9 QL fans - how to -commander pro - commander core xt

Hello everyone! 

I came today with a simple question and asking for some enlightment. I have a commander pro  and a commander core xt.

Right now I have only 6 fans all connected to my comander core xt.

I want to add 3 more but I want to keep the synchronism between all the fans. (for rgb) 

 

So i wanted to ask what should I do, my guess is to connect the commander core usb to the commander pro and the 3 extra fans into de commander pro and the rbg cables  of those 3 fans to a lightning core pro.

 

do you think this configuration will allow me to keep the "order" with the fans (for purely rbg modes purpose).

Thanks for your time.

Yep that sounds correct, I have 10 fans, 6 QL's on CCore thats ships with the Elite Cappelix and 3 LL's on CPro with LNP, and 1 QL on Lighting Node Core. USB for the CCore and the LNP is plugged into the CPro's USB ports. 1 more LNC with USB directly attached to MOBO.

There is no continuity between controllers.  The fans on RGB controller 1 do not sequence or share the same instance of an effect with the fans on controllers #2.  You can set the fans to do the same thing (synchronization), but it will be 1-6 on one controller and 1-3 on the other.  Presets do not continue to the next device, so the only other way to do this is by programing delays on one set and the other to create the appearance of sequential movement from one set of fans to the other.  

 

The Commander Pro USB passthrough is just that -- a passthrough.  It is not a device to device communication path.  If you already have it, it can be used for fan speed control, but if you don't have a RGB hub then you need a Lighting Node Core anyway and it's a bit wasteful on space and resources.  If you are on a recent AMD motherboard, this is likely a bad idea from the start and you will be better off with the powered USB hub and powered PWM repeated method.

Thanks a lot!! 😄 I'll try the config hope it works.

Oh I see... I have a commander pro a commander core and a  light node pro.. right now only using the commander core for my 6 QLfans. I want to add 3 more Im on intel 12th gen motherboard.. what do you recommend to do? 

 commander core usb and light node pro usb into commander pro? 

also can you edit that "delay" from icue? or it is a more complex thing to do .. thanks a lot for your time !!

The hardware you have should work.  Since it's Intel the passthrough from LNCore to C-Pro should work and I am assuming you have 2 USB 2.0 internal headers so it has value.  If you could find a RGB Lighting Hub, that would connect to the C-Pro RGB channel and replace the LNCore.  It is smaller and eliminates an extra device.  However, they seem to be in very short supply with Corsair de-listing them.  It should be a $10 USD part, but it's more like $20 on Ebay now.  Nice if you could get it, but not required for this to work.  Another option is get a powered PWM repeater and that replaces the C-Pro entirely, but since you already have it that may not be worth anything unless space is really tight.

 

Programming a wave to start on the 6 Com-XT fans then pick up on the LNCore 3 fans requires some experimentation.  There is a clear mathematical element to the functionality and it's all about the number of LEDs and their speed.  So for example if I set a wave up that has a tail of 32 LEDs (2 QL/LL fans) and set it for a speed of 16 LEDs/sec, it will take it 6 seconds to reach the "7th fan" and 1 more second for the tail to complete.  You would want the LNCore set of 3 to wait 6 seconds before initiating a copy of the original wave.  It takes 3 seconds to reach the end of group 2 and 4 sec for the tail to complete.  So to make the entire thing a seamless loop, the lighting time would be 10 seconds for both, with a 6 second delay before the second wave starts on controller #2.  Or at least in theory.  There usually are some corners to round and this was a simple example with a speed to match the fan LED count (1 fan per second).  You'll need to do more math when using odd speed or lengths, but the big take away is understand you can't set presets to both controllers and it runs 1-9.  If you set Pong on both controllers it will run 1-6 and 1-3 with two separate pong games.

Thanks a lot for yout time friend! I'll try it.

have a merry christmass!
