with sense pin to support this function. Connect the CPU fan to
the 3-pin fan connector at location J16 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 rotate,
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 dissipate heat more
efficiently, otherwise, you have to disable this function in the “CPU
Fan Protection” field (PC Health Status submenu) of the BIOS.
