[SOLVED] Plugged RGB fan on jrbg but no light

[Jeff_120]

I plugged my brand new Aerocool rgb fan to my msi b450m board on the jrbg and 3 pins power, the fan works but not its light!
Any solution?

Swapped the plug on the mobo between jrbg1 and 2 and it works.
So the fan is not faulty but I need jrbg2 for my cpu fan.
Mystic light and aerocool app don't see the rgb case fan!
