I have 5 Noctua NF-A14's to replace and add to the case. I guess I could order a usb hub, but to get the potential of true 3.0 would it need to wire off some sort of card since the case ports use my one 3.0 mobo header?

Does this mean that if I plug the D-14 into cpu_fan and the splitter/case fans into cpu_opt all parameters set for cpu_fan will be the same on cpu_opt or can there be a set of parameters for each header?
Would you try these fans with LNA adapters on first or see how loud it is without?
Also, am I safe on power requirements for these fans? I don't recall seeing a power rating on the splitter like I have on fan controllers.
Thanks in advance.
I have no problems with supplied USB headers. That's using webcam, mouse, keyboard, HTPC remote, 3TB HDD, as well as USB sticks. Maybe someone with more USB experience will jump in here.
Yes, on all motherboards I know of both the CPU fan and CPU opt use same PWM signal.
I would set up the system with all fans speed controlled by motherboard. Possibly GPU too if it's high heat / power consumption, but usually when GPU is working the CPU is too.
As Genesis said, fans don't have to be variable speed based on system load / heat. To me it's only common sense to do it. Notebook / laptops do, CPU coolers do, GPUs do, CLCs do, custom loops do, cars, truck, motercycles, etc. all do too. So why not the case fans too?
