Fan control on the ASUS ROG Crosshair VIII Dark Hero can be accessed in the BIOS or by using Fan Xpert4 in Windows.The curve with the maximum output will be the mixed curve output. Use case: In this scenario, I want my case fans to ramp up if the CPU hits 45 deg OR if the GPU hits 50 deg and above.

This new type of curve allows to combine two existing curves and outputs the maximum of the two.

The fan will spin at the set speed regardless of the graphics card's temperature. Manual settings allow you to set the speed (in%) according to your need.

You can choose three settings to control your fan speed: Auto, Manual, and Advanced.
