Currently trying to throttle down a noisy fan on the rig, and unfortunately my GA-970A-D3 does not come with a fancy UEFI like all these new models now. So apparently I cannot adjust fan speed through the bios according to the manual, and easy tune doesn't seem to be responding to my changes. I also had some issues with speedfan, not being able to control anything. Some 120mm's are connect to a 3 pin and others a four pin header, but neither seem to be responding. In fact the only fan that was affected was the CPU fan when I fiddled on the smart tab. Am I missing something in the bios or software? Im a bit stumped. All help is appreciated.
