I should have given explanation to each instead of just drawing circles, what makes sense to me doesn't necessarily make sense to others, sorry about that.
The last picture is the pin connector from the radiator circled in red going to a SATA connector for power, what is it powering I don't know. As for it looking melted, it's probably just the lighting as when I was doing this I didn't see any damage. But the pin connector going to the SATA only has 2 pins vs the 3 pin slots coming from the radiator cable. This cable, the one coming from the radiator, would be the one I would plug into the motherboard if I removed the SATA cable portion. Perhaps the 3rd missing pin is for some sort of control that the SATA cable clearly doesn't need since it's just power? Also just to perhaps clear up any confusion, the wire coming from the radiator isn't powering the fans, those were clearly separate and coming from the fans themselves when I installed them.
To put it simply, wire coming from radiator is hardwired in that ends in a 3 pin female connector. That's plugged into a 2 pin male SATA cable.
As for other wires that came with it, I only have the rgb controller switch. And as far as I can tell the cables coming out of the radiator and CPU block aren't removable and they don't have an extra alot to plug into them as well. I also read there are some "reports" on Amazon, where I bought it, that some do come with the pump in the radiator, but I don't know how much I should trust those.
