    • A high-quality PWM Fan
Style: 140mm PWM
Quiet operation, nice even LED lighting, moves a lot of air at low RPM. Product quality is very, very good. PWM type of fan, would most definitely buy again.

    • Be Quiet out performs my expectations once again.
Style: 120mm PWM high speed
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. ... show more

    • Great and quite fans!
Style: 140mm PWM high speed
I added these fans to my be quiet! Shadow Base 800 FX case. These fans are built very well and are really quiet even at full speed. The cooling these help provide is very good being 140mm. The LEDs work very well and add a great aesthetic to my PC. Recommend to anyone looking to add more cooling to their rig! ... show more

    • These are awesome
Style: 120mm PWM
Review Image by Jonathan M. Silveira Jonathan M. Silveira
Bought these for a 10-fan build I've just finished. Few things you need to be aware of. These don't have reverse mode, so you'll need to show the back of them if you use them as intake. They do have lights in the back, but they're just thin lines. To me, the back looks better than the front, except for the stickers in the back. You can kind of see the LED spots in the front lights--they're not as uniform. Each fan has standard PWM and ARGB cables. You can daisy-chain the ARGB cables, but not the PWM ones. You'll need a separate splitter cable if you want to plug them all into a single motherboard header. They work perfectly with a Thermalright ARGB Fan HUB Controller and OpenRGB (on Linux anyway--don't know about Windows). Quality and cooling performance are top notch. I attached a picture, but it doesn't do them justice. It looks too dim. The fans look clear in real life without being overly bright. I'm super happy with them and recommend you look into them for your next build. ... show more

    • Fans Are Great - RGB Hub Has Very Limited Instructions
Style: 140mm PWM high speed
The positive - The fans provide great performance. They are quiet. They move a lot of air. The lights look really good on the front and the back. They have an incredibly solid, quality feel to them. The negative - they come with ARGB hub that is almost entirely undocumented. The only thing it says is that you can plug 6 ARGB devices into it, which is the number of ports on it. It doesn't tell you how many LEDS total for the hub or total for each port (because their fans allow daisy chaining - suggesting you can safely use that daisy chaining). After seeing odd lighting results (I'm first time at this), I contacted support. They ONLY said that you can plug 6 total ARGB devices into the hub. They still never clarified individual hub tolerance levels. They seemed to imply that you should only put 1 of their devices into each port. I still have my lighting problems. I have been able to prove that all lights and colors are still functional on the fans, but my motherboard can no longer properly address all of the lights, no matter what I do. I've ordered a Razer Chroma hub, which is well documented, and hope to get better results. Last, the "be quiet!" hub mounts to SSD holes, which is great. BUT, in their own 901 Dark Base case, doing that results in 2 of the 6 ARGB ports being blocked by the case screw that holds the SSD bracket on the case. For all the advertised modularity, there are these weird tradeoffs that surprise you when doing an all "be quiet!" setup. It's a little annoying, considering the full cost of all of it. Spent nearly $500 on case and fans, just to have half the fan lights be wrong color and ports blocked on ARGB hub. ... show more

    • be quiet
Style: 120mm PWM
These case fans really do be quiet. I bought a cheap pack of fans for my first build and can say that these are worth the extra money. They also have just the perfect amount of lighting, not too showy.
