Setup Guide
- Placement: Utilize the magnetic design of the hub to conveniently place it on any metal surface inside your computer chassis.

- Power Connection: Connect the SATA power cable from your power supply unit (PSU) directly to the hub's SATA power input. This ensures stable power delivery for up to 10 fans.
- PWM Fan Connection: Connect your 12V-4PIN PWM fans to the designated PWM ports on the hub.
- Important: For accurate fan speed reading and PWM regulation, connect one fan to the red-colored PWM port (usually labeled FAN1 or PC IN PWM IN). The motherboard will only recognize the speed of the fan connected to this specific port.
- ARGB Lighting Connection: Connect your 5V-3PIN ARGB fans and other ARGB lighting devices to the designated ARGB LED ports on the hub.
- Caution: Ensure you connect 5V-3PIN ARGB devices only. Do NOT connect +12V 4PIN RGB interface devices, as this can damage the equipment.
- Polarity: Pay close attention to the arrow marked on the ARGB equipment plug and insert it in the direction of 5V on the hub. Incorrect insertion can damage the equipment.
- Motherboard Synchronization (Optional): To synchronize ARGB lighting with your motherboard's software (e.g., ASUS Aura Sync, MSI Mystic Light Sync, ASRock Polychrome Sync), connect the hub's 5V-3PIN ARGB cable to the corresponding 5V-3PIN ARGB header on your motherboard.

- PC Case LED Key Connection (Optional): If your PC case has a dedicated LED control button, you can connect it to the "KEY POWER" port on the hub to control lighting effects directly from your case.
Operating Instructions
Remote Control Functions:
The included RF remote control allows for easy adjustment of fan speed and ARGB lighting effects. Point the remote towards the hub or your PC case (if the hub is inside) to send commands.

- Power Button: Turns the ARGB lighting on/off.
- Speed Buttons: Adjust the speed of the fan effects (if applicable) or lighting animation speed.
- Mode Buttons: Cycle through various pre-programmed lighting effects.
- Color Buttons: Select static colors or color cycling modes.
- Brightness Buttons: Adjust the brightness of the ARGB lighting.
PWM Intelligent Temperature Control:
When connected to a motherboard's PWM header (via the red port), the hub will automatically adjust fan speeds based on the system's temperature, ensuring optimal cooling performance and reduced noise levels.
ARGB Lighting Synchronization:
If connected to a compatible motherboard ARGB header, the hub's lighting effects can be controlled and synchronized with your motherboard's software, allowing for a unified lighting experience across your PC components.
Maintenance
- Cleaning: Periodically clean the hub and its connections with a soft, dry cloth to prevent dust buildup. Ensure the PC is powered off and unplugged before cleaning.
- Cable Management: Regularly check that all cables are securely connected and neatly routed to prevent interference with other components or airflow.
- Environmental Conditions: Operate the hub within standard PC operating temperatures and humidity levels. Avoid extreme conditions.
Troubleshooting
- No Power to Fans/Lights:
- Ensure the SATA power cable from the PSU is securely connected to the hub.
- Verify that your PSU is providing power to the SATA connector.
- ARGB Lights Not Working or Incorrect Colors:
- Confirm that ARGB devices are 5V-3PIN and not 12V-4PIN RGB. Connecting 12V devices will cause damage.
- Check the polarity of the ARGB connectors; ensure the arrow on the plug aligns with the 5V marking on the hub.
- If using motherboard sync, ensure the hub's ARGB cable is correctly connected to the motherboard's 5V-3PIN ARGB header and that motherboard software is configured correctly.
- Try controlling lights with the remote control to isolate the issue (hub vs. motherboard sync).
- Fan Speed Not Regulated by Motherboard:
- Ensure the main PWM fan is connected to the red-colored PWM port on the hub (PC IN PWM IN). Only this port's speed is reported to the motherboard.
- Verify that the hub's PWM input cable is connected to a PWM header on your motherboard.
- Check motherboard BIOS/UEFI settings and fan control software to ensure PWM control is enabled and configured for the connected header.
- Remote Control Not Responding:
- Check if the remote control's battery needs replacement.
- Ensure there are no obstructions between the remote and the hub.
- If your PC case has a "KEY POWER" button connected, try using that to see if the hub responds.
User Tips
- For optimal cable management, plan your fan and ARGB cable routes before mounting the hub. The magnetic base allows for easy repositioning if needed.
- If you are using a mix of fan types, ensure all fans connected to the PWM ports are 4-pin PWM compatible for proper speed control.
- Always double-check the voltage and pin configuration (5V-3PIN ARGB vs. 12V-4PIN RGB) of your lighting components before connecting them to avoid damage.
