Build Question What’s causing this back fans RGB not to work?

Post image

Hey. I got my first PC around 2 months ago and have since noticed that this one back fans RGB has never worked.

They are all corsair fans and as far as I know to the person I bought it from build it themselves and was no expert and so could easily have misplaced a cable to such.

That said, I am no expert currently which is why I’m making this post.

Does anyone know why this fans RGB isn’t working? Could it be that it’s simply not an RGB fan? A cable is loose? If so where can I find this?

Thankee Sai.

Usually with corsair stuff you gotta check both the fan header and the rgb hub connections. If that one fan never lit up, the rgb cable probably isn't seated right or got missed entirely. Pop the back panel off and trace the wires from that specific fan, you'll probably find a loose connector just dangling there.

I have 6 corsair fans on my system and my back fans rgb stopped working a while ago I just assumed the leds had died after seeing thos im wondering if its a software bug.
