Do you have the following things visible in the bios

"Target CPU Temperature"

"Target Fan Speed"

Have you tried disabling it then rebooting then enabling it again and rebooting?

havent mate not sure how to do that do you mean disable the fan or disable something else

In the bios disable CPU Quiet Fan save settings then allow pc to boot up then reboot and change back to enabled also check Target CPU Temperature & Target Fan Speed settings the allow to boot up.
