Abstract

The present invention relates to a computer temp.-controlled equipment and its method. Said method includes the following steps: utilizing PU temp. fetch device to fetch CPU temp. at regular time, using control device to compare said temp. with temp. threshold value, according to the compared result outputting two temp. control voltage signals, the fan control device of CPU can utilize one voltage signal to regulate CPU fan rotating speed, at the same time utilizing a selector to selectively output temp. control voltage and higher voltage selected from voltages correspondent to power supply temp. measured by temp.-measuring device in the power supply interior, and utilizing power supply fan rotating speed control device and outputted higher voltage to control power supply fan rotating speed.

Description

technical background [0001] The invention relates to the computer field, in particular to a computer temperature control device and method. Background of the invention [0002] At present, the performance of the computer system is getting higher and higher, and the speed is getting faster and faster. At the same time, it will generate a lot of heat. This heat must be dissipated in time, otherwise it will seriously damage the components and affect the performance of the device. Therefore, increasing the size of the fan And speed and other aspects to improve the heat dissipation effect. However, while improving the heat dissipation effect, a large amount of noise is subsequently generated, and there is a contradiction between heat dissipation and noise. Contents of the invention [0003] The present invention proposes a system temperature control device and method aimed at the problems of system heat dissipation and noise. The BIOS is used to regularly monitor the temperatu...
