1-2 PC Health Monitoring
This section describes the PC health monitoring features of SUPER
P6SLA/P6SLE. It has an on-board W83781D System Hardware
Monitor chip which can support PC health monitoring.
Seven On-Board Voltage Monitors for the CPU Core, CPU I/O,
+3.3V, ±5V, and ±12V
The on-board voltage monitor will scan the seven monitored
voltages every second. Once a voltage becomes unstable, it will
report a warning or an error message on the screen. Users can
adjust the threshold of the monitored voltage to determine the
sensitivity of the voltage monitor.
Three-Fan Status Monitors with Firmware/Software Control On/
Off
The PC health monitor can check the RPM status of the cooling
fans. The on-board 3-pin CPU fan is controlled by the ACPI BIOS
and the ACPI enabled operating system. The thermal fans are
controlled by the overheat detection logic.
Environment Temperature Control
The thermal control sensor will monitor the real-time environment
temperature. It will turn on the back-up fan whenever the environ-
ment temperature goes over the user-defined threshold. The
overheat circuitry runs independently from the CPU . It can still
monitor the overheat condition even if the CPU is in sleep mode.
Once it detects that the environment temperature is too high, it
will automatically turn on the back-up fan to prevent any overheat
damage to the CPU. The on-board chassis thermal circuitry can
monitor the overall system temperature and alert users when the
chassis temperature is too high.
CPU Fan Auto-Off in Sleep Mode
The CPU fan will turn on when the power is on. It can be turned
off when the CPU is in sleep mode. When the CPU is in sleep
mode, it means that it will not run at full power, thereby generat-
ing less heat. For power saving purposes, the user can have the
option to shut down the CPU fan.
CPU Overheat Alarm and Control
This feature is available when used with SUPERMICRO's SUPER
Doctor Utility. The program will generate a beep sound via the
