X570 Crosshair VIII Hero (wifi): Fan curve not sticking

hwanzi
Level 7
This is my fan curve I set in my bios for my ALL my fans, but when I go into my computer it refuses to use my fan curve for some reason. The ONLY way I can get my fans to actually use my fan curve is to use a program and then manual set the fan curve again. I am on bios 4201 and have downgraded to 4006/3904 and this problem persists no matter what.


  • Basically what I would do is set my fan curve on each of the fans
  • Go to the profile page to save to my profile
  • Save and Quit

Below are pictures showing my CPU fans not going to 100% (1800 rpm) when temps go above 65 degrees, but when I manually set them in the program they will reach 100% (2200rpm). Does anyone know why?
