6 QL120 Fans, only 1 and a half light up

[wutqq]

Hi,

I just built a new computer and am new to RGB. I have 6 QL120 fans that are all spinning but the lighting is only working on a single fan and the center of the second fan.

 

- 6 QL120 Fans are plugged into the Lighting Node Core and Commander Pro

- Lighting Node Core is plugged into SATA power and into the USB on Commander Pro

- Commander Pro is plugged into SATA power and internal USB header

 

I can only see the lighting on the 1st fan and 2nd fan (only inner ring). All 6 fans are spinning and can be controlled via iCue. All 6 fans show up on iCue Lighting Setup/Channel.

 

*Update*: I have now tried a second Lighting Node Core with no change. I have also tried plugging the Lighting Node Core directly into the motherboard internal usb header with no change. I have also tried having the Commander Pro and Node Core powered by separate SATA power.

 

Unless I am missing something obvious, I either received 4 1/2 dead rgb fans out of 6??? These were purchased brand new sealed.

 

*Update #2*: Ok, I now tried switching RGB connectors on the Lighting Node Core. I took the #1 and switched it with #4. Now the #4 fan (plugged into the #1 position of the Node Core) is fully RGB, but the previous #1 fan (now plugged into the #4 position of the Node Core) has no RGB.

 

*Update #3*: Ok, so I had a hunch the #2 position fan could have an issue and causing each fan after that to also have an issue. I removed the RGB plug of the #2 position fan and now every fan has RGB except the unplugged one. I believe I may have solved the issue, just 1 bum fan.

 

*Final Update*: Yes, it was the #2 position fan. It looks like it needs to be RMA'd and was causing all other fans after it to not work.

Well ... looks like you got it.

And yes, these things are typically one bad fan. The other option is mis-configuring the channel in iCUE.
