NZXT CM-H92FW-01 H9 Flow (2025) White ATX Mid-Tower PC Case

Built for high-performance builds

The H9 Flow is a spacious mid-tower ATX case designed for high-performance builds that prioritise airflow and aesthetics. Its dual-chamber layout separates the motherboard, GPU and CPU cooler from the power supply and drives, improving thermal performance and cable routing. Perforated steel panels and angled front-right fans feed cool air directly to the hottest components. The case ships with three 140 mm fans in the front-right chamber and one 120 mm fan at the rear.

Check motherboard and GPU clearance

Verify that your motherboard is ATX or E-ATX and that it fits the dual-chamber layout, including ASUS BTF or MSI Project Zero back-connect designs. The front-right chamber accepts graphics cards up to 435 mm long, so measure your card before ordering. Radiator mounts on the top and front-right support up to 420 mm units; confirm your cooler dimensions match. Ten fan mounts are available — nine for 140 mm fans and one for a 120 mm rear fan — plan your fan count accordingly.

Thermals noise and power draw

The pre-installed F140Q and F120Q fans run on 3-pin DC control, letting the motherboard adjust speed based on temperature. With all four fans spinning at low RPM the case moves a large volume of air through the mesh panels while keeping noise low. Under heavy loads the dual-chamber design isolates GPU heat from the CPU area, helping both components stay cooler without raising fan speeds dramatically. The open mesh and ten possible fan positions give you headroom to scale airflow up or down as your build demands.
