Hi,
I installed a Fans 1-3 (3 front facing) and Fan 4 (rear exhaust) in my case. For purpose of this system, I will name my two other fans, Fans 5 and 6 (Top radiator out, push configuration). All 6 fans are Corsair LL 120 mm White. Fans 5 and 6's led connectors are connected to the H110i. It has no problem.
However, Fans 1-4 are connected to a Lightning Node Pro (as part of the 3 pack corsair white 120 mm LL fans) via the 6 way LED Hub (which connects Fan 1-4's led cable to input 1-4, connected in series to the Lighting Node Pro at input 1. The Lighting Node Pro is connected to my motherboard's USB.
I installed this tonight and immediately, I noticed both flickering and random light going on and off on Fans 1-4. If I set all Fans 1-4 to default rainbow wave, Fans 1-4 flicker like crazy. If I set instant lighting on all of iCue to "black", Fans 5 and 6 turn off completely. Corsair vengeance RGB turn off. But Fans 1-4 randomly light up parts of each fan for about a second, consistently. Fans 5 and 6 (because they are connected directly to my H110i) have no problem.
I took 4 pretty good videos that perfectly capture the problem, but this forum wouldn't let me upload them. Possibly too large size. I still think I described the problem properly.
I tried to comb through similar problems in this forum but didn't really find a good solution. Any help would be appreciated. Thanks!
