Connect RGB fan from case to motherboard

Solved

Hello,

I would like to connect the RGB fans from the Antec NX600 case to the MSI MPG Z390 Gaming Pro AC motherboard.
This case includes a controller that connects all the RGB fans (4).
From this controller, I have either a Molex connector to connect to the PSU or a cable that splits into 3 plugs. I'm not sure how to connect these 3 plugs to my motherboard.

Can someone help me?
Best regards.
Olivier S.

Hello zire478, have you resolved your issue since then? Because I'm having the same problem as you, I don't know where to connect the power fan in molex from the controller. I used an adapter to convert it to sys fan, which I connected to the motherboard, but I can't get the fans to work. This case really lacks a manual...

Hello,
It's impossible to override the controller of the case to adjust the fan speed.
So I had to change the case... I got a Corsair.

The molex connector must be powered by a molex from your power supply.

Hello, these are the same connectors as the "CPU FAN" except they are called "SYS FAN" (system fan) and there is a keying to avoid misorienting them, it works with 3 or 4 pins.

Hello,
actually all my case fans are connected to a controller, and from this controller comes a Molex connector and one connector that splits into 3 (1 SYS_FAN connector but with 2 wires and 3 holes + 1 JRAINBOW connector + 1 3-hole connector but with only 1 wire). I don't know what the latter is for.

Okay, maybe some cables are only there to fit a maximum of motherboards, it would be necessary to consult both the case manual and that of the motherboard.

Well, that's the problem.. in the motherboard manual I'm not going to have any information about the case cables, and regarding the case, there's no information about these cables!! Not good...

My fans are connected to an original controller. Do you find it normal that from this controller there is a cable (4 wires) with at the end

a 4-pin sys_fan type plug but only 2 wires
a jrainbow type plug (4 pins but one blocked) and from this plug with a 3rd wire with a 3-pin connector (the wire arrives in the middle).

How can I connect this to the motherboard to make the fans work both for speed control and for RGB lighting?

I remind you that I can only make them work with the molex plug coming from the controller linked to the power supply.

Can someone help me?
