control method and apparatus, and an electronic device. The fan control method is applied to a system comprising a fan and multiple heat source modules and comprises: acquiring temperatures corresponding to multiple heat source modules (201); determining a control temperature according to the temperatures corresponding to multiple heat source modules (202); and determining a control signal of the fan according to the control temperature, so as to control the fan to rotate at a certain speed (203). By collecting the temperatures of multiple heat sources, the rotation speed of the fan can be accurately controlled, thereby satisfying heat dissipation requirements of multiple heat source modules.

L'invention concerne un procédé et un appareil de commande de ventilateur, ainsi qu'un dispositif électronique. Le procédé de commande de ventilateur est appliqué à un système comprenant un ventilateur et de multiples modules sources de chaleur, et comprend : l'acquisition de températures correspondant à de multiples modules sources de chaleur (201) ; la détermination d'une température de commande en fonction des températures correspondant aux multiples modules sources de chaleur (202) ; et la détermination d'un signal de commande du ventilateur en fonction de la température de commande, de façon à commander la rotation du ventilateur à une certaine vitesse (203). Par collecte des températures de multiples sources de chaleur, la vitesse de rotation du ventilateur peut être commandée avec précision, ce qui permet de satisfaire aux exigences de dissipation de chaleur de multiples modules sources de chaleur.
