- Connect Power: Connect the provided SATA power cable to the hub's power input port and to an available SATA power connector from your Power Supply Unit (PSU). Ensure a secure connection to the SATA port closest to the PSU for optimal power delivery.
- Connect to Motherboard (Optional for Sync):
- For PWM fan speed control via motherboard, connect the hub's PWM signal cable to a 4-pin PWM fan header on your motherboard (e.g., CPU_FAN or CHA_FAN).
- For ARGB lighting synchronization via motherboard, connect the hub's ARGB signal cable to a 5V 3-pin ARGB header on your motherboard (e.g., ADD_HEADER or D_LED).
- Connect Fans:
- Connect your CPU cooler's 4-pin PWM cable to the designated red PWM port on the hub. This port is typically used for the primary fan whose speed will be monitored.
- Connect other 4-pin PWM fans to the remaining PWM ports on the hub.
- Connect 5V 3-pin ARGB cables from your fans and other lighting equipment to the ARGB ports on the hub. Remember the safety note regarding 5V 3-pin connections.
- Mount the Hub: The hub features a magnetic design for easy mounting. Simply place it on any metal surface inside your PC case.

- Power Button: Turns the lighting on/off.
- Speed Buttons: Adjust the speed of dynamic lighting effects.
- Mode Buttons: Cycle through various pre-programmed lighting modes.
- Color Buttons: Select static colors for your ARGB devices.
- Brightness Buttons: Adjust the brightness of the lighting.
- Fan Speed Buttons: Control the speed of connected PWM fans (if not controlled by motherboard).
Motherboard Synchronization:
If connected to a compatible 5V 3-pin ARGB header on your motherboard, you can control the lighting effects through your motherboard's native RGB software. This allows for unified lighting across all compatible components in your system.

4. Maintenance
To ensure optimal performance and longevity of your ARGB Fan Hub, consider the following maintenance tips:
- Dust Removal: Periodically clean the hub and surrounding cables to prevent dust buildup, which can affect performance and aesthetics. Use compressed air or a soft brush.
- Cable Management: Ensure all cables are neatly routed and secured to prevent accidental disconnections or interference with other components.
- Connection Check: Occasionally verify that all fan and ARGB connections are secure and properly seated.
5. Troubleshooting
If you encounter issues with your TUMMASTER J-10 ARGB Fan Hub, try the following steps:
- No Power/Lights:
- Check the SATA power cable connection to both the hub and the PSU. Ensure it is fully seated.
- Verify that your PSU is powered on and functioning correctly.
- Fans Not Spinning/Incorrect Speed:
- Ensure all 4-pin PWM fan cables are correctly connected to the hub.
- If using motherboard control, check your motherboard's BIOS/UEFI settings or fan control software to ensure fans are configured correctly.
- If using the RF remote, try adjusting fan speed settings.
- Ensure the CPU fan is connected to the red PWM port for proper monitoring.
- ARGB Lights Not Working/Incorrect Colors:
- Verify that all 5V 3-pin ARGB cables are correctly connected to the hub, paying attention to the arrow alignment.
- If using motherboard sync, check your motherboard's RGB software settings.
- If using the RF remote, try cycling through different modes and colors.
- Confirm that no 12V 4-pin RGB devices are connected to the 5V 3-pin ARGB ports.
- Remote Control Not Responding:
- Ensure the remote's battery is functional.
- Check for any obstructions between the remote and the hub.
