So I have everything done with this case but I'm a little stumped with what to connect where with my PWM fan hub. I know the 4pin lead goes to my CPU fan slot on my MOBO, but there are also two SATA and one Female Molex connectors two. I read somewhere that one SATA is for the LEDs and one is to power the fans themselves. If that's the case would both SATAs go to the PSU? But what about the Molex. Like I said I'm a little confused. If someone could throw me a bone and tell me exactly where to plug em in that would be great.
PWM fan hub on Phanteks Primo case

What you describe is not what I have seen in the past. What I saw with this Hub was:
1. The Hub has six 3-pin ports on its sides for fans, of which one is white for Fan #1. ONLY the fan on this port will have its speed reported to the mobo header you connect this Hub to.
2. The Hub has ONE 4-pin male connector on one end labelled to connect to your mobo's CPU_FAN header. The unit also comes with ONE cable to make this connection.
3. On the opposite end the Hub has a male 2-pin connector labeled SATA 12V. The unit comes with ONE cable to connect this port to a SATA power output connector from the PSU. This is how the Hub gets power for all its fans.
4. The Hub also comes with two 3-pin fan Y-splitters. Each of these MAY be used to connect two fans to one of the six Hub ports. Just do NOT use them with the white Port #1. The Hub's specs say you can use up to 5 splitters so that it can power up to 11 fans - they just include two splitters to get to started if you need them.
Phanteks recommends that you connect the Hub's 4-pin fan input to the mobo CPU_FAN header (and labels the Hub port that way) because this Hub MUST have a genuine PWM signal from a 4-pin mobo header using PWM Mode for control. Unfortunately, SOME current mobos have 4-pin SYS_FAN or CHA_FAN headers intended for case fan ventilation that are NOT true 4-pin headers - they operate in Voltage Control Mode and have a useless 4th pin. To avoid having you use such a mobo header and finding the Hub fails to control its fans, Phnateks advises that you always use the CPU_FAN header because all current mobos use true 4-pin headers for that function, and have them pre-set to use PWM Mode for control. When you do this, you also REALLY MUST follow their related instruction: the actual CPU cooler system MUST be plugged into Hub Port #1 (the White one) so that the speed of THAT fan specifically is sent to the CPU_FAN header for monitoring.
