How many fans are we talking about? You're also going to have to explain how many of said fans are connected off the RGB header on your motherboard and if they are daisy-chained or if you're using their RGB controller?
right now I've only got two connected because i'm waiting on a splitter i ordered, but when that comes i'll have four connected. I'm using one of the splitters already (noctua na-syc2). I'm not sure what you mean by daisy chained, but i have them all plugged into their rgb controller. One of the two fans is doing what i tell it in the menu, but the other one wont sync with it. The unsynced one is still able to be turned on and off and dimmed so it is connected in some way. I don't know if the connector was plugged in wrong or whether its something else entirely.
These are the fans i have (http://www.coolermaster.com/cooling/case-fan/masterfan-pro-120-ab-rgb/)
Update: It appears that both the fans are doing the opposite to each other. When fan 1 is green and fan 2 is red i try and turn fan 2 green, and it does but fan 1 turns red.
Update #2: fan 2 seems to only go red and green
