A method and a device for controlling a fan speed provided and may be applied to a server. According to an example of the method, a target DTS temperature curve corresponding to a current ambient temperature of the server is determined, and then, a DTS temperature corresponding to a current load of a power consumption component in the server is determined according to the target DTS temperature curve, and a speed of a fan associated with the power consumption component is adjusted according to the DTS temperature and a current temperature of the power consumption. The power consumption of the power consumption component and the power consumption of the fan are effectively balances by dynamically controlling the fan speed under different loads and at different ambient temperatures, thereby minimizing the power consumption of the server.
