No RBG output using ML PRO RBG and Lightin Node Pro

Hi,

 

I have recently built my first system. all is working well apart from two fans which are not giving me any rgb output whatsoever.

 

I have a 140mm ML PRO RGB fan at the top, and a 120mm ML fan at the rear acting as exhaust fans, as follows: https://imgur.com/goYYze5

 

they are working fine (as in rotating), connected to power via pwm headers, and the fan speed modulates fine using my motherboard software: https://imgur.com/60xsahV

 

they are connected to a Corsair RGB hub, in slots 1 and 2, and the RGB hub is connected to the Lighting node PRO. https://imgur.com/Wd6k4M0

 

the RGB and Lighting node are connected to a 3 socket sata connection, and the Lighting node is in a usb2.0 header at the base of the motherboard.

 

I know the Lighting node is recognised, as it is showing on iCue when booted: https://imgur.com/8O2zWo1

 

currently i dont know what else to try. i have tried using LED2 on the node, and swapping the fans around, but i dont want to break anything.

 

is there anything that may be causing my problems? what else can i do to troubleshoot? is this a manufacturing or installation error (and if instalation how can i rectify this)?

 

my completed system otherwise: https://imgur.com/enpcMXR

 

many thanks :)

i'll try and use the other fan that came with my 2x140 pack and see if i get any difference now that i know the cables are connected correctly and see if i get any rbg output. if that works i only have one 120 fan to replace, that should be covered by my 'build insurance''.

 

thanks for your help!

That cable is wrong. I can tell you that with 100% certainty.

The "bottom" connector in the photo has Pin 1 connected - it shouldn't be. It should be Pin 2.

Now ... if you want, I can walk you through removing the pin and putting it in the correct slot (pin 2).

This is how it should be. Note that pin 1 (with the triangle) is empty on both sides:

you have been incredibly helpful. I will first contact the retailer: if this is a defect, they will likely straight replace, saving me replacing pins/ helping me if the LEDs have been fried by too high a voltage. however, i will come back to this thread if i have any issues with warranties. thank you.

Let us know how it goes. And ... moving that pin is incredibly easy and safe. I do it quite frequently. All you need is a pin or super-small screw driver.

Sorry I didn't get back sooner.

To remove the pin ... see the silver on the "bottom" side of the connector, where the pin is? Push that in a bit. It's actually the latch that keeps the connector in place. You may need to do it a couple of times to get it to release but once it releases, you'll be able to pull the pin right out.

Once you have it out, you'll need to bend the latch back into place. A small screwdriver is helpful here. Just bend it "up" a bit so it'll latch. Then go ahead and slide it into place with the latch side towards that hole. It'll snap when you put it in about halfway ... that's good ... then just slide it in all the way until you hear/feel a click.
