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 con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 congurations. Select "Optimal" 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), Standard

(@50% of PWM Cycle), and Optimal (@30% of PWM Cycle).

CPU Temperature Display Mode

This feature displays the CPU temperature detected by DTS (i.e., +34

C) or tem-

perature status in text ("Low", "Medium" or "High"). The options are Text Mode

or DTS.

If Text Mode is selected, the CPU Temperature Display Mode will show the CPU

temperature status as follows:

Low – This level is considered as the ‘normal’ operating state. The CPU

temperature is well below the CPU ‘Temperature Tolerance’. The mother-

board fans and CPU will run normally as congured in the BIOS (Fan Speed

Control).

User intervention: No action required.

Medium – The processor is running warmer. This is a ‘precautionary’ level

and generally means that there may be factors contributing to this condition,

but the CPU is still within its normal operating state and below the CPU

‘Temperature Tolerance’. The motherboard fans and CPU will run normally

as congured in the BIOS. The fans may adjust to a faster speed depending

on the Fan Speed Control settings.
