X7DBU/X7DGU User's Manual
the PECI Agent is still within its normal operating state and below its ‘Temperature
Tolerance’. The cooling fans will run normally as confi gured in the BIOS. The fans
may adjust to a faster speed depending on the Fan Speed Control settings.
User intervention: No action is required. However, consider checking the cooling
fans and the chassis ventilation for blockage.
High – The PECI Agent is running hot. This is a ‘caution’ level since the PECI
Agent ’s ‘Temperature Tolerance’ has been reached (or has been exceeded) and
may activate an overheat alarm. The system may shut down if it continues for
a long period to prevent damage to the PECI Agent.
User intervention: If the system buzzer and Overheat LED has activated, take
action immediately by checking the system fans, chassis ventilation and room
temperature to correct any problems.
System Temperature
This item displays the absolute system temperature status as detected by the
BIOS:
Fan1-Fan8 Speeds
If the feature of Auto Fan Control is enabled, the BIOS will automatically display
the status of the fans indicated in this item.
Fan Speed Control Modes
This feature allows the user to decide how the system controls the speeds of the
onboard fans. The CPU temperature and the fan speed are correlative. When the
CPU on-die temperature increases, the fan speed will also increase, and vise versa.
If the option is set to 3-pin fan, the fan speed is controlled by voltage. If the option
is set to 4-pin, the fan speed will be controlled by Pulse Width Modulation (PWM).
Select 3-pin if your chassis came with 3-pin fan headers. Select 4-pin if your chas-
sis 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 fan speed control and allow the onboard fans to constantly run at full speed
(12V). The Options are: 1. Disable (running@Full Speed), 2. 3-pin (Server), 3.
3-pin (Workstation), 4. 4-pin (Server) and 5. 4-pin (Workstation).
Voltage Monitoring
The following items will be monitored and displayed:
Vcore A/Vcore B, -12V/+12V, P1V5/CPU_VTT/Vbat, +3.3V, 5Vsb/5VDD
