Hi just registered as found this forum when searching for my problem. I was given 2 sets of QL 120mm LED fans as a present last Christmas and recently they have all been doing strange things and sometimes all the fan LEDs would stop working. The actual fan still works as intended. Do not connect more than 10 UNI FANs (device up to 21W) to the controller (UNI HUB) when performing white static color. To connect more devices, please update to L-Connect 2 (reference to update guide) and use 2 or more controllers. Rule 1// The tubes of the radiator must avoid the tenon of the UNI FAN and be at the safe area, which is in grey in the image. Just wondering if anyone else has encountered this. I've searched for the issue and it does not appear anyone else has posted about this problem.

Please enter your motherboard BIOS and set the correspondent fan header at PWM mode. (Update your motherboard BIOS if necessary)Interestingly, with all 3 they seem to be fine, until all of a sudden this problem shows up when I turn the PC on. After running for some time, the bulb appears to "fix" itself. This continues for days to weeks until it progresses eventually to breaking entirely and just stays pink/whatever color minus green at all times. With the above wiring guide, you can see how to connect an H150i ELITE LCD XT AIO with 4x QL120 RGB fans. The diagram was designed around this example, but the principles can easily be used for other configurations, too. Here's a breakdown of what's going on. The manual specifies that the node core box requires one USB header on the motherboard as well as an additional SATA power connection, I like that the cables are built in to the core box and you can't bork it by removing the cable at both ends but as before I hate extra cables. All of the fans are connected to lighting node cores and controlled through icue. There are 6 fans on one LNC and 4 fans on another; they are definitely not overloaded and I have tested the ports they are plugged into. There really isn't anything unusual about my setup, I don't think. Everything else about the fans, including all of the other LEDs, appears to be functioning just fine.

Finally, the LCD kit is connected to the CPU_FAN port of the mainboard, and all controllers/repeaters are connected to the power supply via the SATA power cable.Speaking of moving air, the stat you want to keep your eyes out for is “CFM,” which stands for “cubic feet per minute.” The higher the number, the more air the fan can move, the better. That said, fans with the highest CFM also tend to be loudest. The 4x QL120 RGB fan (No.7) is connected to the Lighting Node Core and the PWM Repeater of the iCUE 5000x RGB case.
