Case fans controllable through AIO cooling in iCue, AIO fans uncontrollable

[somna]

Hi. I've changed around my fan setup a bit, and now I have 6 case fans plugged into a Commander Core, and then I have my 3 AIO fans + an extra 7th (rear) case fan plugged into the built-in Lighting Node Core and separate fan control device that come preinstalled in my 5000x case. Before I changed things around, I'm pretty sure the AIO fans were controllable through the AIO settings as expected.

Also worth noting: I only have 3 devices that show up in iCUE: H150I ELITE LCD XT, LIGHTING NODE CORE, and VENGEANCE RGB DDR5

Now, my AIO (+ 7th fan) RGB is controlled through the Lighting Node Core tab in iCUE

My AIO (+ 7th fan) fan speed is uncontrollable anywhere I can see in iCUE, so I have to use a 3rd party program (FanControl). FanControl recognizes all 4 fans as one fan (Fan #2)

My 6 case fans RGB are controllable under my AIO in iCUE, in the Lighting Setup tab

My 6 case fans speed is controllable under my AIO in iCUE, under the Cooling tab

 

As you can imagine, this is annoying. How do I get everything to work? How can I tell iCUE that the Commander Core is my 6 case fans, which should be controllable in iCUE, and the Lighting Node Core + other built-in case fan control device are my AIO fans (+ 7th case fan) and should be controllable under my AIO? I don't mind if that 7th case fan ends up linked to the AIO and I have to treat it as a 4th AIO fan. That's fine, as long as everything else is properly listed and controllable.

Picture 1: These are my 6 case fans. They show up under my AIO.

Picture 2: These are my 3 AIO fans (1-3) plus my 7th case fan (4). They are controllable under Lighting Node Core, NOT under my AIO.

so, your case fans are plugged into the AIO commander core, and the AIO fans are plugged to the LNcore.. what you describe is normal.

If you want the AIO fans to be controlled under the AIO tab, you have to connect them to the AIO commander core obviously. from the factory they should be connected to RGB and PWM fan ports 1 to 3 in the commander core.

The fan control device in the 5000x is not exactly a fan control device. it's a simple PWM repeater, or hub. All the fans plugged to it will be running as one. If you can control it via Fancontrol, this repeater must be connected to one of the motherboard fan headers. If you want iCUE to control it, you'll have to plug the PWM input of the PWM hub on one of the PWM channels on the AIO commander core

 

I'll give you an example of what you can do if you want all the fans controlled by the AIO in iCUE :

-AIO fans, connected as normal to ports 1, 2 and 3 (RGB, and PWM)

-7th case fan (rear?) connected to the AIO on ports 4 (RGB and PWM)

-6 case fans motors connected to the 5000x PWM hub,

-5000x PWM hub connected to the AIO PWM port 5

-6 case fans RGB connected to the Lighting node core

 

In that setup :

-the AIO controls all the fan speeds (AIO on channels 1-3, rear fan on 4, case fans on 5).

-The AIO controls the RGB of the AIO and your rear fans (RGB channels 1-4)

-The lighting node core controls the RGB of the 6 case fans

 

It all works under iCUE like this.

Thanks so much for your detailed response. This is my first build and these RGB/fan controller things are proving to be the most confusing part of the PC. Knowing that the fan speed controller is actually just a repeater is very useful. I think I'll go with the solution you listed, but if I wanted to use the case fans separately (not under the AIO), would I want to buy a separate Commander Core XT?

Either way, thanks!

yes. but you may not need to. You rarely need independent fan control for speed. Maybe you can get another repeater if you want to separate the front intake to the side intake for example, and connect that repeater to the free socket in the AIO.

It's usually best to keep it simple 😛 but you can add a controller and have them in separate sections of course.
