X370 Taichi Fan Behaviors

Hello,

I have a X370 Taichi mobo (BIOS ver. 3.00) with a Ryzen 7 1700 (non-overclocked) CPU with the stock Wraith cooler, and two sets of PWM case fans (each set with a Y-cable).

In the BIOS, I have all fans set to the setting above "standard" (without going into my BIOS, I believe the setting is called "performance"), and is set to "Monitor M/B".

In A-Tuning, which I have set to start at system start-up, I have defined fan profiles for all fans.

However, I'm noticing that the fans are not following my A-Tuning fan profiles.

Which takes precedence, the BIOS fan settings or the A-Tuning fan settings?

If the BIOS settings take precedence, how do I get the A-Tuning settings to take precedence?

Thanks.

Thanks.

If the profiles I am setting in A-Tuning are the same ones that are in the BIOS, then there is something else going wrong.

All fans ARE indeed changing their speeds in response to changing CPU temperatures.  The case fans are definitely 4-pin PWM fans.  Two fans are on one Y-cable, and the other two are on another Y-cable (connected to CHA_FAN1 and CHA_FAN3, respectively).

But the problem is that they are not following the profiles I am setting and seeing in A-Tuning.   They are following something else.

At one point, I opened A-Tuning and my CPU fan speed dropped to a very low speed, despite that fact that the CPU was at 100% (I'm running BOINC) and the CPU temps began rising dangerously.  It required a reboot to recover. I think the conflict is with A-Tuning.
