What is the reason why the CPU fan of the industrial control computer does not rotate

There are many reasons why the CPU fan of an industrial computer does not work. Next, I will analyze various situations in detail.

When the industrial control computer is running, the CPU fan needs to be rotated all the time. If the CPU fan does not rotate, it indicates that a certain fault condition has occurred. The fan power supply is not connected; The second reason is that the machine has been in use for a long time and the fan bearing is stuck due to lack of oil.

Industrial control computer

Solution 1: Open the industrial computer chassis and check whether the power cord of the CPU fan is plugged in. "When the CPU fan power cord is plugged in, but the fan still does not rotate, you need to purchase a new fan and try replacing it.". In addition, if the high temperature fan does not rotate and only automatically alarms, then your machine should be an Intel CPU, because only Intel CPUs can withstand the high temperature caused by the fan not rotating. If it is an AMD CPU, the machine should have a black screen, a blue screen, a crash, or a CPU that directly burns out.

Solution 2: Replace a fan of the same size for ten yuan or buy a complete set of radiators for ten yuan, and the problem will be solved. Generally speaking, if the fan does not rotate, it indicates that the fan cannot operate. Bearing fans are the problem. If industrial computers use inexpensive CPU fans for a year or two, this problem may occur. The same is true for graphics card fans.

Solution 3: Generally, the top of the fan is the place where the brand label is affixed. Carefully remove it, expose the center, drop two drops of oil, and then cover the label. Of course, the best way is to replace the CPU fan. "Because if it's an old P4 fan, it's very difficult to disassemble it, and if you're not careful, you may break the fan.".

The CPU fan of industrial control computer is mainly used for CPU heat dissipation, and only when the CPU temperature is above about 70 degrees Celsius, it will rotate for heating. In addition, the problem of high backplane temperature is not necessarily caused by the CPU. The heat from hard disks, graphics cards, and motherboards can all accumulate on the CPU side. Only by properly handling the heat dissipation of the CPU fan can the industrial control computer work properly. Therefore, when purchasing an industrial computer, it is also necessary to pay attention to its heat dissipation performance.
