I have 2 fans on the front of my computer panel. Both are Corsair LL120mm rgb fans. One of them is has started to not synchronize with the the fan. When setting it to a solid color, it seemed fine. But when changing it to either spiral rainbow or anything that involves showing multiple colors at the same time, the rgb lighting begins to lag out and stops moving. The fan is working fine however, so I'm not sure whats going on.
