ROG Hyperion GR701 - ARGB wiring confusion (using included hub)
Hi everyone,
I’m hoping someone with an **ASUS ROG Hyperion GR701** who is using the included fan/ARGB hub can help me out. ASUS’s documentation on this wiring is pretty confusing, although it may also just be a skill issue on my end but I'm so lost and really want to fix this.
# Hardware
* **Case:** ASUS ROG Hyperion GR701 * **Motherboard:** ASUS ROG Maximus Z790 Formula
# Current hub wiring
* **MB PWM** → connected to `CHA_FAN2` on the motherboard * **BOARD ARGB** → connected to the small ARGB connection on the rear/left side of the case * **FIO ARGB** → connected to the top/front I/O controller * **EXP-ARGB** → unused and still capped
# What is currently working
* All fans spin normally. * All RGB devices connected to the hub light up. When I switch to the MB mode by holding the button on the top of the case, all the on the fans turn off. * The lighting button on the front of the case can cycle the hub-connected devices through different colors and effects, so the hub and case controller appear to be functioning. * Armoury Crate detects and controls the motherboard, GPU, keyboard, and mouse normally. * The Corsair RS140 ARGB fans connected to the Hyperion hub do not appear individually in Armoury Crate, which I understand is expected because they are standard 5V ARGB fans rather than USB/iCUE-controlled devices, they change color when I press the RGB button on the top of the case. * The ROG Thor PSU and the lighting connected through the Hyperion hub do not respond to Aura Sync but work when I press the rgb button.
# The problem
Aura Sync will not control any of the RGB devices connected through the Hyperion hub.
The motherboard’s `ADD_GEN2_1` and `ADD_GEN2_2` headers are both currently empty.
There is one loose cable coming from the top/front case controller labeled **FOR MOBO**. It is a male 3-pin 5V ARGB connector with the `OO_O` pin layout.
The motherboard’s `ADD_GEN2` headers are also male, so they cannot connect directly.

Unfortunately, those discussions either bypass the included hub or never clearly explain how the stock Hyperion hub/controller is supposed to connect to the motherboard for Aura Sync.
# My question
If you are using the stock Hyperion fan/ARGB hub, what exact cable connects the case controller or hub to the motherboard’s `ADD_GEN2` header?
Does the male **FOR MOBO** connector require a female-to-female ARGB adapter or splitter, or am I missing another factory cable somewhere? The photo below is the cable that is unplugged, which has the FOR MOBO on it; it's coming from the top of the case where the power button and such are.
