This is my very first PC build, I'm very excited, but also a little bit confused, so I'm sorry if I'm not making much sense or sound a little silly in advance.
I'm using this case that I bought from Newegg, it comes with five pre-installed 120mm blue LED fans, one rear exhaust, two frontal intake, and two topside exhaust. Each fan has a standard 3-pin connector to it, but they also have each their own 4-pin molex attached as well. What is also included in this case is a four-way 3-pin splitter, two are labelled "Fan 1" and two are labelled "Fan 2", and when the case came to me, four of the fans, the two frontal and two topside, were plugged into the splitter, I'm assuming that's how it's supposed to be, but this raises some questions.
1) Where is this splitter recieving it's power from? It's connected to the front panel of the case, where the power button and USB ports are, so is that what will end up powering all four fans? There's a single molex connector that's on it's own coming from the same place, it's not connected to anything or attached to any other wires that's labelled "Power" so I'm assuming so?
2) Since the case clearly comes with it's own fan splitter which I assume provides each fan power, why are the molex connectors necessary? I would think that if the fans are connected to the case and recieving power as such, then each fan having it's own molex connector seems kind of weird, doesn't it? Unless they're used for something else and I just don't know about it.
3) This is the motherboard I plan on getting, under specifications it states that it has four 4-pin chassis fan connectors in it, since 4-pin connectors work with 3-pin fans, and to my knowledge 4-pin allows you to control fan speed and 3-pin just makes the fans run at full speed 24/7, would it be better to just plug the fans into the motherboard and forget about the splitter in the case?
