Motherboard fan headers

[Moonlight8382]

So I'm about to build my first PC and I've noticed that the motherboard I got has one fan header for the cpu. However, I have the cpu cooler and 4 additional fans that came with the case. All the case fans are connected to a one piece thing as seen below with 4 pins at the end. How do I connect the fans to the one header?

Those are molex connectors, you connect them to your power supply.

I'm fairly certain that Molex (what you have pictured) can only provide power to whatever component it is attached to. My suggestion is to buy a fan controller, which would simply take power from molex or SATA and also use your motherboard header for control.

They are Montech fans just an fyi. So buy a fan controller and connect it to the SATA cable from the psu?

If they're 3-pin fans, you can also power them off one header by just stacking the Molex connectors and plugging in one of the 3-pin cables-- it'll effectively act as a splitter.

@The_russian Wait, so I just connect the molex 4 pin directly to a SATA 4 pin connector on the psu?

Not to a SATA connector, to a molex connector on the psu. Molex and SATA are two different things and one can't plug into the other.
