Three-Fan Status Monitors with Firmware/Software On/Off
Control
The PC health monitor can check the RPM status of the cooling fans. The
thermal fans are controlled by the overheat detection logic.
Please Note: The
tachometer readings are for JT1, JT2 and JT3 only
.
Environmental Temperature Control
A 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 thresh-
old. 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 is activated when the power is turned on. It can be turned off when
the CPU is in sleep mode. When in sleep mode, the CPU will not run at full
power, thereby generating less heat. For power saving purposes, the user has
the option to shut down the CPU fan.
System Overheat Alarm, LED and Control
This feature is available when the user enables the system overheat warning
function in BIOS (see page 5-18). The overheat alarm will activate when the
system temperature exceeds the temperature threshold configured by the user.
When the overheat alarm is activated, both the overheat fan and the warning LED
are triggered. Note: The alarm, fan and LED will remain on until the com-
puter is restarted.
Chassis Intrusion Detection
The chassis intrusion circuitry can detect unauthorized intrusion to the system.
The chassis intrusion connector is located on JL1. Attach a microswitch to JL1.
When the microswitch is closed, it means that the chassis has been opened.
The circuitry will then alert the user with a warning message when the system
is turned on. This feature is available when the user is running Intel's LANDesk
Client Manager and SUPERMICRO's Super Doctor.
