High-power radiator fans operating beyond recommended settings Biosystem curve not being observed
High-power radiator fans operating beyond recommended settings Biosystem curve not being observed
I just finished a fresh build with the 9800X3D, Asus B850F Gaming WIFI and Arctic Freezer III. The hardware integration was solid. I powered it on, set up Windows, and everything functions properly except for the radiator fans. I checked common troubleshooting steps—made sure the FAN cable connects to the CPU_FAN header on the motherboard. All fans are PWM units. In BIOS they’re using the default normal curve, but they’re spinning at 3000rpm instead. I downloaded fan controllers from various sites and even tried the ArmouryCrate, but it didn’t recognize any of them except my GPU. I also experimented with BIOS settings, attempting auto-select and manual curves, but nothing changed the setting. The fans remain stuck at 3000rpm. Any suggestions or assistance would be really helpful.
