Overview
The be quiet! PURE WINGS 3 140mm PWM Black is a 140mm case fan from the renowned German PC cooling specialist. With a maximum speed of 1,200 RPM and a noise level of just 21.9 dBA, it is engineered to deliver effective airflow while keeping acoustic output to a minimum. PWM support allows the motherboard to dynamically adjust fan speed, making it an excellent choice for users who want to fine-tune the balance between cooling performance and system noise. This fan is versatile enough for use as an intake or exhaust fan in PC cases, as well as on CPU cooler radiators. The larger 140mm size moves more air at lower RPMs compared to 120mm fans, offering superior cooling efficiency in quiet operation. Its all-black, minimalist design blends seamlessly into any build aesthetic. Positioned in the mid-range market, the PURE WINGS 3 series inherits be quiet!'s legacy of silent operation while remaining accessible in price. It is a strong contender for anyone building a quiet-focused PC without breaking the bank.
Compatibility Guide
The fan measures 140mm x 140mm x 25mm, a standard size compatible with most PC cases, CPU coolers, and radiators that support 140mm fans. It uses a 4-pin PWM connector, ensuring broad compatibility with modern motherboards for automatic speed control. Before purchasing, verify that your case or radiator has 140mm mounting points. When installing in the front or top panel, check for clearance with the motherboard, GPU, or other components. For radiator use, ensure the combined thickness of the radiator and fan (25mm) fits within your case.
Product Info

The fan comes with a standard 3-year manufacturer's warranty. In the market, it occupies a mid-range position. Compared to the higher-end Silent Wings 4 series, it uses a different bearing type and comes with fewer accessories, but its real-world noise and cooling performance are still very impressive for the price. While specific TDP or CFM ratings are not provided, the 1,200 RPM max speed and 21.9 dBA noise figure are well-suited for quiet PC builds.
Best Use Cases
Silent PC Builders: With a noise level of only 21.9 dBA, this fan is virtually inaudible during idle and light workloads. It is ideal for home theater PCs, office computers, or any system where silence is a priority. Gamers Seeking Balanced Cooling: The 140mm size delivers ample airflow at low RPM, keeping your system cool during gaming sessions without excessive fan noise. PWM control ensures the fan ramps up only when needed. * Budget-Conscious Enthusiasts: This fan offers be quiet!'s renowned engineering at a very accessible price point. It is a great option for outfitting an entire case with matching, high-quality fans without a large investment.
Things to Consider
This is a 140mm fan, so it will not fit in cases or radiators designed only for 120mm fans. Always check your case specifications before buying. With a maximum speed of 1,200 RPM, it may not provide sufficient cooling for extremely high-heat components in overclocked systems. For a high-end CPU or GPU radiator, you might need multiple fans or consider a higher-RPM model like the Silent Wings 4. The package includes only the fan and mounting screws. Vibration dampeners or extension cables are not included and may need to be purchased separately if required.
