Smart Fan 6 BIOS UI
1 - Improve fan curve UI: We increase control points from 5 to 7 and larger fan speed graph for precise and easier fan curve control.
2 - Slope/Stair dual graph mode: Fan curve can be quickly switch with Slope and Stair modes for different user scenario. Slope is traditional and intuitive linear fan speed curve. With newly added Stair non-linear mode, fan keeps at same speed between specified temperature interval.
3 - Manual Input: For advanced users, we provide fan speed manual input for more precise control.
4 - EZ Tuning: Use can place 4 EZ Tuning points at rough temperature/fan speed, and Smart Fan 6 can quickly generate a fan curve.
5 - Fan curve profile: Fan curve profile can be saved in BIOS ROM, profile will be kept after updating BIOS.

RGB FUSION 2.0
