Review: Be Quiet out performs my expectations once again. - Be Quiet! Light Wings 120mm PWM: Silent Symphony with a Touch of RGB Flair Overall Rating: 4.5 out of 5 stars For: Silent PC enthusiasts, RGB lovers seeking low noise, case fan and radiator upgrade seekers Against: Limited ARGB control options, higher price than some non-RGB alternatives Performance: 5 out of 5 stars Be Quiet! lives up to its name with the Light Wings 120mm PWM. It delivers exceptional cooling performance while remaining whisper-quiet. Even at its maximum 1700 RPM, the noise level stays incredibly low, making it a dream for silent PC builds. The airflow optimization ensures efficient heat dissipation, making it suitable for both air coolers and radiators. Features: 4 out of 5 stars The Light Wings 120mm boasts a robust build quality with a sleek black design. The included PWM control allows for flexible fan speed adjustments based on your needs. The highlight, of course, is the vibrant ARGB lighting that adds a touch of personal flair to your PC. However, unlike other RGB fans, the control options are limited to the included hub, lacking software control or integration with major motherboard ecosystems. Value: 4 out of 5 stars While the Light Wings 120mm falls on the pricier side compared to some non-RGB fans, its exceptional quietness and build quality justify the premium. If you value silence and want a touch of RGB without sacrificing performance, it's a worthwhile investment. Things to Consider: Limited ARGB Control: No software control or motherboard integration for the lights, relying solely on the included hub. Higher Price: More expensive than some non-RGB alternatives with similar performance. Black Design: Might not be ideal for builds with different color schemes. Final Verdict: The Be Quiet! Light Wings 120mm PWM is a remarkable achievement in balancing powerful cooling with near-silent operation. Its sleek design, vibrant ARGB lighting, and robust build quality make it a top choice for silent PC enthusiasts and RGB lovers alike. While the limited ARGB control and higher price tag are minor drawbacks, its overall performance and quality shine through. If you prioritize silence and want a touch of RGB magic in your PC, the Light Wings 120mm PWM is a worthy addition to your symphony of silence.
Review: Fantastic PC Fans! - These fans are awesome!! I had a faulty board, so I haven't had the opportunity to use the PC extensively yet. However, the installation was straightforward, the RGB controller was easy to mount (using 2-sided sticky tape on the HDD side of the case), and the fans are of excellent quality. Upon initial power, they ran perfectly and were very quiet. I previously had a lower quality pre-built, and those fans were 2-3 times louder than these. The RGB lights are fantastic, not too bright or crazy, just a reasonable amount. I highly recommend this set!

### ⭐⭐⭐⭐⭐ WOW!... Nothing but great quality stuff (case fans in this case) and more from ~be quiet!~
*by D***D on June 24, 2026*

For only $50 bucks, for No Less than 3! 140mm PMW_high-speed, ARGB_ring, WITH "Fan Hub" TOO!... Super well package with all 3 fans in individual protective reinforce carboard sleave-box Am replacing the boring hi-spd fans on another great quality be quiet part (420 AIO) with these... So i'll be getting the FULL fan show -PLUS- top cooling perf from the incoming [white] Light Base 900 FX case... Case comes 1 rear rear exh fan and 3 White Light Wings [reverse] intake fans Front... adding 3 White LW's [reverse] pointing directly at the 5080 from the bottom/or side, and "these 3" hi-spd on the radiator exh (might use one or 2 of the black ones that came with the 420 cooler to place in the seperate PSU section and rig it to point directly at the CPU_back-plate on the MB... and LoL... maybe even another poing at the back of the PSU ... If i configure all 12! fans right, i'll get the positive desired positive pressure and my rig won't sound like a Warthog flying low for a strafing run ... BRRRrrrrrrrTT!! (might add it as a fun win-boot chime though :)
