586ITXD System Board User’s Manual
Current CPU Temperature and Current CPU Fan Speed
These fields show the current temperature of the processor and the
current fan speed of the processor’s fan in RPM (Revolutions Per
Minute).
CPU Temperature Limit
This field allows you to manually set a limit to the processor’s
temperature. If the temperature of the processor is over the
temperature set in this field (70
o
C/158
o
F recommended), an alarm will
sound warning you of system overheat. The sound of the alarm is
continuous low to high beeps. 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.
- The chassis or cabinet has poor ventilation.
CPU Fan Speed Limit
This field allows you to manually set a limit to the speed of the
processor’s fan. If the processor’s fan speed is under the speed set in
this field, an alarm will sound informing you to attend to any issue that
may damage your system. The sound of the alarm resembles that of
the siren of an ambulance.
Chipset Voltage, +3.3V, +5V and +12V Voltages
Set these fields to “Monitor” if you want the system board to detect
the chipset’s voltage and output voltage of the power supply. If the
output voltage of the power supply is over or under +3.3V/+5V/
+12V (±10%), an alarm will sound warning you of voltage issue. The
sound of the alarm is continuous low to high beeps but shorter than
the temperature alarm. 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.
