QFan Tuning reset

NicMic

Hello,
After I updated the BIOS to the latest version on my M7H, I ran the QFan tuning.
Somehow, it has decided that one of my (PWM) fans has a min. duty cycle of 100.
So now I can no longer use manual control on this fan. I had to switch to the preset "silent" profile.
How can I "reset" the Qfan tuning ?

Bumping this in hopes that somebody has an answer. I ran into this on my Maximus VII GENE, and it drove me nuts - CPU fan minimum duty cycle got stuck at 100% with no way to set it back down to something sane. I even tried clearing CMOS, and it still wouldn't reset the Qfan tuning. Eventually I had to get another fan and re-run the tuning process to fix itself, which is a pretty terrible solution to something that really shouldn't be a problem.

I had this same issue. What I did as a workaround is reflash the BIOS and not run QFan tuning. I set each fan to PWM (since that's what is connected), and customized each setting to manual and it works fine. The only slight issue is that fan #4 doesn't spin at all until cpu reaches a certain temp but that is fine.

Let us know what you come up with. Hope this helps.
