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 and AGP Fan Speed Limit
These fields allow you to manually set a limit to the speed of the
CPU and AGP fans. If the CPU/AGP fan speed is under the speed
set in these fields, 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. The "failure detection"
circuit requires a fan to operate at greater than 3600 RPM.
+3.3V, +5V and +12V Voltages
Set these fields to "Monitor" if you want the system board to detect
the output voltage of the power supply. If the output voltage 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.
Please consult your MIS department or an electrician.
