Problem with Corsair LL120 RGB lighting

Hi everyone,

I've got a corsair ll120 fan which is not responsive to corsair link. i've set it up fine, connected the fan pin into the fan header in commander pro, the led pin in the 1st header in fan hub, but it just keeps flashing this inner ring pale blue light. i've attached a photo if you want a better grasp of the situation. the other upper isn't lighted on purpose to better show you how urresponsive the rear fan is. any suggestions? thank you in advance.

EDIT: the Ram both in DIMMA1 and 2 it's because the other 2 slots are faulty.

@DevBiker: i've got two 120ll fans, top and rear. i've posted a pic of the functioning one too (rear one is the one i can't control)

@Corsair Lettuce the version is 4.9.6.19

i've also posted how the "faulty" one appears from behind.

This happens: the “faulty” fan keeps flashing blue even if no program tells it to do so and the “normal” behaves normally because I’ve not programmed it in Corsair link to flash any light. At this point I think there’s something not right with the fan itself, even if it seems very strange.

Now that you mention it though, I noticed that only with port 1 I can control the functioning fan.. the other 5 ports seems unresponsive.. even switching to LED channel#2 shows the same problem.. maybe I connected the cables in a wrong manner?

In the end, by switching them between ports 1 and 2 lead me to one fan remaining blue but still unresponsive and one fan without lights becoming unresponsive too.

What I'm trying to figure out is if it's the fan or the fan hub.

The fans themselves operate in a series and they pass the signal "down the line". So the fan in port 1 gets the control signal and then passes a return signal to the fan hub, which then passes it to port 2 ... and so on down the line.

So, in many cases, if a fan is bad, the fans "down the line" also go out.

Well technically it is what is happening.. if I connect the functioning fan in port 1 it works, if I connect it in port 2 with the supposed faulty fan connected to port 2 it also stop displaying any lights. The strange thing is that if a fan is broken then rgb lights should not be displayed at all, instead it keeps this pale blue light on all the time..

That's pretty indicative of a bad fan.

Not strange at all. This is relatively common with bad fans (though uncommon overall).
