1-4 PC Health Monitoring
This section describes the PC health monitoring features of the SUPER 370SBA,
370SBM, 370SLA and 370SLM. All have an onboard System Hardware Monitor
chip that supports PC health monitoring.
Seven Onboard Voltage Monitors for the CPU Core(s), CPU I/
O, +3.3V,
±±±±±
5V, and
±±±±±
12V
The onboard voltage monitor scans these seven monitored voltages continuously.
Once a voltage becomes unstable, it will give a warning or send an error message
to the screen. Users can adjust the voltage thresholds to define the sensitivity
of the voltage monitor.
Note: -5V is not required when using a microATX (SFX) power supply.
Three-Fan Status Monitors with Firmware/Software On/Off
Control
The PC health monitor can check the RPM status of the cooling fans. The
onboard 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.
Environmental Temperature Control
The thermal control sensor monitors the CPU temperature in real-time and will
turn on a back-up fan whenever the CPU temperature exceeds a user-defined
threshold. The overheat circuitry runs independently from the CPU. It can
continue to monitor for overheat conditions even when the CPU is in sleep mode.
Once it detects that the CPU temperature is too high, it will automatically turn
on the back-up fan to prevent any overheat damage to the CPU. The onboard
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 activates when the power is turned on. It can be turned off when
the CPU is in sleep mode. When in sleep mode, the CPU does not run at full
power, and thereby generates less heat. For power saving purposes, the user
has the option to shut down the CPU fan.
