140 mm PWM case fan for quiet builds

The be quiet! Silent Wings 4 BL096 is a single 140 mm case fan built for systems that prioritise low noise. It uses a fluid-dynamic bearing and a six-pole motor to keep vibration minimal while delivering 51 to 87 CFM of airflow at speeds below 1600 RPM.

Suited to silent PCs and high-pressure cooling

This fan suits builders who want near-silent operation on radiators or dense heat sinks where static pressure matters. It is not for buyers who need a bundled fan controller, RGB lighting or a multi-fan kit in a single package.

Check mounting and header before ordering

Verify your chassis or cooler has 140 mm mounting points with 25 mm clearance for the frame thickness. Ensure the motherboard or fan hub provides a standard 4-pin PWM header for speed control. The box includes anti-vibration push pins and screws for either mounting method.

Questions about this item

What motherboard header does the 4-pin PWM connector on this fan plug into?

It plugs into any standard 4-pin PWM fan header on the motherboard for automatic speed control.

Will the 140mm frame and 25mm thickness fit the mounting points on my older case?

The fan uses the standard 140mm square frame with 25mm depth, matching the screw-hole spacing used on most cases for years.

How can I confirm the fan is running within its 10 to 15 dBA noise range after installation?

At low PWM duty cycles the fan should be virtually inaudible; use a decibel meter at close range to verify the 10–15 dBA level.
