Optimal cooling performance for large systems

With three 140mm fans combined, the ZA‑420B provides extensive airflow for powerful radiators or mesh fronts. The airflow of up to 125.39m³/h ensures stable temperatures – even under heavy system load.

Integrated ARGB for seamless aesthetics

Thanks to the 5 V 3-pin ARGB, the fans can be individually customised and synchronised in colour – compatible with common motherboards and controllers. The lighting is evenly distributed across the entire composite frame.

Quiet continuous operation & solid build quality

The hydraulic bearings ensure reliable, low-noise operation – even during extended use. With a max of 32.2 dB(A), the triple fan remains pleasantly quiet and impresses with high durability and a stable design.
