InWin Launches its Neptune AN, DN and DN PRO Series of Silent Static Pressure Fans

【Taoyuan, Taiwan, 24th August, 2023】In Win Development Inc. (InWin), a leading innovator in PC enthusiast gaming hardware, has introduced its new AN120/140, DN120/140, and DN120/140 PRO case fans. These silent, high static pressure fans are ideal for air or liquid cooling.


Key Features

Neptune AN, DN, and DN PRO fans feature InWin’s signature Turbine Blade design that angles the blades to channel more concentrated airflow. The fan is molded to the frame to prevent air leakage and noise pollution that standard models tend to emit. The results offer an impressive static pressure of up to 2.95 mm/H2O (DN140 PRO), while operating at a mere 20.3 dBA (DN120 PRO). Get great performance without sacrificing your peace. Control with PWM via a dedicated IC chip (for DN PRO), which can produce as little as 17.2 dBA at 900 RPM (AN120).


DN PRO Series

The Neptune DN120 PRO (120 mm) and DN140 PRO (140 mm) offer superior performance without noise elevation. Its FDB bearing with metal magnetic and copper bearing shields assures quality, backed by a 6-year warranty. The internals feature a large 3-phase, 6-pole motor, which produces powerful performance up to 91.66 CFM (DN140 PRO). The DN PRO fans include brass screw threads preinstalled into each corner, plus two types of longer screws ready for liquid cooling radiators. Highly durable, 500 mm nylon braided extension cables offer more cable management flexibility. 


AN Series

The Neptune AN120 (120 mm) and AN140 (140 mm) fans include radiant ARGB lighting effects that can be controlled from compatible motherboard software to sync with the rest of the PC system’s lighting effects. Both Neptune AN fans are available in triple packs and include InWin’s modular ‘Lock-N-Go’ extension cable system that securely fastens connectors for easier, cleaner cable management.


DN Series

The Neptune DN120 (120 mm) and DN140 (140 mm) fans possess similar features to the AN-series, but their  jet-black design is perfect for low-profile, stealth PC builds and are made for those who prefer a subtler, non-illuminated system.
