1-2 PC Health Monitoring
This section describes the PC health monitoring features of SUPER
P5MMA98/P5MMS98/P5MMA2/P5MMS2. SUPER P5MMA98 and
P5MMS98 have an LM78 chip which can support additional PC
health monitoring features. Refer to the previous section for a more
detailed specifications list.
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 volt-
ages 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.
The thermal fans are controlled by the overheat detection logic.
CPU/Chassis Temperature Control
The thermal control sensor located underneath the CPU will moni-
tor the real-time CPU temperature. It will turn on the back-up fan
whenever the CPU temperature goes over the user-defined thresh-
old. 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 CPU temperature is too high, it will
automatically turn on the back-up fan to prevent any overheat dam-
age to the CPU. The on-board chassis thermal circuitry can moni-
tor the overall system temperature and alert users when the chas-
sis temperature is too high.
