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.]]> Mon, 29 Nov 2021 02:48:23 +0000 https://forum.asrock.com/forum_posts.asp?TID=19877&PID=91121&title=asrock-b450m-bios-fan-speed#91121 https://forum.asrock.com/forum_posts.asp?TID=19877&PID=91120&title=asrock-b450m-bios-fan-speed#91120 Author: taw_moto

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):

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]]> Mon, 29 Nov 2021 02:00:54 +0000 https://forum.asrock.com/forum_posts.asp?TID=19877&PID=91120&title=asrock-b450m-bios-fan-speed#91120
