Damage Free Intelligence
Damage Free Intelligence is a feature we have added to the
system board to warn users of some classes of hardware related
problems. It is a warning system on the system board that plays a
tune/music if certain hardware problems are detected.
• CPU Slow Down
The system board is capable of monitoring the temperature of
the processor. If the processor's fan fails to function or the
temperature of the processor exceeds 85 o C, the system will
decrease CPU utilization by slowing down the CPU clock.. This
will prevent the processor from being damaged.
• Monitors processor temperature and overheat alarm
If the temperature of the processor exceeds 85 o C, an alarm
will sound and the Green LED will illuminate warning you of
system overheat.
• Monitors 5V and 12V power voltages and failure alarm
The system board is able to detect the output voltage of your
power supply. If the output voltage is over or under 5V or
12V (±10%), an alarm will sound warning you of voltage ir-
regularity.
• Automatic processor fan control to save energy, prevent sys-
tem overheat, prolong fan life and implement silent system.
The processor’s fan will rotate only if the temperature of the
processor is over 25 o C.
Important:
To use the fan control feature, you must connect your
heatsink’s fan directly to the fan connector located on the
system board. Please refer to Chapter 2 for details.
Warning Tune/Music
When you hear some tune/music from the PC speaker, you may
think it is a virus but it may not be the case (but you should still
scan your hard drive to double check).
