Wow! That is a LOT of Aquacomputer hardware! I can't tell if your screen shot is showing everything but if it is I see 4 x FW-Nano, 6 x FW-360, and 1 x FW-USB (I think). Then an Octo and 2 x Aquaero. I have to wonder - how many fans and LEDs are in this rig?
In contrast to all other products, you have to use the checkboxes shown on the RGB controller definition (where you define the effects) in which profile the current controller should be active.
I.e. you can chose to have any combination of controllers active or deactive in any of the profiles, which gives you an amazing flexibility.
Let us know if you have problems figuring this out, and I'll provide screenshots. Or you look into the manual![]()

Look at that screenshot of my Farbwerk 360 setup. See the colored boxes on each line (I've marked them)? They show which profile the respective controller is assigned to:
[attach]8779[/attach]
That means, if you activate profile 1 (blue), only controller 5 (the bottom one) and Controller 4 (the top one) are active.
In profile 2 (red) controller 3 and 4 are active and with profile 3 (green) controller 13 and 4 are active. With profile 4, ONLY controller 4 is active.
You can set which profile a controller is using with these checkbuttons:
[attach]8780[/attach]
Hope that helps!
There's literally no power draw from the USB headersonly enough to power the board logic. all the heavy current draw is on the molex or SATA cables.
Also, using unshielded cables can lead to some.. interesting results, but these are not really high speed devices so i guess it works?
if the FW360 pull too much current on RGB, they will shutdown and latch the affected port(s) off until the next reboot WAY before cable heating becomes an issue. Aquasuite displays a warning message if it happens.
But again, there's no significant power draw on the USB headers but only on the SATA and molex 5V, if you get too enthusiast with white lighting.
As for the sata switch, i don't see the point either. Given how many devices you have connected, does it reduce the idle CPU usage while Aquasuite runs?

As long as the Nanos are connected to the NZXT hubs they will draw no power from the motherboard header. And USB2 supports over a hundred devices per port, so 20 isn't that much, as long as you have enough bandwidth, but these controllers don't take much.
Now, if you switch the SATA power to the hubs, that may be an issue'
It's possible with such a busy build that they were suffering from crosstalk from other cables. Maybe the shielding did more good than the thicker gauge actually.
I only have one Nano that i use externally, so i have no idea what having its coiled cable in the case would do
Also, there's an option in aquasuite to increase the Nanos power draw to 2A, to allow for brighter lighting. If they are indeed on the powered hubs, you can enable that to get some extra brightness on the QLs![]()

In theory, with USB hubs, you should be able to connect an almost unlimited amount of devices to a PC. But the more hubs you stack, the more unstable (and slower) the USB devices will become.
To get an idea how much your USB stack is already cascaded, you could look at the Device Manager and switch to the connection view. Because many devices already come with internal hubs - and the Mainboard itself is also using logical hubs to multiply the number of USB connections.
Since I've neglected to say it before: Your build is truly amazing. I'm humbled by what you did there.

for signal integrity or crosstalk, that's oscilloscope territory'
We only care if communication is reliable. I don't know what hub is that amazon one, too many references.
The 127 devices theoretical limit is hard to reachbut to have the most reliable connexions possible you want to try to avoid daisychaining hubs in a long line.
I believe you already avoided that by using one hub to which all the others connect, and then all your controllers were in those secondary hubs (basically, the shoter the USB chain is, the better signal integrity will be).
I remember when USB came out, they actually demonstrated a laptop with a ridiculous amount of USB devices connected to hubs everywhere into a single connexion and it worked. but that was a laptop
In a computer case with high power components, bare PCBs everywhere with absolutely no shielding, and DC to DC converters radiating EMI all over the place, it's no wonder it's hard to get that many devices working.
That's why i try to keep the build as simple as possible(btw, no offense taken i was only pointing at the theoretical limit of USB, no worries!)
One thing i don't think we mentionned.. have you thought about adding internal headers through a PCIE card? that would allow you to split the controllers into shorter USB chains and have a more direct connexion to the motherboard.
And i'd love to see photos of the build's wiring too ! talk of some extreme stuff!

it shows as out of stock here.
There's also dual USB3 cards i've seen, and you can add a USB3 to USB2 header cable to adapt. both styles would work (and they were black PCBs :p)
