SP RGB Fans - Unable to change Lighting


Recommended Posts

Recently got my prebuilt PC from Origin and have Corsair RGB SP Fans that remain rainbow color (6) that I am unable to update via iCUE software. Think I have the node pro or something that I use to change the color, but no luck on be fans

My LED strips and other Lighting work great!

Tried the following...

- on latest software/driver updated

- do not have MSI Center installed

- uninstalled services and repaired application

Can you be more specific about the fan name?  There are a half dozen fans with “SP” in the name and the differences are critical to question at hand.

The Elite series AIOs come with an OEM version of the ML-Elite (8 LED) fan.  Most newer cases will come with SP-Elite, another 8 LED case fan designed to compliments them.  They both are set as "8 LED fan series" in the Lighting Setup for your Commander Core controller that is required for the Elite AIO.  The Commander Core should auto-detect fan type.  The problem is builders can stick whatever they want in these cases, so we have no idea if you have the same gear as what was meant to go with these parts or something else.  

 

The Commander Core is different from a Lighting Node Pro or Lighting Node Core.  CUE should accurately list the controller name.  You can't change that.  The fans are trickier, especially if you have a Lighting Node Core or Pro that is a serial controller.  You must properly set the fan name in the Lighting Setup.

I have the Lighting Node Pro. Not sure what Commander is.

Under Lighting Setup, I did try SP RGB and 8-LED and selected 6 and the RGB Port fans under the channel still did not change still...

Something I am missing? Should I try to replug them in? Don't need to do anything on the Hardware Lighting right? Honestly I probably will unplug the RGB connector, if I can't change the color.

Hardware Lighting is how you set the active lighting effect when CUE is not running.  These are simplified effects that can be saved to the controller.  No need for that yet, but you can set something there to see if it changes.  If there is a bad fan or controller, it will show in both hardware mode and software mode.  If the problem is limited to when CUE is running, then it may be a set-up error or a software issue.  

 

The SP-RGB is the original 5v RGB fan from 5 years ago.  Hopefully that is not what they stuffed in your box as it is both discontinued and difficult.  It cannot be on the same circuit as other Corsair RGB fans.  That would knock out most of the fans.  

 

CUE allows you to lie to it.  So if I tell it I have "QL x 6" it will generate the 34 x 6 = 204 LEDs on that string.  That's a quick way to check to see if the fans are working, although I suspect you have 8 LED series fans.  Make sure you go to Lighting Effects and add something to group or go to "scenes" on the main page.  Scenes are a quick master override of all lighting groups.  This also is good way to check lighting functionality.  However, if you don't do Lighting Set-up and tell it something, it won't generate any LEDs for that device.

 

If you have an Elite AIO, you must have a Commander Core.  It is required to power the pump.  That device has 6 PWM headers and 6 RGB headers.  I am kind of surprised they did not use that to control the RGB fans.  It is the obvious tool and then you use the LN-Pro for things like RGB strips or accessories the Commander Core cannot do.  The Commander Core also has an auto detect protocol, so if anything is connected you can re-run the scan by going to the settings and force it to check the LEDs.

I did notice when looking in the case, the USB plug from the RGB/Fan hub is unplugged by the Power supply. Is that needed or information on where that would plug in?

The USB connection is how the device communicates with the software.  If it is unplugged, the device will not show in CUE and you will have no control.  Follow it back to the device (LN Core?) and see if fans are connected.  If yes, then the USB needs to be connected as well.  If no, then it does not.  Many of the cases come with a lighting controller like the LN Core or LN Pro, but if I were building it I would put them on Commander Core so there is not definite you need this.  Only if fans are connected.  USB 2 internal ports are usually located on the bottom edge of the motherboard.  Be careful, there are other ports that look similar.  The USB 2 internal has 9 pins in a 5x2 grid.

You definitely have fans on the Commander Core (larger controller) for PWM speed control and RGB. That controller should auto detect fan type and they should automatically appear in the Lighting Effects tab for the Commander Core. It should show the AIO pump face in CUE for its picture. 
 

The smaller one is a Lighting Node Pro and something is connected to channel 1. Follow that skinny wire from LED 1. If it goes to a small rectangular fan hub with 1-6 numbering, then fans are connected. You will need to know how many and what kind. The Lighting node pro does not use auto detect and must be manually set up. If you have LED strips in the case, they are likely connected here (no hub required) and then you tell it LED strips and how many in lighting setup.

LED 1 is the LED strips that do work. And those 1-6 are fans are connected and working. I just can’t control the RGB on the 6 fans at all, which is the issue here.

The LED strips are really the only thing, plus the motherboard, that works when changing the RGB colors in icue.

when you say lighting effects tab, are you referring to iCUE under the node pro device? Here is a picture. I had to do the lighting setup manually. Node pro was detected but still unable to change colors in the fans. Also tried all the different “fan types” too in drop down and no luck.

maybe it’s not detecting because the USB cable is not attached?

Ok, I think we are down to the root of the problem. Your strips are on Lighting Node Pro, channel 1.  There is nothing on channel 2 and I can see the empty slot in the picture above. There are definitely 6 fans on the Commander Core. It’s your Commander Core that is not detected. Find the usb 2 from that larger controller and follow it. It needs a motherboard connection as well. 
 

Go to Commander Core “lighting setup”. It should auto-detect, but if not manually set it to “8 led series” x 6. Then go to “lighting effects” for the Commander Core. Hit + to add. Now you should be in business.

Thanks! I will try this. guessing I should plug it into USB 2.0 on MSI motherboard with machine powered off? Do I need to re run anything on boot up?
