ASUS Q-Fan info (Frontend)

With the CPU Q-Fan Control option set to Enabled, a host of options display for configuring the operation of the fan attached to the CPU Fan header. The CPU Q-Fan Mode option controls whether the attached fan is a 3 or 4 pin fan, with the DC setting used for 3-pin fans and the PWM setting used for the 4-pin models. The CPU Fan Ratio option configures the speed of the fan when the CPU temperature is below the defined temperature threshold, with both manual and automated settings available. The CPU Target Temperature controls the CPU threshold temperature, below which the defined CPU Fan Ratio setting takes effect. If the CPU temperature exceeds the CPU Target Temperature setting, the CPU fan is run at full speed.

DCL notes:
Changed "Fan ratio" from 'auto' to 60% (the lowest setting) and fan noise dropped significantly after reboot. :)
