Control device and method for starting fan when computer start

Abstract

A method for controlling start-up fan when computer is started up includes utilizing start-up state identification unit to identify out start-up state of computer and sending said state to control unit then starting fan up by control unit at different start-up intensity according to different start-up state and simultaneously utilizing temperature fetch unit to fetch out temperature of computer and sending temperature data to control unit then starting fan up by control unit at different driving intensity according to different start-up state and different temperature when computer is started up.

Description

technical field [0001] The present invention mainly relates to the technical field of computer heat dissipation, in particular to a fan control device and method for starting a computer system. Background technique [0002] Computer heat dissipation system is an important part of modern computer systems, especially with the development of high-speed computer technology, the central processing unit (CPU) main frequency and power consumption continue to increase, the importance of heat dissipation technology has become increasingly prominent, but the general heat dissipation process will Noise is generated, and computer users need to complete various operations in a quiet and comfortable environment, so the noise control technology of computers is also particularly important. [0003] In order to achieve the desired heat dissipation effect and control the noise of the fan, many methods have been considered. The most common method is to dynamically adjust the speed of the fan a...

But its disadvantages are also obvious. On the one hand, this method has high requirements on the fan. The fan needs a smaller damping coefficient and a fan with better quality, which virtually increases the cost of the computer system; on the other hand, using This method makes the computer’s heat dissipation ability very poor when it is started, especially during the system restart process, when the temperature of the inner surface of the system is too high, it is easy to cause the computer to crash, and even cause physical damage to the internal components of the computer.

[0010] Therefore, the methods of temperature control and noise control used to start the fan when the computer system is started at present have disadvantages in varying degrees. But it can't fundamentally solve the above shortcomings
