X8SIA/X8SIA-F

Supermicro 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., 25

C).

The information provided above is for your reference only. For more information on

thermal management, please refer to Intel’s Web site at www.Intel.com.

Fan1 ~ Fan5 Reading

This feature displays the fan speed readings from fan interfaces Fan1 through

Fan5.

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 recommended for special system conguration 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 recommended 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 congurations. Select Energy Saving for the onboard

fans to run at 30% of the Initial PWM Cycle for best power efciency and maximum

quietness. The Options are: Full Speed (@100% of PWM Cycle), Performance

(@70% of PWM Cycle), Balanced (@50% of PWM Cycle), and Energy Saving

(@30% of PWM Cycle).

CPU Vcore, AVCC, 3.3Vcc, 12V, V_DIMM, 5V, -12V, 3.3Vsb, and Vbat

This feature displays the voltage readings for the described components.

ACPIConguration

Use this feature to congure Advanced Conguration and Power Interface (ACPI)

power management settings for your system.

High Performance Event Timer

Select Enabled to activate the High Performance Event Timer (HPET) that produces

periodic interrupts at a much higher frequency than a Real-time Clock (RTC) does in
