So I recently purchased three RGB fans from Corsair: two HD140s, one for intake and one for exhaust, and one LL120 which I used in place of the stock fan on my Cooler Master Hyper 212 Evo. When I ordered them (on Amazon) the video shown there mentioned that the Corsair Node Pro was included. When the fans arrived, I didn't find it so I went back and found that it would only have been included if I had bought a three pack. So I went back to go order a separate Corsair Node Pro when I realized that it only has two ports in it and I have three fans. Not to mention that the ports in the node look like they're three pin, but the connectors on the cables are four pin. Then I went to look at the commander pro fan controller, only to find that it only has two ports labelled RGB and the rest are labelled fans, USB, and temp. To clarify, the fans each have two leads. One that's just a regular fan power connector which I plugged in to my motherboard fan headers. The second connector is what I'm not so sure about. I assume it's to power the RGB lights. Currently, all three fans are plugged in to my motherboard and they're spinning but not lighting up. So I'm not sure what fan controller/hub to get. In Linus Tech Tips' Ultimate RGB Build Guide video, he plugged all of his fans into the fan hub that came with his three pack of fans, and then he plugged the fan hub into a lighting node pro module. The fan hub that came with the three pack doesn't even look like it's available for separate purchase! So at this point I'm pretty confused. If someone could just tell me what fan hubs/controllers I need to buy to make sure that all of my fans light up, that would be much appreciated. Also, my motherboard only has one additional USB two port, so I don't know if I need some kind of internal USB hub or something. Thanks in advance.
