Hi! This is my first time on this forum, I figured I would find some answers here. I am completely new to the PC building community, or "PC master race" some would call it. :lol:
Anyways, my problem is that I got no idea where to plug in the "4-pin RGB LED connector" for the 2 Vegas X7 fans I bought. I have the "Fractal design Focus G Black" case, which comes with 2 built-in fans. I figured how to plug in those with no problem, they just had 3 pin connector which is the fan and the white LED lights on it. And I managed to connect one of the vegas x7 fans without the RGB lights on but i ran out of header space, so I need a splitter to connect the last one... so I'm sitting with one fan that isn't running.
Anyone know where I can connect 4-pin RGB connectors on the motherboard?
