I'm trying to use the ADL API to control fan speed on my R9 380X, specifically using the ADL2_OverdriveN_FanControl_Set command, but I just can't get it to work. I've tried using the sample program in the OverdriveN folder, as well as using my own code (see below), but no luck. Am I doing something wrong? Are there issues with FanControl_Set command? Any help would be appreciated.
// get the current settings
if (ADL_OK != ADL2_OverdriveN_FanControl_Get(context, adapterIndex, &odNFanControl))
// make our change
odNFanControl.iMode = ADLODNControlType::ODNControlType_Manual;
odNFanControl.iTargetFanSpeed = _speed;
// write back
if (ADL_OK != ADL2_OverdriveN_FanControl_Set(context, adapterIndex, &odNFanControl))
