The be quiet! Pure Wings 3 140mm PWM is a computer fan designed for use in computer enclosures, particularly in gaming and multimedia systems as well as in demanding PC builds with water or air cooling. The fan has a 14 cm diameter and is finished in black. It is designed for quiet and consistent cooling performance and is especially suitable for systems where low noise levels are a priority.

Applications

The fan is designed for use in computer enclosures, particularly in systems requiring quiet yet efficient airflow. It is suitable for gaming PCs, multimedia systems, and quiet systems where low operating noise is important. The optimized fan geometry ensures high static pressure performance, making it especially suitable for radiators and heatsinks with high resistance.

Features and Equipment in Detail

The fan features a 4-pin connector that supports Pulse Width Modulation (PWM). This allows for precise speed control via the motherboard, enabling the fan to automatically adjust its speed according to system load. The maximum rotational speed is 1200 revolutions per minute (RPM), achieving an airflow of 97.5 m³/h. The maximum static pressure is 0.96 mmH2O, enabling efficient airflow through densely packed heatsinks. The fan operates with a rifle bearing, which allows for a lifespan of up to 80,000 hours at an operating temperature of 25 °C.

Technology Explained Simply

The fan is equipped with a closed-loop motor that maintains constant rotational speed regardless of airflow resistance. This ensures stable cooling performance, even under high airflow resistance. The newly designed fan blades and optimized blade angle increase static pressure and improve airflow. The fan construction minimizes air loss through an optimized frame shape, enhancing overall performance. Operation begins at very low RPM, contributing to quiet operation. Power supply is via a voltage range of 5 to 13.2 V, with a nominal voltage of 12 V. Power consumption is 3.6 W, equivalent to a current draw of 0.06 A.

Compatibility and Accessories

The fan is designed for standard 140 mm mounting holes and can be installed in computer enclosures with corresponding fan openings. The cable length is 0.46 m, allowing flexible placement within the enclosure. The package includes four screws required for mounting the fan to the enclosure openings. The screws are suitable for standard mounting and ensure secure fastening.

Installation and Mounting

Installation is performed by securing the fan to the designated mounting points in the computer enclosure using the included screws. The 4-pin connector is connected to the corresponding fan header on the motherboard, activating PWM control. The cable length of 0.46 m allows flexible placement, even in larger enclosures. No additional tools or components are required for installation.

Operational Advantages

The fan is characterized by high durability and quiet operation. The rifle bearing technology ensures long service life and low noise generation. Operation at low RPM enables very quiet cooling, while the maximum speed of 1200 RPM provides sufficient airflow for effective cooling. PWM control allows adaptive speed adjustment according to system load, saving energy and minimizing noise levels. The airflow of 97.5 m³/h and static pressure of 0.96 mmH2O ensure efficient cooling performance, even in systems with high airflow resistance.
