CPU Overheat Temperature

Use the "+" and "-" keys to set the CPU temperature threshold to between 65

and 90

C. When this threshold is exceeded, the overheat LED on the chas-

sis 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 72

The other items in the submenu are all systems monitor displays for the follow-

ing information:

CPU1 Temperature, CPU2 Temperature (for dual CPU systems), System Tem-

perature, CPU1 Vcore, CPU2 Vcore (for dual CPU systems), +5 Vin, +12Vin,

-12V Vcc, DDRA VTT, DDRB VTT, 1.2V for Hyper-Transport, 2.5V, 5V standby,

2.5V standby and battery voltage.

 System Fan Monitor

Fan Speed Control Modes

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

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 and 2) 3-pin (Server).

FAN1 Speed through FAN5 Speed

The speeds of the onboard fans (in rpm) are displayed here.
