Server heat dissipation and Linux temperature detection, linux Temperature
When the server is placed in poor cooling conditions, this will lead to premature damage to the hard drive, and other components of the server will soon fail. When a modern server motherboard detects that the CPU is overheated, it usually limits the CPU frequency, so even if the server is not completely damaged, it may reach an unusable level. Sometimes, component overheating may cause the process to crash unexpectedly. If the data center is overheated, you can purchase a mounted thermometer that can detect the temperature. Linux provides the lm-sensors package tool. Sensors is a call detection sensor, it is used to detect the temperature of each part of the server. sh-c "yes | sensors-detect" is used to set all detection options to yes single sensors-detect to set sensing detection, you need to input a lot of yes to use sensors to output the temperature and voltage of many parts.
What should I do if the server temperature is too high? We can check the air temperature around the server to ensure that there is no dust inside or outside the server vent. If the server is in a cold air from the bottom to the data center, you can consider moving the server that is particularly popular closer to the floor. It can also increase the interval between servers to prevent servers from getting too close. If a server is stacked up and down with a partition instead of using a rack to place the server, the air flow will be bad and the server will be overheated.
Linux heat dissipation Problems

First, look for settings such as "Power Management" to see if the settings are correct;
Look for acpid and so on, and check whether it is installed or not.

The radiator is not hot, but the detected cpu temperature is very high.

Change the temperature of several types of software.

If the radiator is hot, the landlord's CPU will soon be burned out.

The problem may be that the CPU radiator base is not closely integrated with the CPU. If the silicon grease becomes hard, it should be scraped off and the new silicon grease should be applied again. Buy the kind of silica gel with silver powder. A more direct point is to replace the radiator. About 100 yuan of super-frequency three East China Sea is very good.
