3.2 Motherboard Installation
- Ensure the appropriate standoffs are installed for your ATX motherboard.
- Carefully place the motherboard into the chassis, aligning it with the standoffs and I/O shield opening.
- Secure the motherboard with the provided screws.
- For back-connect motherboards (e.g., ASUS BTF, MSI Project Zero), utilize the dedicated cutouts and mounting points for a clean, cable-free aesthetic.

5. Maintenance
Regular maintenance helps ensure the longevity and performance of your PC case and components.
- Dust Filters: The H9 Flow includes removable dust filters on intake areas (e.g., bottom, top). Periodically remove and clean these filters with compressed air or water (ensure they are completely dry before re-installation).
- Exterior Cleaning: Wipe down exterior surfaces with a soft, damp cloth. Avoid abrasive cleaners. For tempered glass panels, use a glass cleaner and a microfiber cloth.
- Internal Dusting: Every few months, open the case and use compressed air to remove dust buildup from fans, radiators, and other components.
6. Troubleshooting
This section addresses common issues you might encounter.
- System Not Powering On:
- Check all power connections to the motherboard, CPU, and GPU.
- Ensure the PSU is switched on and connected to a working power outlet.
- Verify front panel connectors (power switch, reset switch) are correctly attached to the motherboard.
- High Component Temperatures:
- Confirm all case fans and CPU/GPU coolers are spinning correctly.
- Check for dust buildup on fans and radiators; clean if necessary.
- Ensure proper airflow direction (intake/exhaust) for all fans.
- Verify thermal paste application on CPU cooler.
- Excessive Noise:
- Identify the source of the noise (fans, pump, HDD).
- Ensure all screws are tightened to prevent vibrations.
- Check fan blades for obstructions or damage.
