Embodiment Construction

[0025] In order to make the technical solutions and advantages of the embodiments of the present application clearer, the exemplary embodiments of the present application will be described in further detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, and Not all embodiments are exhaustive. It should be noted that the embodiments in the present application and the features of the embodiments may be combined with each other in the case of no conflict.

[0026] In the related art, in order to avoid overheating damage of a GPU (Graphics Processing Unit, graphics processor), a graphics card fan for heat dissipation is usually configured for the graphics card. During the rotation of the graphics card fan, the fan blades of the graphics card fan can speed up the air flow around the graphics card, and the heat emitted by the graphics card can be dissipated with the flowing air. ...

Abstract

Embodiments of the present application provide a control method, device, terminal, and medium for a graphics card fan, which relate to a graphics card heat dissipation technology, and are used to overcome the problem that it is difficult to achieve both good heat dissipation effect and noise reduction in related technologies. The control method includes: obtaining the current temperature of the graphics card, determining the current temperature deviation of the graphics card; the current temperature deviation is the difference between the current temperature and the set temperature; determining the pulse width modulation PWM duty cycle according to the current temperature deviation Duty ratio: when the PWM duty ratio exceeds the maximum duty ratio corresponding to the noise requirement, the speed of the graphics card fan is controlled according to the maximum duty ratio.

Description

technical field [0001] The present application relates to a graphics card cooling technology, and in particular, to a control method, device, terminal and medium for a graphics card fan. Background technique [0002] The graphics card is an important component that connects the monitor to the computer motherboard. The graphics card is used to convert the display information required by the computer system to drive the display, and provide the display with progressive or interlaced scanning signals to control the display to display correctly. The graphics card is mainly composed of a graphics card motherboard, a GPU (Graphics Processing Unit, graphics processor), a display memory, etc. The GPU is the core component of the graphics card, and is mainly used for constructing and rendering input video information. [0003] During the working process of the graphics card, the GPU will generate a large amount of heat. In order to avoid overheating and damage of the GPU, in the rel...
