Is there a software solution? Or is the motherboard dying? Any advice would be appreciated.Fan Xpert 4 in AI Suite 3 is used to control all the fans that connect to the motherboard, user can adjust rotating speed of fans to customize the need. I've seen any number of forum posts about similar problems, but no solutions. They're PWM fans, and correctly set that way in the BIOS.ĪSUS tech support says I should send them the motherboard for servicing, but that's a last resort. The motherboard is an ASUS ROG Strix Z390-E Gaming board, the fans it doesn't like are the ones that came with the Fractal Design Define R6 case (Dynamic X2 GP-14 fans). Both BIOS and Fan Xpert recognize and control the CPU fan with no problems.
With AI Suite 3 uninstalled, the fans work as they should, but if I reinstall it they run at 100% all the time. In the BIOS settings, the QFan Control recognizes all the fans and sets their speeds correctly. I've updated all the drivers and the BIOS, and still have this problem. It doesn't seem to believe they exist (they're just a blank when I select them in the program), and runs them at 100% speed at all times.
ASUS Fan Xpert 4 (part of their AI Suite 3) has stopped correctly recognizing the chassis fans. A computer I built has developed an odd problem with its chassis fans, which I'm hoping is a software issue rather than hardware.
