Appendix B - CPU Fan Protection

The CPU must be kept cool by using a CPU fan with heat sink. Without sufficient air circulation across the CPU and heat sink, the CPU will overheat damaging both the CPU and system board.

The system board supports the CPU Fan Protection function. It has the capability of monitoring the CPU fan when the system boots. Once it has detected that the CPU fan did not rotate, 5 warning beeps will sound then the system will automatically power-off. This preventive measure has been added to protect the CPU from damage and insure a safe computing environment.

To use the CPU Fan Protection function, please follow the steps below.

1.Before you power-on the system, make sure the heat sink and CPU fan are correctly installed onto the CPU. The system is capable of monitoring the CPU fan, therefore you must use a fan with sense pin to support this function. Connect the CPU fan to the CPU fan connector on the system board.

2.The “CPU Fan Protection” field in the PC Health Status submenu of the BIOS must be set to “Enabled”.

3.You may now power-on the system.

Three circumstances may occur causing the system to detect CPU fan failure.

1.The CPU fan is not connected to the CPU fan connector on the system board.

2.The CPU fan may be damaged. Replace it with a new fan.

3.The CPU fan did not rotate immediately upon system boot-up or it took some time before the CPU fan rotated. Check whether the heat sink 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 will dissipate heat more efficiently, otherwise, you have to disable this function in the BIOS.
