" rel="nofollow - 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. |

A-Tuning alters the same values the UEFI does. If it isn't working try setting your fans to DC mode in the UEFI then check A-Tuning again. Not all fans are PWM compatible. -------------

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. |

I think at this point, I am going to uninstall A-Tuning and set the fan profiles in the BIOS and test to see that those are being followed. 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. |

Do you use AIDA64 for monitoring? I had the same behaviour as you, and disabling monitoring on AIDA solve the problem for me. Anyway, UEFI fan curves work very well. I suggest to use only UEFI for controlling fans, and the Windows utility only when you have to change fan speeds for some special use case.

I am using HWMonitor (standard version, not the PRO version) to monitor the fan speeds. The standard version of HWMonitor doesn't have the capability to change fan speeds. |

Yes I know. When I asked for AIDA64 was because for some reason, which I don't know, at some point the monitoring from AIDA messes up Asrock Fantastic Tuning monitoring, so you see that weird behaviour with fans, and the only solution is a PC restart. HWInfo64 is more reliable in my testings for sensor monitoring tough. Anyway, in your case, I suggest to configure fan curves on UEFI because in all my testing it worked very well. Cheers, |
