NZXT H9 Flow (2025) – Dual-Chamber ATX Mid-Tower Airflow Case with 4 Pre-Installed Fans & 420mm Radiator Support

Design & Structure
The NZXT H9 Flow (2025) embodies a perfect balance between modern aesthetics and functional airflow engineering. Built with a large dual-chamber layout, it separates the power supply and cables from the main hardware chamber, resulting in superior cooling efficiency and a clean, professional look. The design emphasizes openness and symmetry, enhanced by clear tempered-glass panels that allow full visibility of your system’s components.

Cooling System
Out of the box, the H9 Flow (2025) includes 4 pre-installed fans — three 140 mm intake fans and one 120 mm exhaust — providing balanced, silent airflow for optimal temperature control. The spacious interior also supports additional fans and high-capacity radiators for users who wish to expand their cooling setup.

Radiator & AIO Support
Engineered for flexibility, the case accommodates radiators up to 420 mm in size, making it ideal for high-performance AIO or custom liquid-cooling systems. Its optimized layout allows for front, top, or side mounting options, letting you tailor cooling performance and aesthetics to your preference.

Component Compatibility
The H9 Flow supports ATX, micro-ATX, and mini-ITX motherboards, with ample clearance for long GPUs, large CPU coolers, and multiple storage drives. Thanks to its open interior and modular brackets, installation and future upgrades are straightforward and frustration-free.

Cable Management & Accessibility
NZXT’s signature cable-management system shines in this model, featuring pre-routed channels and Velcro straps for clean organization. Tool-less tempered-glass panels provide easy access to your build while maintaining durability and a secure fit.

Build Quality & Materials
Constructed from premium steel and high-quality tempered glass, the H9 Flow offers outstanding rigidity and a sleek modern appearance. Every cutout, bracket, and edge is precision-engineered to provide long-term reliability and seamless compatibility with modern PC components.

Airflow Optimization
True to its name, the H9 Flow prioritizes unrestricted airflow. The perforated top and side panels ensure efficient ventilation, while the included dust filters keep your system clean and running at peak performance over time.
