Does the Debug File capture the situation of resetting and what situation represent the screenshots ?
I can't find a possibility in HWiNFO that it would set Auto mode on its own when the Custom Auto mode is active.
Are you sure you haven't clicked anything in the fan control window ?
In this dump I only see HWiNFO setting fan speed to 4500 RPM and nothing else.
So if the system set the fan back to system control, then it's not HWiNFO fault. Might be another application or firmware/BIOS.
No, I'm sorry but I have no idea.
I haven't enabled the respin for these models, because I thought it's not needed.
Since I have recently received more reports of similar situations (system taking fan control back), I'll enable this feature in the next build.
Was that an application (HWiNFO) or system crash ?
