Just finished my pc with 3 noctua nf-a14 ippc fans for case cooling. Noticed they were extremely loud and went to quiet them in bios. I tried using manual mode, but for some reason, the min. cycle limit was acting weird on two of the three fans. On Chasis Fan 2, I can set all the cycles to 5%, but on the other fans, I can only set it to 20%. Also in AI Suite, Fan Xpert 3 only show Chasis Fan 2A and the CPU fan are running/customizable. Do I have a defective motherboard or fan?
