On my new pc, I have the cit flash argb case. It comes with 4 fans. They are connected through a load of 4 pin connectors that lead to a sata power cable. there is one of these 4 pins spare. They worked fine before but now the rgb turns off after a few seconds. Would getting a fan hub solve this issue. There is not one there and they cycle through random colours which i would like to change. Its kinda annoying. Its not a power issue because i have a 650w psu and only 550w gets used ever.
