Intelligent adjusting method and controlling system of computer fan revolving speed

Abstract

The invention discloses an intelligent adjusting method and a controlling system of a computer fan revolving speed. The controlling system comprises a BIOS managing unit, a CPU and an embedded controller which are all connected with a control bus, the controlling system also comprises an embedded controller storage connected with the embedded controller. Through the embedded controller, the controlling system receives a BIOS program write command containing electronic component type information sent by the BIOS managing unit, and then the controlling system stores the BIOS program in the embedded controller storage. According to the intelligent adjusting method and the controlling system of the computer fan revolving speed, the types of electric components are detected after starting up the computer, then the types of the electric components are sent to the embedded controller, and then according to the types of the electric components, the embedded controller selects a heat dissipation parameter corresponding to the type of the electric component so as to control the fan. In this way, CPU heat dissipation can be adjusted by controlling a main fan and an assistant fan, and heat dissipation temperature can be controlled according to operating power of the CPU, thus a suitable operation environment for the CPU is guaranteed when the CPU is in a high temperature environment or in a high-burden operation.

Description

technical field [0001] The invention belongs to the technical field of computer control, and in particular relates to an intelligent adjustment method and control system for a computer fan speed. Background technique [0002] The computer fan has an inseparable relationship with the use and life of the computer. How to adjust the speed of the computer fan to control the heat dissipation of the computer CPU? First of all, there are usually two ways to adjust the computer fan speed control. The first is a one-size-fits-all adjustment, directly in the BIOS to manually adjust the fan speed to the highest. Many people have such a misunderstanding that the higher the wind speed, the better the cooling effect of the CPU. In fact, the consequence of this method is that long-term use will not only reduce the service life of the fan, but also cause the fan to be fully loaded. The noise caused by the operation is large, which affects the user's computer experience; [0003] The other...

Problems solved by technology

[0006] The existing embedded controller is controlled by a set of fan curves, which is not targeted. When the same product wants to occupy various markets in the market, its configuration will change accordingly, for example, changes in CPU, memory or hard disk , the internal factors that affect heat dissipation will also change, resulting in great challenges for the heat dissipation and noise of the PC, and it is difficult to achieve a suitable match
