• Monitors processor temperature and overheat alarm.
If the temperature of the processor is over 85 o C, an alarm will
sound and the Green LED will illuminate warning you of system
overheat.
Some of the most common causes leading to high temperature
are:
- The fan is not functioning normally or has stopped. Turn off
your system and replace the fan.
- The space clearance of the processor, fan and heat sink is
inadequate to maintain proper airflow and heat dissipation.
Refer to the Clearance Requirements section in Chapter 3 of
this manual.
- The chassis or cabinet has poor ventilation.
• 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 irregularity.
Some of the most common causes leading to unstable output
voltage of a power supply are:
- The power supply is not functioning normally. Turn off your
system and replace the power supply.
- The AC input from the power outlet to your system is
unstable.
• Automatic processor fan control to save energy, prevent system
overheat, prolong fan life and implement silent system.
With the system’s power switched on, the processor’s fan will
rotate only if the temperature of the processor is over 25 o C
(±10%).
