The Important Computer Components CPU Introduction

So far no single cpu cooling system to ensure that never fail. Cooling computer components lost umbrella of "core", often within a few seconds will never stop "beating." Fortunately, the smart engineers have developed effective CPU temperature monitoring, protection technology. Special and sensitive to the "smell" at any time to monitor CPU temperature changes, and provide the necessary protection measures to enable the CPU from the high temperature extreme vulnerability.More information you can know by tradetang.com.

CPU power consumption and temperature with the acceleration and speed increasing, has become a truly a "hot potato." How to make CPU safe operation, improve system reliability, prevent overheating caused by the crash, blue screen, repeatedly re-start or even computer memory card burn, not only the difficulties faced by the CPU, motherboard designers also left an important issue. To this end, Intel first proposed a temperature monitoring device (Thermal Monitor) concept, through to the CPU temperature control and overheating protection to significantly increase the stability and security.

CPU temperature monitoring system established, we must first select a suitable temperature measurement device. The device can measure temperature, there are many, such as thermistor, thermocouple, and semiconductor temperature sensors. The first computer to use the thermistor as the computer usb hubs , CPU socket or strip the ball under the erection of a small component that is thermistor.

The core issue of computer earphones heat from the CPU chip package to the external cooling, CPU core temperature, surface temperature and between about 15 ℃ ~ 30 ℃ temperature difference, while different forms for chip packaging, and environmental differences in temperature and is difficult to determine. So far no single technology can bring to the thermistor embedded in chip, resulting in the CPU thermistor can measure surface temperature, core temperature can not be measured.

For now, both use the Intel or AMD's CPU, has been rarely used CPU thermistor measuring the surface temperature, so the BIOS and test the computer speakers software shows the CPU temperature is that the core temperature of CPU. In the Pentium Ⅱ ago, CPU temperature usually refers to the surface temperature; Pentium Ⅱ and beyond are integrated within the CPU thermal diode, temperature is measured core temperature. However, during the transition period are still a number of the motherboard CPU socket thermistor kept below, so that could be detected simultaneously in two different CPU temperature, BIOS usually display the CPU's external temperature, and detection software test the core temperature.
