Description of the invention α)-Field of the invention: The present invention relates to a temperature monitoring device used in the shell of a computer system. BACKGROUND OF THE INVENTION: In a general computer system, a large number of electronic circuit components are included, and most of these components are mounted on a printed circuit board (P 1 a s t i c C i r c u i t B 0 a r d) in the form of integrated circuits to save space. However, due to the continuous increase in the density of integrated circuits and the continuous acceleration of computer computing speeds, the heat dissipation problem of integrated circuits in computers has become increasingly serious, and because of this, integrated circuits have become the main heating source in computer systems. At present, the cooling method for integrated circuits in computers is mainly air cooling. The air cooling method uses a metal heat sink to make intimate contact with the surface of the integrated circuit. A heat dissipation fan is provided on the heat sink. With the assistance of the heat sink and the fan, the heat emitted by the integrated circuit can be discharged to the computer case. Inside. The heat inside the computer case is discharged to the environment outside the computer case by a case fan installed on the surface of the computer case. However, in current computer systems, the speed of the fan is fixed, and the aforementioned air-cooled heat dissipation method is only for integrated circuits with large heat generation. When the workload of the computer system continues to increase, the power consumption of the integrated circuit increases, and the temperature also increases. At this time, what may happen is that the cooling fan on the heat sink cannot continuously discharge the heat emitted by the integrated circuit to Inside the housing, heat is accumulated in the heat sink or integrated circuit. Or the case fan on the surface of the computer case cannot exhaust the heat from the case to the outside of the case, resulting in heat accumulation.

Description of the invention (2), built into the computer case. From the foregoing situation, it can be known that the traditional heat dissipation method is liable to cause the temperature inside the integrated circuit and the computer case to be too high due to the lack of the heat dissipation system. The main reason for this phenomenon is that the shell fan and the cooling fan on the heat sink cannot efficiently discharge the heat from the integrated circuit and the heat inside the computer case with the heat generated by the computer system heat source. Although such a problem can be solved by using a fan with a large air volume, it will cause a lot of noise and unnecessary power consumption, which will cause discomfort to the user and waste energy. The problem that the aforementioned heat cannot be exhausted will eventually lead to the damage of the computer system and seriously affect the reliability of the computer system. Object and summary of the invention: In view of the above-mentioned background of the invention, the conventional computer system heat sink device has many shortcomings. The present invention relates to a temperature monitoring and control system used in the computer system casing. This system can solve the problem of heat dissipation of integrated circuit of current computer system, and it can also solve the problem of heat dissipation of computer case. For the purpose of the present invention, the computer system can avoid the instability of the computer system due to the excessive heat that cannot be discharged outside the casing, thereby reducing its reliability. Yet another object of the present invention can be widely applied to electronic devices that require heat dissipation, thereby improving the life of electronic products. According to the above-mentioned object, the present invention provides a computer temperature monitoring control system. In addition to the original heat sink, the cooling fan on the heat sink, and the housing fan, a number of temperature sensors, monitoring circuit boards and operating interfaces are added.The temperature of the heating source is transmitted to the monitoring circuit through the temperature sensor.
