What temps are you getting? Your motherboard has CPU Quiet Fan.Is this enabled in the bios (see page 41 of the online manual)

"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.
