Embodiment Construction

[0014] see figure 1 , In a preferred embodiment of the present invention, a VRM temperature regulation system includes a CPU 10 , a VRM 20 , a temperature detection module 30 , an EC (Embedded Controller, embedded control chip) 50 and a south bridge chip 60 .

[0015] The VRM20 is used to provide working voltage to the CPU10. When the utilization rate of the CPU 10 increases, the load of the VRM 20 increases, and the temperature due to the work increases.

[0016] The temperature detection module 30 is used to detect the temperature of the VRM20. The temperature detection module 30 detects the temperature of the VRM 20 at intervals.

[0017] The EC50 is connected to the temperature detection module 30 through an SMBus (System Management Bus) and includes a temperature reading module 51 , a comparison module 53 and a control module 55 .

[0018] The temperature reading module 51 is used to read the analog temperature value detected by the temperature detection module 30 and ...

Abstract

A VRM temperature adjusting system is used for adjusting the temperature of a VRM and comprises a CPU, a temperature detection module and an EC. The VRM is used for supplying a working voltage to the CPU. The temperature detection module is used for detecting the temperature of the VRM. The EC is used for receiving the temperature detected by the temperature detection module and lowering the basic frequency of the CPU when the detected temperature is equal to or higher than a maximum temperature set by the EC so that the charge capacity of the VRM can be reduced, and the temperature of the VRM can be lowered. The invention further discloses a VRM temperature adjusting method.

Description

technical field [0001] The present invention relates to a temperature regulation system and method, in particular to a VRM (Voltage Regulator Module, voltage regulation module) temperature regulation system and method. Background technique [0002] When the power supply VRM module on the computer motherboard works in a high-performance state, the temperature is very high, and sometimes it can reach more than 100 degrees Celsius. Although the current VRM part has its own temperature protection mechanism (it will turn off the voltage after reaching a certain temperature), this protection mechanism will make the computer automatically shut down or restart. Contents of the invention [0003] In view of the above, it is necessary to provide a temperature adjustment system and method capable of preventing the computer from shutting down or restarting when the temperature of the VRM module is too high. [0004] A VRM temperature adjustment system, used to adjust the temperature ...
