Abstract: Disclosed is an optimization method for heat dissipation control. An information reading frequency and an optimized heat dissipation control cycle of each GPU accelerator card are obtained. A maximum number of information readings of each GPU accelerator card within one optimized heat dissipation control cycle is obtained according to the information reading frequency and the optimized heat dissipation control cycle. Other information, in addition to the temperature information, to be read during a current heat dissipation control cycle is determined, so that the sum of the temperature information and other information to be read does not exceed the maximum number of information readings. An information reading instruction is generated and transmitted to each GPU accelerator card according to the temperature information and other information to be read. In each optimized heat dissipation control cycle, a fan speed is adjusted according to the temperature information received from each GPU accelerator card.

Abstract: The application discloses a method for controlling a fan speed. The method is applied to a server including a power supply unit, a first fan, and a second fan. The method includes: obtaining a first current control data and comparing the first current control data with a second current control data.
