Excuse me, when my notebook is playing games, Master Lu shows that the cpu temperature is 90 degrees, but the air outlet and fuselage are not very hot. What happened?

1, the test result may be inaccurate. Master Lu or other similar software does not directly measure the temperature of the equipment. After the temperature is measured by the temperature sensor built in the CPU, the temperature value is transmitted to the register of the motherboard I/O chip. Master Lu and other software only read this temperature value from the I/O chip register. However, the motherboard may use various types of I/O chips, and the I/O chips of various brands (common brands such as Winbond and ITE) are constantly improving and updating. Therefore, it is impossible for any database of test software to contain the information of all brands and models of chips, and naturally it is impossible to guarantee the accuracy of reading data from the specified register address. The same is true of other accessories, such as graphics cards and hard disks. Especially in the face of newer hardware, the probability of inaccurate measurement is relatively large. On the other hand, there may be errors in the temperature sensor of the hardware itself. Therefore, some devices can measure the temperature value more accurately, while others can't. 2. Several common test softwares, such as Everest, Rivatuner, Master Lu, Fumak, etc. , all in degrees Celsius, in degrees-days. Off-topic: the 60-degree electron migration problem mentioned by LS is mainly aimed at the old CPU and old graphics card with aluminum connection technology. Because light metal atoms will fly out after being hit by electrons, this phenomenon is called electron migration. However, since 2002, the current connection technology has basically changed to copper connection technology for heavy metals. Therefore, the temperature resistance of CPU or graphics card has been improved a lot, and the problem of electronic migration almost no longer occurs.
