Fan Speed Control Mode
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. This setting
is recommended for special system confi guration or debugging. Select "Standard"
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. This setting is recommended
for regular systems with normal hardware confi gurations. Select "Optimal" for the
onboard fans to run at 30% of the Initial PWM Cycle for best power effi ciency and
maximum quietness. The options are Full Speed (@100% of PWM Cycle), Standard
(@50% of PWM Cycle), and Optimal (@30% of PWM Cycle).
CPU Temperature, System Temperature
This feature displays the current temperature of the above monitors.
Fan1 Speed
This feature displays the fan speed reading from the Fan 1 interface.
VCORE, 12V, VDIMM, 5VCC, VCC PCH, AVCC, 3.3VCC, VSB, VBAT
This feature displays the current voltages of the above voltage monitors.

ACPI Confi guration
Use this feature to confi gure Advanced Confi guration and Power Interface (ACPI)
power management settings for your system.
High Precision Event Timers
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
synchronizing multimedia streams, providing smooth playback and reducing the de-
pendency on other timestamp calculation devices, such as an x86 RDTSC Instruc-
tion embedded in the CPU. The High Performance Event Timer is used to replace
the 8254 Programmable Interval Timer. The options are Enabled and Disabled.
