Frizzo Posted July 19, 2021 Share Posted July 19, 2021 Hi. Sorry for my bad English. I've 3 RGB Fan: 2 LL140 and 1 LL120. The 2 LL140 works perfectly with the iCue software, but the LL120 does not light up (only spin). I've the node pro with the hub. If I put 1 (LL120) 2 (LL140) 3 (LL140) no fans turn on. If i put 1 (LL140) 2 (LL140) 3 (LL120) only the first 2 will light up. I've tried iCue software v.3 and v.4: same problem. I've also tried to connect only the LL120 to the hub, but it will not light up. I think the LL120 is not damaged, because If i connect it to a simple switch of my case ( see attached ) it will light up, but only static red.

c-attack Posted July 19, 2021 Share Posted July 19, 2021 There is a problem with the LL120. The RGB on most of these controllers is serial, so a bad LED or fan will affect anything further down the line. I don’t know what the specifications are for that switch, but I would not connect any more Corsair fans to it without being sure. Contact Corsair Support to see about a replacement for the LL120 or use any local replacement options available. Link to comment Share on other sites More sharing options...
DevBiker Posted July 19, 2021 Share Posted July 19, 2021 If that switch has 4 pins like the Corsair fans do, then it's going to be a 12V analog RGB controller. The Corsair fans are 5V digital. Pushing 12V into a 5V LED is a really excellent way to release the magick blue smoke. Link to comment Share on other sites More sharing options...
