be quiet! Pure Wings 3 PWM high-speed - Black

Its primary advantage is its high static pressure, making it exceptionally effective for cooling radiators and heatsinks where air needs to be pushed forcefully through dense fins.

PWM (Pulse-Width Modulation) support allows the fan's speed to be dynamically controlled by your motherboard or fan controller based on system temperature. This means it can run slower and quieter when your system is cool, and ramp up when needed for maximum performance.

The fan is equipped with rifle bearing technology, which provides a long operational lifespan of up to 80,000 hours.

It is compatible with computer cases that have 140mm fan mounting points. Ensure your case supports this fan size.

The fan provides a maximum airflow of 122.6 m³/h (72.2 cfm) and a maximum air pressure of 2.44 mmH2O.

While be quiet! fans are known for quiet operation, this is a high-speed model. At its maximum 1800 RPM, it produces 30.5 dB of noise. For a truly silent build, you might consider lower-RPM variants or adjust fan curves to prioritize silence over peak cooling.

The product is sold as a single fan unit (Quantity per pack: 1 pc(s)).

Ensure the 4-pin PWM connector is securely seated in the motherboard or fan controller. Verify that the fan header is enabled and providing power in the system's BIOS/UEFI settings. Check if the fan is connected to a PWM header for variable speed control; if connected to a 3-pin header, it should run at full speed unless the header is set to a specific voltage profile.

At maximum speed (1800 RPM), the fan produces 30.5 dB of noise. Adjust fan curves in your BIOS/UEFI or fan control software to reduce speed under lighter loads. Ensure the fan is not vibrating against other components or the case; use rubber grommets or anti-vibration mounts if necessary.

Confirm the fan is connected to a PWM header. Check the fan's speed-regulating motor for obstructions. Ensure your motherboard's BIOS/UEFI is updated to the latest version for optimal fan control compatibility.
