   From the GUI seems to work correctly.

Also I don't understand why if I select SILENT mode, it goes like crazy at maximum speed.

	Hello, I have an ASRock B450M with a Ryzen 3600 and I want to replace SpeedFan controls with BIOS settings. I want to set the fan speed at lowest level until temperature reaches 80 degrees. I have a medical ear problem and I cannot tolerate the fan noise. I set these options (sorry I cannot embed the photos even if I read the tutorial): https://imgur.com/a/37NuIZt https://imgur.com/a/mFB7pqz But it seems that even if the temperature is at 75 degrees (so lower than 80), the fan is at maximum speed (~1800 RPM). And I don't understand why, because until 80 degrees the fan should work at 1% based on my settings. Maybe I don't understand what "fan duty" means? How should I set these options properly? Thank you
