I am stuck in a weird problem. The CPU fan just works fine when I start my PC. But after sometime maybe half an hour the CPU fan runs extremely slow like for example it goes from (RPM 5000 to 150). This is only for the reference because I does not know exact RPM of my CPU fan. This cause overheating in the processor and power down the PC. It happens every time.

1How did you verify that the shutdown is due to overheating?– AlbinCommented Dec 25, 2019 at 5:47

There seems to be a mechanical problem with the CPU fan that is causing it to malfunction and spin too slowly. It's much cheaper to replace a CPU fan than to replace the CPU. Stop using that computer and replace the CPU fan immediately before something else breaks.
SpeedFan is a system monitor for Microsoft Windows that can read temperatures, voltages and fan speeds of computer components. It can change computer fan speeds depending on the temperature of various components.
