with sense pin to support this function. Connect the CPU fan
to the 3-pin fan connector at location J10 on the system
board.
2. Make sure the “CPU Fan Protection” field in the PC Health
Status submenu of the BIOS is set to “Enabled”. Refer to PC
Health Status section in chapter 3 for more information.
3. You may now power-on the system.
Two circumstances may occur causing the system to power-off
automatically. A beeping alarm will sound before the system will
power-off.
1. The CPU fan did not rotate because the CPU fan is damaged.
When you boot-up the system and the CPU fan did not ro-
tate, it may indicate that the fan is damaged. Replace it with a
new fan.
2. The CPU fan did not rotate immediately upon system boot-
up or it took some time before the CPU fan rotated.
If the CPU fan did not rotate immediately upon system boot-
up or it took some time before the fan rotated, check
whether the heatsink and fan are mounted properly onto the
CPU then restart the system. If the same problem occurs, you
must replace it with a good quality fan - one that will rotate
immediately once power comes in and also one that can dis-
sipate heat more efficiently, otherwise, you have to disable this
function in the “CPU Fan Protection” field (PC Health Status
submenu) of the BIOS.
