I'm confused about this discussion. I just finished building my new system with this fantastic motherboard, I did randomly discovered the automatic fan tuning feature in the BIOS and tried it, and now when in Windows I see that my 2 case fans and CPU fan are adjusting their speed based on how hard I am working the computer. What am I missing here?

I did notice this as well, but I think they simply force tctl now as the only option. If you notice the fan tuning page, you will see on the CPU there is nothing selected for the options that are available, implying that it is locked to the invisible tctl. :-)

HWiNFO shows temps are reported the same with the mystery new setting, as they were set to tctl on mine.

Yes, I think the Tctrl vs Tdie offset is defined by AMD.

I test many B450 Boards and test OC too, and yes with Bios update 3.10 the Version Tctrl is deleted from bios, you can only Monitor MB or CPU. And the Standarts like Custom Silent and ??I ask Asrock a lot and the german support test for me too on a B450 Pro 4 and it works, but i say Asrock miss a Code in the System for check the Fan Control. Only good Fans atm work on the Board is Be Quiet or Noctua Fans, is horrible Design from Asrock. Tctrl can only to be activated via windows, and that over the Asrock program for the Fan Control.

I wish Asrock would work better with the Community on the Problem and would solve it because everyone eventually also paid money to get a reasonably clean system.
