RMC 7182
1U Rackmount System
(i.e., by increasing CPU Fan speed, triggering the Overheat Alarm, etc). Since CPUs can have differ-
ent 'Tem- perature Tolerances', the installed CPU can now send its 'Temperature Toler- ance' to the
motherboard resulting in better CPU thermal management.
Acnodes has leveraged this feature by assigning a temperature status to certain thermal conditions in
the processor (Low, Medium and High). This makes it easier for the user to understand the CPU's
temperature status, rather than by just simply seeing a temperature reading (i.e., 25oC).
The information provided above is for your reference only. For more information on thermal manage-
ment, please refer to Intel's Web site at www.Intel.com.
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 for effective system cooling. Select Full Speed to allow the onboard fans
to run at full speed (of
100% Pulse Width Modulation Duty Cycle) for maximum cooling. The Full Speed setting is recom-
mended for special system configuration or debugging. Select Performance for the onboard fans
to run at 70% of the Initial PWM Cycle for better system cooling. The Performance setting is recom-
mended for high-power- consuming and high-density systems. Select Balanced for the onboard fans to
run at 50% of the Initial PWM Cycle in order to balance the needs between system cooling and power
saving. The Balanced setting is recommended for regular sys- tems with normal hardware configura-
tions. Select Energy Saving for the onboard fans to run at 30% of the Initial PWM Cycle for best power
efficiency and maximum quietness. The Options are: Full Speed (@100% of PWM Cycle), Perfor-
mance (@70% of PWM Cycle), Balanced (@50% of PWM Cycle), and Energy Saving (@30% of
PWM Cycle).
Fan1 ~ Fan 5 Reading
This feature displays the fan speed readings from fan interfaces Fan1 through
Fan5. Vcore, AVCC, 3.3Vcc, 12V, V_DIMM, 5V, -12V, 3.3Vsb, and Vbat
XACPI Configuration
Use this feature to configure Advanced Configuration and Power Interface (ACPI) power management
settings for your system.
USB Device WakeUp
This feature is used to awaken from Standby mode by a Universal Serial Bus (USB) device (such as, a
USB mouse or USB keyboard). The options are Enabled and Disabled.
