Method for controlling rotate speed of computer cooling fan and system thereof

Abstract

This invention discloses one computer cooling fan rotation control method and its system, which comprises the following steps: in temperature control chip orderly setting first to third temperatures for lower one and high one; establishing temperature and fan rotation conversion relationship list for memory in chip; the lower part, fan rotation and temperature change acceleration inclination is larger than current linear rate; the CPU inner temperature sensor real time tests its inner temperature; receive module receives the inner temperature; the process module according to current inner temperature through inside temperature for relative fan rotation speed data; control module controls the fan rotation speed according to fan rotation speed data; the match system comprises one CPU sensor, one temperature control chip; the temperature control chip also comprises one receive module, one process module and one control module.

Description

【Technical field】 [0001] The present invention relates to a method and system for controlling the speed of a computer cooling fan, in particular to a computer cooling fan that can respond quickly to temperature changes at the initial stage of the temperature rise of the central processing unit and can effectively suppress the temperature rise trend Speed ​​control method and system thereof. 【Background technique】 [0002] With the continuous popularization of computers, computers bring convenience to people's daily life and work, but there are common problems in the use of the CPU temperature that are too high, resulting in crashes and obvious slowdown of the machine speed. For some overclocked Users are more visible. The central processing unit is the heart of the computer. If it works in such a harsh environment for a long time, the parameters of the central processing unit of the computer will not be guaranteed. Especially in today's rapid development of science and tec...

In this way, in the initial stage of temperature rise, it is impossible to respond quickly to temperature changes, and the trend of temperature rise cannot be effectively suppressed. Instead, it can only be controlled by further increasing the speed as the temperature rises.

Such a design is relatively simple, and no more control is required after setting the corresponding registers, but its disadvantage is that it only increases the fan speed slowly as the temperature rises, and cannot quickly reduce the chip temperature, making the chip in a high temperature state for a long time. Due to the characteristics of semiconductor silicon chips , which reduces the life of the chip and increases the instability
