"Won't let you change..."  Does that mean you change the lighting in CUE and nothing happens or you are unable to change the lighting because there is no way to interact with the fans in CUE?

Odd that you cannot control the speed either.  PWM speed control is completely separate to the RGB lighting and they work independently of each other.  In this case they are on two different controllers.  


Speed control should be through the "cooling" tab on the Commander Pro and PWM wires from the QL should be connected there.  The Lighting Node Core is the RGB controller. 

 

In "Lighting Setup" make sure you have it set to "QL fans x 6".  However, you may need to explain how the SP-Elite fans fit in and where they are connected.  Combining QL (34 LEDs) and SP-Elite/ML-Elite 8 LED fans on the same controller is going to be problematic aside from static colors or stationary effects.  In order to properly set the number of LEDs, we need to know exactly how many QL and SP-Elite you have and the order they are connected on Lighting Node Core.

I created another account so i can message but i have 2 lightning node core connected to a Commander pro which has the 3 QL and 3 SP fans connected and 3 ML fans connected to commander core with my h150i elite capellix

I don't think it is related, but you can drop one of the Lighting Node Cores and move the SP-Elite onto the RGB port side of the Commander Core.  SP-Elite and ML-Elite are identical for RGB purposes and share the "8 LED fan series" designation.  I can't think of any reason to use the extra LNCore.  If needed, you still can divide the fans on the Com Core into 2 groups with separate effects for ML-E vs SP-E.  Commander Core uses independent RGB headers and auto-detects, so no real set-up needed as long as you start from a full power off state.  LN Core devices are serial.  Make sure fans are 1-2-3.. sequential.  

 

Are you unable to change fan speed on all devices (Com Pro and Com Core) and also unable to change lighting on all three RGB controllers (LN Core x 2 + Com Core)?  That would suggest something is interfering rather than a singular device setup issue.  Do you see strange fan speeds or UI elements disappearing?  Make sure you are not running other programs that are attempting to access the Corsair hardware at the same time as CUE.  HWiNFO and AIDA are common obstacles on the monitoring and fan speed, while some MB RGB programs try to take control of everything if allowed.  

 

Aside from that, you might need to show us the cooling and Lighting effect tabs.  I am having a hard time finding a clear thread to pull on here.

The Commander Pro is an older controller and does not work the same way as the Commander Core. Do NOT rely on the presets for fan control. “Quiet” on the Commander Pro will not produce the same result as the Com Core that uses the AIO coolant temperature as the control variable. In the cooling tab for the Commander Pro hit + to create a custom cooling curve. A graph will appear below. Select one of the shape tools in the lower corner but you must change the sensor to “H1xx Temp” (AIO coolant temperature) for the curve to make sense. Change each fan above to that setting. Change Commander Pro settings to “4 pin” for each header in use.  
 

There is no device to device control in CUE. The Commander Pro cannot control any lighting because it has no RGB lighting hubs connected to its LED ports. You must control lighting through the Lighting Node Core device and lighting effects tab.

do i even need to use the commander pro

You do not need the Commander Pro except as a source of fan speed control for any fans not on the Commander Core.  However, there is another way and one I prefer when using larger numbers of fans in water cooled systems.  You can use a PWM repeater to serve as a powered splitter for 4-10 fans, depending on the model you choose.  This uses 1 PWM header from the Commander Core and all fans on the PWM hub will run the same speed.  This is usually not an issue on all these  "bank of 3"  cases where you don't need individual fan control.   If you have a 5000 or 7000 series case you may have one in the box already.  Otherwise they are cheap (less than $20 USD) and much smaller than a Commander.  In addition to space and cost savings, the advantage is it can use the same native coolant temp sensor on the Commander Core so all fans can be controlled from one device location in CUE.

 

The counterpoint to this is if you don't have enough USB 2 ports and do use the Commander Pro as a passthrough, then PWM hub + USB hub may not be better than a Commander Pro.  AMD owners need to be careful here as the Commander Pro is passive USB splitter whereas a powered USB hub is essential for those having voltage drop connection issues on the motherboard.  There is no device to device control with CUE, so connecting the Lighting Node Cores to the Commander Pro does not provide a benefit aside from a place to connect.  USB 2 connection is required to be able to manage the lighting.  

 

In this instance, you are likely using 2 USB ports on the MB -- 1 for the Commander Core (required) and 1 for the Commander Pro which is hosting the two LNCores.  However, since you only need 1 LNCore for your QL or ML-Elite (with all others on the Commander Core), then you still only need 2 USB connections.  1 for Commander Core, 1 for the LNCore.  This means you should be able to drop the Commander Pro and use a PWM hub if you want to.

i have the 5000x case so i just plugged the repeater back in and i had plugged it into the commander core and had put the lightning node into the mother board and the ql fans and the sp fans are stuck at green still while the other fans on my h150i that are plugged directly into the commander core are working fine as before, did i do everything correct or did i miss plug something? i dont know what is happening.

Do you have QL and SP-Elite mixed together on the Lighting Node Core?  It would be better to move the SP-Elite to the Commander Core for RGB control.  Those are a match to the ML-Elite from the AIO kit.  The QL are too weird with a double sided 34 LEDs and need their own controller.

 

On the Lighting Node Core, you must connect the fans sequentially starting from RGB port 1.

i wont have room for for the for the repeater if i plug in the sp fans in the commander core directly what do i do?

So the sp fans and ml fans are now good and the lighting I can change but the ql fans I can’t change the lighting and this is how I have everything hooked up so first I have the 3 ml fans everything is hooked up directly into the commander core and the so fans I have the rgb Port plugged into the commander core and the other cords put into the repeater and those are working and the ql fans I have hooked up to the lighting node and the other cords into the repeater and the ql fans are not showing any leds at all

EVERYTHING WORKS!!!! Thank you so much for using your time to help me the reason why the ql fans didnt work is becuase i didnt put them in the rgb port 1 2 and 3, so everything works now thanks!!!

If it's still an issue, get 1 PWM splitter (standard cheap type) and pair of any of the side or front SP/ML-Elite fans.  That's not a problem for the controller and then leaves 1 header free for the repeater.  The alternative is to move one of the PWM connectors from any SP/ML-elite to the repeater as well.  However, since they have different locations and specs, a PWM splitter is better.
