Bios 3.25 fan issues Nova x870e Motherboard

   Hi,

After I updated to the new 3.25 bios, my fan settings does not seem to work correctly.

Before I could set it to auto and it found my fans and i could change the fan settings. 

Now it need to be set on CPU monitoring, and DC to work at all. But the FanTuning does not work either. Cant detect it, or do anything with my fans. 

Under FanTuning, one of the fans where starting stoping, and rest where just the same.

If they are put to auto, idle in windows sounds like a jet engine starting up.

Im not sure if im doing something wrong here, but its been working with no issues before.  

If there is a work around, I would love some help here. Getting pretty enoying listening to it.

	From the looks of it now. Its the auto mode that does not work out of the box. I did cycle through dc and pwm. Then put it to auto, then it seems to semi work. Its pretty quiet, and I sat a custom curve that it seems to override. Changing the profiles does not get detected in bios. Lets say I put it to full speed, nothing happen. I also notice that it overrides the settings and the curve i do in winodws. Now one of my fans are still starting and stoping in windows. So there is something funky going on after the bios update

	Did you "Load UEFI defaults" (exit menu) after the BIOS update ?
