System Health Monitor
CPU Overheat Temperature
Use the "+" and "-" keys to set the CPU temperature threshold to between 65
o
and 90
o
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
setting is 78
o
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 con-
trolled 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 chassis came with 3-pin fan
headers. Select "4-pin" if your chassis came with 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 to allow 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).
Note: the 4-pin fan speed settings are not available for the H8DAR-8 and
H8DAR-i, which have 3-pin fan headers.
FAN1 Speed through FAN8 Speed
The speeds of the onboard fans (in rpm) are displayed here.
Note: the FAN1 through FAN5 speeds will be displayed for the H8DAR-8 and
H8DAR-i.
