Current CPU Temperature, Current CPU Fan Speed and Current
AGP Fan Speed
These fields show the current temperature of the processor, and the
current fan speed of the CPU and AGP fans 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 (70oC/158o 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 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.
