Notice:

• Before setting item's value, please first use ADL2_Overdrive_Caps ADL call to check its capability. Only the visible item could be set.
• The latest driver introduced Fan Curve feature and when it is available the legacy Fan controls will disabled.
• When setting FAN Curve, please follow below rules:
• OD8_FAN_CURVE_TEMPERATURE_n-1 <= OD8_FAN_CURVE_TEMPERATURE_n <= OD8_FAN_CURVE_TEMPERATURE_n+1
• OD8_FAN_CURVE_SPEED_n-1 <= OD8_FAN_CURVE_SPEED_n <= OD8_FAN_CURVE_SPEED_n+1
