Many users will encounter the problem of computer overheating. After checking, they find that the computer cooling fan does not work. What is going on? Let’s look at the reasons why the cooling fan cannot work together with the cooling fan manufacturer:
Check the CPU fan and wiring, and use the replacement method to troubleshoot the power supply. If the computer can start, generally speaking, the possibility of a power supply problem is very small. At this time, the computer's cooling fan may not run due to the effect of automatic temperature adjustment.
If there is less dust, it means that there is a problem with the power supply circuit or the fan itself. Use a fan to try. If it is normal that your fan is broken, then change it. If the new fan does not work, it must be on the motherboard. There is a problem with the pins.
Some of the IBM machines start to rotate the fan, and then automatically stop after a few seconds. After working for a period of time, due to the increase in CPU temperature, they start to rotate again. If the fan rotates when it is turned on, but does not rotate later, if the fan has too much dust, clean the dust and add oil to the bearing.
Unplug the graphics card and install it to see if the fan does not turn. If it does not turn, it means that the graphics card has a problem with the power supply of the cooling fan. You must take the after-sales service. If the fan socket on the motherboard can match, you can plug it into the motherboard. You can also plug in the power source.
