NZXT Unveils New H9 Flow Cases and Enhanced Kraken Cooling Solutions for Gaming PCs

PC gaming component manufacturer NZXT has announced an expanded lineup of cases and cooling solutions aimed at improving thermal performance and simplifying PC builds. The new releases include the H9 Flow case series, a compact H3 Flow micro-ATX option, upgraded Kraken Plus AIO coolers, and the company’s first 420mm cooling products.

The flagship H9 Flow series consists of three variants: the standard H9 Flow, H9 Flow RGB, and H9 Flow RGB+. These dual-chamber mid-tower cases support both top and front 420mm radiators, featuring airflow-optimized mesh panels and angled front-right corner fans adapted from NZXT’s H6 Flow design. The cases accommodate rear-connecting motherboards for cleaner cable management and include wraparound tempered glass panels for component visibility.

The premium H9 Flow RGB+ model comes equipped with pre-installed RGB components, including two F420 RGB Core fans and a 120mm RGB Core rear fan, plus an integrated NZXT Control Hub for synchronized lighting and cooling control through the company’s CAM software.

For space-conscious builders, the new H3 Flow delivers micro-ATX compatibility while supporting full-size graphics cards and 280mm front radiators. The case incorporates design elements from the H5 Flow, including an airflow-optimized PSU shroud that enhances bottom fan intake performance. Back-connect motherboard compatibility maintains the compact footprint without sacrificing functionality.

Kraken Plus Series Delivers Improved Thermal Performance

NZXT’s refreshed Kraken Plus series replaces the 2023 Kraken lineup with enhanced cooling capabilities and streamlined installation. The new coolers utilize the NZXT Turbine pump and high-performance fans from the 2024 Kraken Elite, resulting in over 4% better CPU cooling performance according to the company’s thermal resistance testing.

Available in standard and RGB configurations, the Kraken Plus features 1.54-inch square LCD displays capable of showing real-time temperatures, custom images, and GIFs through NZXT CAM software. RGB models include a single breakout cable that integrates fan and lighting control, working with the company’s one-connector RGB Core fans.

The new Kraken Elite 420 RGB represents NZXT’s largest AIO cooler, designed for cases with 420mm radiator support. It features a 2.36-inch customizable LCD display and comes equipped with the F420 RGB Core—a single-frame triple 140mm fan unit that combines high airflow performance with RGB lighting through simplified one-cable connectivity.

The F420 RGB Core is also available as a standalone component and comes pre-installed in the H9 Flow RGB and RGB+ cases, reducing installation complexity through fewer screws, cables, and connectors.

Felix Guerra, SVP of Product Generation & Development at NZXT, emphasized the company’s focus on expanding options while maintaining accessibility. The new products maintain existing pricing structures for screen-equipped AIO coolers while offering enhanced performance and simplified installation across the ecosystem.
