Removing Side Panels
The main glass side panel can be removed by applying gentle pressure to the notch at the back. The opposite steel side panel also features a notch for removal. Exercise caution when removing the steel panel as it does not sit independently once disengaged.
Removing Top Panel
The top mesh panel is removed by pulling up on a tab located at the back. This reveals the top fan/radiator mounting area and a magnetic dust filter.
2. Motherboard Installation
The H6 Flow RGB supports Mini-ITX, Micro-ATX, ATX, and Extended ATX motherboards. Utilize the pre-installed standoffs and cable routing cutouts for a clean installation.

6. Fan and Radiator Installation
The H6 Flow RGB comes with three pre-installed 120mm RGB fans on the angled front-right panel, optimized for GPU cooling. Additional fan and radiator support is available:

Operating Instructions
Once your PC is fully assembled, follow these steps to operate your system.

The pre-installed RGB fans can be controlled via compatible motherboard RGB software or NZXT's CAM software, depending on your system's configuration. Refer to your motherboard manual for specific RGB header connections and software instructions.
Maintenance
Regular maintenance helps ensure optimal performance and longevity of your PC case.
1. Dust Filter Cleaning
The top panel features a magnetic dust filter that can be easily removed for cleaning. The bottom of the case also has a pull-out filter that extends the entire length of the case.
To clean, gently remove the filters and use compressed air or a soft brush to clear any accumulated dust. Reinstall once clean.
2. General Cleaning
For exterior surfaces, use a soft, damp cloth to wipe down the steel and glass panels. Avoid abrasive cleaners that could scratch the surfaces.
Troubleshooting
If you encounter any issues with your NZXT H6 Flow RGB case, consider the following general troubleshooting steps:
- Power Issues: Ensure all power cables (PSU to motherboard, GPU, etc.) are securely connected. Verify the power supply switch is in the 'on' position.
- Fan/RGB Malfunction: Check all fan and RGB connections to the motherboard or any control hubs. Ensure relevant software (e.g., NZXT CAM, motherboard RGB software) is installed and configured correctly.
- Overheating: Confirm that all fans are spinning correctly and are oriented for proper airflow (intake/exhaust). Ensure dust filters are clean and not obstructing airflow.
