im running a ruby orb fan on my pc i built its a xfx 8200 mobo with amd athlon 64 x2 dual core processor 5800+ with american megatrend bios and for some reason my cpu fan wont shut off.......like i run the computer and i shut it down then wait some time and nothing so i have to manually turn it off from the power supply im wondering if anyone knows how to work with this bios to maybe fix this
