The InWin Neptune AN120/AN140 is a series of silent static pressure fans designed for computer cases, featuring ARGB lighting and specialized turbine blade design for efficient and quiet cooling. The series includes both 120mm (AN120) and 140mm (AN140) fan sizes, available in triple packs.
Function Description:
The primary function of the InWin Neptune AN120/AN140 fans is to provide effective cooling for computer components by generating static pressure, which is crucial for pushing air through restrictive environments like radiators or dense component layouts. The "Silent Static Pressure Fan" designation highlights its dual focus on high performance and low noise operation. The integrated Addressable RGB (ARGB) lighting allows for customizable aesthetic effects, enhancing the visual appeal of a PC build. The specialized Turbine Blade design is engineered to optimize airflow and minimize noise, contributing to a quieter cooling experience.

Usage Features:
- PWM Control: The fans utilize Pulse Width Modulation (PWM) for precise speed control, allowing the motherboard to adjust fan RPM based on system temperature, optimizing cooling performance and noise levels.
- ARGB Lighting: Addressable RGB lighting provides extensive customization options, enabling users to synchronize lighting effects with other ARGB components or create unique visual themes within their PC case.
- Turbine Blade Design: This specialized design is engineered to maximize static pressure and airflow while minimizing turbulence and noise, making them suitable for use with radiators or as case fans where air needs to be pushed through obstructions.
- Extension Cables: The triple packs include ARGB Extension Cables (500 mm x 2) and PWM Fan Extension Cables (500 mm x 2). These are crucial for managing cable length, especially in larger cases or when connecting fans that are far from each other or the motherboard. This flexibility ensures clean cable routing and proper connectivity regardless of component placement.
- Airflow Direction Indicator: Each fan features an arrow indicator to clearly show the intake direction of the air, simplifying installation and ensuring correct airflow configuration within the PC case.
- Easy Installation: The fans are designed for straightforward installation into PC cases, typically mounted with screws in designated areas. The non-modular fan-to-fan cables simplify daisy-chaining multiple fans for both power and ARGB signals.
Maintenance Features:
- Long Lifespan Sleeve Bearing: The use of a Long Lifespan Sleeve Bearing contributes to the fan's durability and longevity, with an MTBF of over 36,000 hours, reducing the need for frequent replacement.
- RoHS Compliance: InWin products, including the Neptune AN120/AN140, comply with RoHS regulations, indicating adherence to standards for restricting hazardous substances, which is beneficial for environmental and health considerations.
- Troubleshooting Guide: The manual provides basic troubleshooting steps, such as checking system power and connector connections, to help users resolve common operational issues. For more complex problems, users are directed to the InWin Forum for technical support.
- Important Notes for Care:
- Proper Installation: Users are advised to follow installation instructions carefully to ensure correct setup and operation.
- Temperature Control: Store the fans away from high temperatures and heat sources to prevent damage.
- Impeller Protection: Avoid placing anything in the impeller to prevent damage to the fan blades or motor.
- No Modifications: Do not modify the wires or connectors provided by InWin to maintain product integrity and safety.
- Blade Safety: Do not touch the fan blades when the fan is in operation to prevent injury.
- Intended Use: The fan should only be used in a computer case as intended.
- Liquid Avoidance: Keep the product away from any liquids to prevent electrical damage or malfunction.
The InWin Neptune AN120/AN140 series offers a blend of performance, aesthetics, and user-friendly features, making it a suitable choice for PC builders looking for effective and visually appealing cooling solutions.
