Embodiment
[0068] A control method and control device for the fan speed of electronic equipment, aiming at solving the problem of uniform heat dissipation and noise reduction requirements of electronic equipment.
[0069] The invention adopts the strategy of "basic speed + floating speed" to adjust the speed of the fan, selects the basic speed of the fan in the low-speed section, medium-speed section, and high-speed section according to the range of ambient temperature values, and dynamically adjusts the floating speed value of the fan in real time according to the maximum device temperature value change value of each module Combined method to determine the fan speed required by electronic equipment, and realize the organic unity of heat dissipation and noise reduction requirements of electronic equipment; set the ambient temperature change threshold, the device temperature change threshold, and the maximum adjustment amplitude of the duty cycle to reduce the fan speed Adjust the frequenc...
