220T case, RGB fans & commander pro

[ShyyFaun]

Right, I have scoured the internet; watched videos, ready forum posts, spoken to people in fb groups, the lot! And nowhere can I find an answer to this and it’s so frustrating that it made me cry last night. 
 

A year ago I bought the 220t RGB airflow case. It had 3 RGB fans already in the front plugged into a lighting node. So I put the rest of my pc parts in the case and been working fine. However the fans are so loud and my previous case had sliders to adjust the fan speed so it was quieter. I wanted to adjust the fan speed and read online you need a commander pro for it. So I saved up for one. 
Also upgraded my psu so I got a commander pro recently and installed it all again. Everywhere online said you don’t need a lighting node if you have the commander pro as it does both for you.

 

However, upon turning my pc on after finishing putting it all together I open my iCUE and the fan speed says 0 even though the fans are running as they always have been but also the RGB lights in the fans weren’t on. And even though I tried to turn them on in the iCUE nothing happened. 

Questions:

Have I plugged it in wrong? If so how can the fans be running at all? 
Do I need the lighting node and the commander pro? If I do why do people online say you don’t?

FYI: 

I have NO RGB light strips. Just the RGB fans that came already in my case. I keep seeing videos on YouTube explaining this situation but with RGB strips and extra fans but that isn’t my situation and doesn’t help. 
 

Please please please can someone help?

What are the fan power headers connected to? And is the RGB still connected to the Lighting Node Core that came with the case? You would need to connect the fans to the PWM fan headers on the Commander Pro in order to control the fan speed. Before you do so, go to the settings for the Commander Pro and set the headers that you are going to use to 3-pin.

To control the RGB with the Commander Pro, you'd need to add an RGB Fan LED Hub. This is the dumb device that distributes power and signal to the fans. The Lighting Node Core, that you have, is essentially a Fan Hub + a single channel from a CP in one device.

Thank you for your reply @DevBiker

So all I did was unplug the fans from the lighting node that came with the case and plugged them into the slots on the commander pro that are labelled fans 1-6 (I only used the first 3 slots). 
Then the commander pro is plugged into my motherboard. 
 

So I need to use the lighting node and the commander pro at the same time? Why does it say online that the commander pro does fan speed and RGB? Im so confused

The Commander Pro does do RGB. It has 2 3-pin RGB ports. For it to provide RGB fans, one of these ports needs to be connected to an RGB Fan LED Hub (https://www.corsair.com/us/en/Categories/Products/Custom-Cooling/Accessories/CORSAIR-RGB-Fan-LED-Hub/p/CO-8950020). Without a Fan Hub, you will still need to use the Lighting Node Core for RGB. Add the fan hub, you can get rid of the LNC.

Now ... if you plugged the RGB headers into the PWM headers on the Commander Pro somehow ... well, I'm not entirely certain exactly what it'd do but that won't work. But I don't think it'd complete the circuit so you should be OK.

Please take a look through the RGB FAQ that's linked in my signature. Much is explained there.
