The computer host has the sound of thin wires passing through the metal inner wall, but it does not affect the normal use. What's going on here?
It's usually the sound of a fan. The fan will fail if it is used for a long time. After all, high speed, dust and wear will all be like this. In addition, if the fan blade scratches the wire, there will be abnormal noise. Fan failure, if the temperature is not too high, will not have any impact on the use. Including power supply, graphics card, chassis and CPU fan. It is best to check the abnormal sound clearly to avoid the expansion of the fault.
