Problems solved by technology

[0004] However, this often leads to the following problems: on the one hand, different CPUs have different virtual temperature values ​​corresponding to their PECIs; The corresponding error value is often not a fixed value
Therefore, these problems make it impossible to effectively and accurately control the fan speed, resulting in a problem with temperature safety

Abstract

The invention provides a temperature control system and an operating method thereof. The temperature control system comprises a main board, and the main board consists of a CPU (Central Processing Unit), a BIOS (Basic Input / Output System), a base board management controller and a fan. The BIOS detects the CPU and outputs model information in a power-on self-test process. The operation method of the temperature control system comprises the following steps: the base board management controller reads analogue temperature from the CPU; the BIOS stores at least one temperature error list; the base board management controller selects a corresponding temperature error list according to the model information and calculates the surface temperature of the CPU according to the temperature error list and analogue temperature compensation so as to output a control signal; the fan receives the control signal and runs based on the control signal to reduce the surface temperature of the CPU. By utilizing the system and method disclosed by the invention, nonlinear errors between the analogue temperature and a practical temperature can be completely eliminated, thus the safety of the temperature control of the CPU can be largely improved, and the stability of the operation of a whole system can be enhanced.

Description

technical field [0001] The present invention relates to a temperature control system and its operation method, and in particular to a temperature control system and its operation method applied on the mainboard of a computer. Background technique [0002] Due to the rapid development of the technology and communication industry, the application of information products is also becoming more and more popular, especially electronic devices such as desktops and notebook computers appear frequently in daily life. And this not only greatly improves the convenience of life, but also shortens the distance of time and space, so that everyone is no longer limited to geographical boundaries, but can make each other more closely interact and exchange a lot Information knowledge, in order to achieve the optimization of common interests. [0003] For the central processing unit (CPU) temperature sensing management method of the above-mentioned electronic devices, the platform environment...
