Method 1: CPU fan power failure. Under normal circumstances, CPU fan is powered by motherboard, and power supply interface is on fan cable. If you find that cable is loose, you can try reconnecting it and pushing it firmly into interface. If CPU fan returns to normal, issue is resolved. If CPU fan still won't turn on, try plugging power cable into another identical power interface.

Method 2: The CPU fan is clogged with dust. If desktop is used for a long time without cleaning it, it will cause dust to accumulate on CPU fan and block operation of fan blades.
