The NZXT H9 Flow RGB combines powerful cooling with stylish presentation for enthusiasts and show builds. The combination of a dual-chamber design, F420 RGB Core fan, and panoramic glass makes it the ideal case for high-end systems focusing on aesthetics and airflow.
- F420 RGB Core fan delivers 98.6 CFM airflow with vibrant RGB lighting
- Dual-chamber layout improves cooling and cable management
- Supports up to 10 fans – nine 140 mm + one 120 mm at the rear
- Supports 420 mm radiators at the top and front
- Back-Connect compatible with ASUS BTF & MSI Project Zero
Powerful RGB cooling included
The pre-installed F420 RGB Core is a high-performance single-frame fan – 2,000 RPM, 3.2 mmH₂O static pressure, and RGB lighting make it the ideal solution for stylish front cooling. It is complemented by a quiet F120Q fan at the rear.
Structured airflow & dual-chamber system
By separating the power supply, drives, and motherboard, the H9 Flow RGB optimises heat distribution inside. Angled fan mounts and finely perforated mesh panels support targeted airflow for maximum cooling performance for GPUs up to 435 mm in length.
Showbuild-ready & future-proof
Two frameless tempered glass panels provide a 360-degree view of your components – ideal for RGB setups. The case is compatible with rear connections such as ASUS BTF and MSI Project Zero and offers modern connectivity with USB-C, 2x USB-A, and a headset port.
