Question My Corsair RGB fans work but there is no LED

[lathny]

So i recently bought a new case. The case came with 3 corsair rgb fans and a splitter.
The fans have 2 cables each, one of them is a 3 pin female while the other is a 4 pin female.
The connecter goes to the motherboards rgb-header2 and the other cables go to cha-fan1 cha-fan2 and cpufan-opt.
The fans are working, but they don't light up, i have tried installing rgbfusion and icue but they can't find the fans. What could be the problem?
