Do you need a rgb hub for it to light up at all? I heard you just can't control the lighting without the hub, not that it can't light up at all without one ?

There's 2 parts to that fan. The fan itself and the lighting. They are seperate. You can run the lights with no fan, or the fan with no lights.

Beyond that is the lighting itself. There's 2 different kinds, and Corsair is as guilty as most with their terminology, they use RGB as a catch-all when there is a distinct difference. This only leads to confusion on the consumer end of things.

The first kind is RGB. That's a non-addressable lighting system that uses 12v, but is controlled by amperage through 3 wires, each wire a color, each wire a ground. The 4th wire is the 12v in. As you raise/lower the resistance on the grounds, every led filament gets brighter or dimmer, the changes to each filament changing your perception of color. High red, high blue, no green = purple. You cannot get Rainbow out of an RGB as all the leds are controlled by the linked grounds.

The second kind is ARGB which is addressable. It uses a 5v system with a data stream to an addressed controller chip. Uses 3 wires only, 5v/gnd/blank/data. Each led is seperate from the others, addressed, so software can send individual addresses a color, the led lights to that color. This makes Rainbow possible.

So depending on if you actually have RGB or ARGB is going to determine which header on your motherboard to use.
JRGB = 12v RGB = 4 wires/4pin
JRainbow = 5v ARGB = 3 wires/4pin

Plug a 5v lighting into a 12v header is a disaster for the fan.

You will need software to control either kind, either Mystic lighting or iCue.

Corsairs fans dont work with your standard 3 or 4 pin rgb headers. You either need one of their controllers or a motherboard with a dedicated jcorsair header on it
Wrong.

Wrong.
So basically I should plug it into JRGB port?

If your fans are RGB, yes. If your fans are ARGB then definitely not. Here's the kicker, the ARGB and RGB plugs are different. So if you've already plugged into the JRainbow and the connector fits perfectly, then you shouldn't then be able to plug into the JRGB port, different headers.

So are your fans rainbow or plain color.

Corsair says RGB everywhere, in big blocky lettering in some points, but shows a picture of rainbow coloring, then halfway down the ad says 'individually addressable' on a large yellow picture. Those are ARGB fans, addressable 5v fans, most definitely do NOT try plugging them into the JRGB header or you'll fry the lighting. Don't understand why companies like Corsair h Ave such a hard time just putting an 'A' in front of the RGB. It's rediculous.

Caveat is that these particular fans, because of the 'Dual Zone' lighting require the use of a Lighting Node Pro and iCue software.
This product is intended as an expansion of the LL120 RGB LED 3 fan kit with lighting Node PRO. The RGB functionality of this product requires a RGB lighting hub and lighting Node PRO
Can also use a Commander Pro.

Oh so it won’t work without a hub

Not by itself, no. The addressing chips only respond to commands from the Commander Pro/Node Pro, the ARGB system addressing is proprietary in these particular fans even if they use standard connections. Basically nothing more than a 'money grab'.

You implied nothing corsair will work without a hub, that's not entirely accurate. And only a select few mobo's like the MSI Meg Ace have that header, which does work with Mystic light or iCue. It's a non-standard header, used with permission or sales cooperation . I've seen multiple corsair fans work just fine without a Node or Commander Pro and that happened right after Corsair moved from its proprietary keyed connector, to the disaster that was a duplicate of the pwm fan connector, to the adopted standard 5050 etc.

But as said, there's a difference between RGB and ARGB. RGB fans don't require a Node or Commander Pro, ARGB does. It gets confusing since Corsair labels everything RGB whether it's addressable or not.

Corsair ARGB don't have Hardware Playback included, that's where once the software sends a color signal to the addressing chip, that chip tells the software 'ok, I'm red now' so the fan picture turns led red, and the software knows its red. All other ARGB has that, but that's why corsair ARGB need the node, the node output takes on that role. Without it, the software has no idea of brightness, voltage flow, amperage totals etc. RGB doesn't require any of that since there is no addressing chip and other functions such as impedence and amperage on the seperate grounds are controlled from a single buss on the motherboard.

"Corsairs fans dont work with your standard 3 or 4 pin rgb headers. You either need one of their controllers or a motherboard with a dedicated jcorsair header on it"

Partially wrong would have been more accurate, so my apologies for that.

Ive never seen a corsair argb/rgb fan that works being plugged into a standard 3 pin 5v or 4 pin 12v motherboard header. Every single one ive seen has had to be plugged into one of their controllers. Unless you buy a separate 3rd party adapter to be able to plug it into your motherboard. Which models of corsair fans have you seen that work without one of these adapters or without one of their controllers? (They have more controllers than just the node/commander pro). Obviously just talking rgb here not the fan itself
You implied nothing corsair will work without a hub
No, I said “corsair fans” which doesnt even come close to implying that nothing with corsair branding will work without a hub. Also when I say “corsair fans” I’m implying the rgb not the fan itself, which should be obvious given the topic.
