Does anyone know what the pinout to the rgb 4 pin connector is ??

If you're talking about normal R/G/B LED strips, it'll usually be one ground pin per color with a common 12v connector. These systems are operated just by the voltage switching to each pin to activate colors.

If it's a custom control scheme like Aura sync, they're usually one 12v pin, one ground pin, and one "Program" pin that assigns colors to all LEDs using some logic in each LED and PWM (iirc) from the controller to assign color, brightness, or any patterns that are happening on the strip.

I found it on the back of the fan where the wires are connected so its ( - DI DO 5V )

That would mean it's ARGB/DRGB. Since standard 4pin is 12V, G, R, B.

I just ended up ordering the corsair hub and controller. Didn't want to dick around with frankensteining the rgb connector.

For anyone else wondering, the DI and DO cables on the sp120 can be combined to work with ( 5V D _ - ) ARGB headers.

Was searching how to connect LL120 4pin argb to non corsair controller. 

 

I will be getting a non corsair controller which is powered from sata and has a 3 pin out male (Argb)

 

So can I connect LL120 4 pin female to 3 pin male out after combining DO and DI. This should work fine?

 

Thanks
