SFF build, want to use the header with Fan Control app to control 120mm GPU fans to cool GPU which has the shroud and fans removed. BIOS shows CHA-FN1 N/A though there is an 80mm chassis fan plugged in and running on it now, it does not show up in HWmonitor as well.

I have the two 120mm fans plugged into the CPU header on the MB as available due to
the AIO taking care of the CPU cooling and fans on the 280mm radiator.

Another issue is Fan Control does not see any MB fans or headers, sensors, etc....though those show up on HWmonitor.

I want to either run the 120mm GPU cooling fans from the GPU headers or from Fan Control from the MB.

I can use a fan hub to control them with the cables I bought to plug the fans into the GPU but go to the hub instead of the fans then the fans from the hub but limited space, air flow issues, keeping it less cluttered, etc....

Any help would be greatly appreciated.

Thanks
Rick
