System Health Monitor

CPU Overheat Temperature
Use the "+" and "-" keys to set the CPU temperature threshold to between 65
o
and 90 C. When this threshold is exceeded, the overheat LED on the chassis
will light up and an alarm will sound. The LED and alarm will turn off once the
CPU temperature has dropped to 5 degrees below the threshold set. The default
o
setting is 78 C.
The other items in the submenu are all systems monitor displays for the following
information:
CPU1 Temperature, CPU2 Temperature (for 2U systems), System Temperature,
CPU1 Vcore, CPU2 Vcore (for 2U systems), 3.3V Vcc, +5 Vin, +12Vin, -12V Vcc,
DDRA VTT, DDRB VTT, 1.2V for Hyper Transport, DIMM Voltage, 1.8V for chipset,
5V Standby and 3.3V Standby.

System Fan Monitor

Fan Speed Control Modules
This feature allows the user to determine how the system will control the speed
of the onboard fans. If the option is set to "3-pin fan", the fan speed is controlled
based upon the CPU die temperature. When the CPU die temperature is higher,
the fan speed will be higher as well. If the option is set to "4-pin", the fan speed
will be controlled by the Thermal Management Settings pre-confi gured by the
user with this setting. Select "3-pin" if your motherboard has 3-pin fan headers.
Select "4-pin" if your motherboard has 4-pin fan headers. Select "Workstation"
if your system is used as a Workstation. Select "Server" if your system is used
as a Server. Select "Disable" to disable the fan speed control function and force
the onboard fans to continuously run at full speed (12V). The options are 1)
Disable, Full Speed, 2) 3-pin (Server), 3) 3-pin (Workstation), 4) 4-pin (Server)
and 5) 4-pin (Workstation).
