2. Key Features
- Multiple Interfaces: Supports up to 9 sets of Addressable RGB (3-pin) and PWM headers, allowing expansion for more devices. Integrates PWM temperature control and AURA Sync interface for efficient heat dissipation and vibrant LED lighting.
- Motherboard Software Compatibility: Compatible with AURA Sync, MSI Mystic Light, Gigabyte Fusion 2.0, and ASRock via a 5V 3-pin Addressable RGB header. Offers 16.7 million static modes and 12 preset lighting effects.
- Intelligent PWM Temperature Control: Connects to the CPU fan interface on your motherboard to access temperature readings. Fan speed automatically adjusts based on CPU temperature, increasing for cooling and slowing down to reduce noise when temperatures drop.
- RF Remote Control: Includes a 21-key RF remote (433.92 MHz) with 368 built-in LED modes. Allows switching between static and dynamic color modes, and adjusting speed and brightness.
- Integrated Magnet: Compact hub with a strong magnetic surface for easy and secure installation onto any metal surface inside your PC case.

4. Setup and Installation
Follow these steps to properly install your GameMax V4.0 PWM ARGB Hub:
- Placement: Choose a suitable location inside your PC case. The hub features an integrated magnet, allowing it to be securely attached to any metal surface.
- Power Connection: Connect the provided SATA power cable from your power supply unit (PSU) to the "POWER IN" port on the hub. Ensure a secure connection.
Important: Do not plug into the wrong power supply interface, otherwise it will burn out equipment!
- Fan Connections: Connect your 3-pin DC or 4-pin PWM fans to the "PWM" and "ARGB" ports on the hub. The hub supports up to 8 fans. Ensure correct orientation for both power (PWM) and lighting (ARGB) connections.
- CPU Cooler Connection: If using a CPU cooler fan, connect it to the dedicated "CPU Cooler Fan Link 1st PWM Port (Red)" on the hub.
- Motherboard Sync (Optional): For motherboard software control (e.g., ASUS AURA, MSI Mystic Light, Gigabyte Fusion 2.0, ASRock), connect the 5V 3-pin ARGB motherboard sync cable from the hub's "M/B" port to the corresponding 5V 3-pin Addressable RGB header on your motherboard.
Note: If using motherboard sync, do not also connect the "RESET" cable for manual ARGB control, as this can cause conflicts. Only link one method.
- PWM Temperature Cable (Optional): Connect the PWM temperature cable from the hub's "FP" port to a CPU fan header on your motherboard to enable intelligent temperature control.
- Front Panel Reset Button (Optional): If you wish to use your PC case's front panel reset button for manual ARGB control, connect the case's reset cable to the "RESET" port on the hub. This allows cycling through lighting modes via the reset button.
Note: This option is mutually exclusive with motherboard sync. Choose either motherboard sync or manual reset button control for ARGB.

5. Operating Instructions
5.1. Using the RF Remote Control
The included 21-key RF remote control provides comprehensive control over the hub's lighting and fan functions. Ensure the hub is powered on.

Figure 5.1: The 21-key RF remote control for the GameMax V4.0 PWM ARGB Hub.
| Button | Function |
|---|---|
| On/Off | Turns the LED lighting on or off. |
| M/B (Motherboard Sync) | Switches between remote control mode and motherboard software sync mode. |
| AUTO | Cycles through the 368 built-in LED lighting modes automatically. |
| S+ / S- | Adjusts the speed of dynamic lighting effects (S+ for faster, S- for slower). |
| M+ / M- | Cycles through the built-in LED lighting modes manually (M+ for next mode, M- for previous mode). |
| Brightness Up / Down | Adjusts the brightness of the LED lighting. |
| Color Buttons | Selects static colors for the LED lighting. |
5.2. Motherboard Software Control (AURA Sync, Mystic Light, Fusion 2.0, ASRock)
If you have connected the hub to your motherboard's 5V 3-pin ARGB header, you can control the lighting effects directly through your motherboard's proprietary software. Ensure the remote control is set to M/B mode (if applicable, or simply ensure the hub is not in manual reset button mode).
- Open your motherboard's RGB control software (e.g., ASUS Aura Sync, MSI Mystic Light Sync, GIGABYTE RGB Fusion 2.0, ASRock Polychrome Sync).
- The connected ARGB devices should be detected.
- Use the software interface to customize lighting effects, colors, and synchronization with other compatible components.
5.3. Intelligent PWM Temperature Control
When the PWM temperature cable is connected to your motherboard's CPU fan header, the hub will automatically adjust fan speeds based on CPU temperature readings. This ensures optimal cooling performance while minimizing noise when the system is under light load.
- As CPU temperature increases, fan speeds will automatically ramp up to provide more airflow.
- As CPU temperature decreases, fan speeds will automatically reduce, leading to quieter operation.
6. Maintenance
The GameMax V4.0 PWM ARGB Hub requires minimal maintenance. To ensure optimal performance and longevity:
- Cleaning: Periodically clean the hub and its connections using a soft, dry cloth or compressed air to remove dust buildup. Ensure the PC is powered off and unplugged before cleaning.
- Connections: Occasionally check all cable connections to ensure they are secure and free from damage.
- Environment: Operate the hub in a well-ventilated PC case to prevent overheating.
7. Troubleshooting
If you encounter issues with your GameMax V4.0 PWM ARGB Hub, refer to the following common problems and solutions:
| Problem | Solution |
|---|---|
| Fans or LEDs are not working. |
|
| LEDs are not synchronizing with motherboard software. |
