No, not all fans are running at 100% continuously.

You're experiencing high fan speeds despite stable temperatures. Check if your cooling solution is properly seated and consider adjusting BIOS settings or using a more efficient cooler. Also, ensure your motherboard and CPU are compatible with lower fan speeds.
You want to make sure the motherboard isn't managing the fans at all. It seems unusual if that's happening. Are the fans connected correctly—do you have a PWM or DC setup? Also, what type of fans are you using?
I don’t believe the motherboard recognizes the case fans since there’s another small board on the back handling fans and other components. Perhaps I should remove those and connect the case fans directly to the motherboard for better monitoring. PS. It seems the CPU fan isn’t the issue at all.
If they connect to the case’s small fan controller, those motherboard BIOS images won’t show any data since the motherboard isn’t sending signals to the fans. Typically these controllers have an input fan cable linking from the board to a specific MMO fan port, allowing the controller to adjust speed using a single PWM signal. This should function, but you can always connect the fans straight to the motherboard and use the settings you shared earlier. Make sure the case’s fan controller board is connected via a fan cable if that was the problem, then it should be resolved. If not, simply plug the fans directly into the motherboard.
Switch to PWM control for the chassis fan. Set manual parameters to minimize noise up to 60°C. Apply changes immediately for quieter operation. Adjust the fan curve to suit your needs. If issues persist, verify the connection—sometimes the chassis fan is linked to the AIO/pump headers or monitors BIOS settings for temperature ranges. The motherboard likely displays a monitor page with fan speeds and other metrics. For external cases, use a low-noise adapter cable to reduce speed via a percentage setting. If the cable is installed, it may override the motherboard's control signals.
