Qfan Configuration Qfan Tuning Click this item to automatically detect the lowest speed and configure the minimum duty cycle for each fan. CPU Q-Fan Control This item allows you to set the CPU Q-Fan operating mode. [Auto] Detects the type of CPU fan installed and automatically switches the control modes. [PWM Mode] [DC Mode] Enables the CPU Q-Fan Control feature in PWM mode for 4-pin CPU fan. Enables the CPU Q-Fan Control feature in DC mode for 3-pin CPU fan. [Disabled] Disables the Q-Fan Control. The following items appear only when you set the CPU Q-Fan Control to [Auto], [PWM Mode], and [DC Mode]. CPU Fan Step Up This item allows you to set the value of the CPU fan step up. Configuration options: [0 sec] [2.1 sec] [2.8 sec] [3.6 sec] [4.2 sec] [5.0 sec] [6.3 sec] [8.5 sec] [12 sec] [25 sec] CPU Fan Step Down This item allows you to set the value of the CPU fan step down.
