First, I apologize if my terminology is incorrect. I am out of my element, but trying to figure this out.
I bought a cheap PC case in Korea, and it included an RGB LED strip on the front of the case which has a cable attached via 4-pin to the strip itself, but on the other end of the cable, it is reduced to two pins. I am guessing that if I were to plug a full RGB cable (4pin to 4pin) to an RGB controller, I could control the RGB strip more precisely. However, the intention of this 2 pin seems to be simply to toggle the RGB LED strip through a series of presets, which is done via a button on the front of the case.
However, I also purchased 6 cheap Korean RGB case fans, which are also controlled by a 2 pin rgb connector. I believe if I plug them individually into the 2 pin connector which goes to the button on the case, they can each individually be cycled through preset patterns.
My goal, and my question, if I were to find a hub or splitters which allowed me to connect all of these 6 fans and LED strip to the button on the case, would I be able to cycle them through the preset patterns simultaneously via one button? I believe they all have some memory system which allows them to remember which part of the cycle they left off on when the system is powered down, so I would need to make sure they are all synchronized before connecting them to each other, but if this would work, where would I be able to purchase a 2-pin RGB hub/splitter?
I believe the answer is more of an electronics one than RGB specific, as the switch is probably sending a very simple message to trigger the RGB LED systems to move onto the next pattern in the cycle rather than sending specific RGB data.
Thank you for your help.

The RGB 2pin LEDs can be programmed to sequence thru 1 of 8 colours using a power-off glitch as small as 1 us. Thus they may all be synchronized but need a number of pulses to achieve a steady colour.
I don’t know the sequence but I suspect combinations of 1 , 2 and all 3 LEDs to make up these colors.
