Correct you set one and the other follows basically. I'm looking at 3 amps I believe. I think my fan hub is 4 3 pins and 3 4pins. I've got 11 noctua NF-A14 I dont intend to daisy chain them all because that would. Be alot of amps wats ect. So I'll do 2 on each of the fan hub that's 6, two are on my d15 so they are in the motherboard the rest I will spread around my mobo. How do you check what you hub can handle? Also where do you see the power draw in bios of each port?
