2.7.4 Q-Fan Configuration The subitems in this menu allows you to configure the Q-Fan features. Q-Fan Tuning Click [OK] button to detect the lowest speed and configure the minimum duty circle for each fan. Do not shut down or reset your system during the tuning progress. Configuration options: [Ok] [Cancel] CPU Q-Fan Control [PWM Mode] [Disabled] Disables the CPU Q-Fan control feature. [PWM Mode] Enable the CPU Q-Fan control in PWM mode for the 4-pin CPU fan. CPU Fan Speed Lower Limit [200 RPM] This item appears only when you enable the CPU Q-Fan Control feature and allows you to disable or set the CPU fan warning speed. Configuration options: [Ignore] [200RPM] [300 RPM] [400 RPM] [500 RPM] [600RPM] CPU Fan Profile [Standard] This item appears only when you enable the CPU Q-Fan Control feature and allows you to set the appropriate performance level of the CPU fan. [Standard] Sets to [Standard] to make the CPU fan automatically adjust depending on the CPU temperature. [Silent] Sets to [Silent] to minimize the fan speed for quiet CPU fan operation. [Turbo] Sets to [Turbo] to achieve maximum CPU fan speed. [Manual] Sets to [Manual] to assign detailed fan speed control parameters. The following four items appear only when you set CPU Fan Profile to [Manual]. CPU Upper Temperature [70] Use the and keys to adjust the upper limit of the CPU temperature. The values range from 25ºC to 75ºC. CPU Fan Max. Duty Cycle(%) [100] Use the and keys to adjust the maximum CPU fan duty cycle. The values range from 20% to 100%. When the CPU temperature reaches the upper limit, the CPU fan will operate at the maximum duty cycle. CPU Middle Temperature [25] Use the or keys to set the value for CPU Middle Temperature. The range of the values depends on the CPU installed. CPU Fan Middle Duty Cycle(%) [20] Use the or keys to adjust the CPU fan middle duty cycle. The values range from 20% to 100%. When the CPU temperature reaches the upper limit, the CPU fan operates at the maximum duty cycle. CPU Lower Temperature [20] Use the or keys to adjust the CPU fan's lower temperature. The values range from 0°C to 75°C. Chapter 2: BIOS information 2-26
