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.

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!~
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 :)

Good balance of aesthetics and performance.
I'm generally iffy on RGB lighting in computers, but do like it as an accent in a few places. The light ring style makes an excellent accent, especially when contrasted against the angular nature of most PC components. They provide overall less lighting in total unless you set them to just straight white, so your case doesn't look fully lit, keeping the contrast between light and dark, emphasizing the rings themselves, which I find very attractive. When I do run white, I set them to about 35% brightness. They also tend a little blue, so you may need to adjust the blue channel down a bit more than green and red if you want a pure white, but most RGB components have similar issues. I'm terms of performance, trading the few millimeters at the outside edge of the fan for the light ring probably costs a bit of airflow performance, but these seem competitive with even most non-RGB fans. They won't match BeQuiet's own Silent Wings Pro 4, Noctua's NF-A12, or Phanteks' T30, but they are at on par with many decent fans. The noise isn't super quiet when you get to the high RPMs, but it's a very unobtrusive pitch that's quickly drowned out by the audio you *want* to hear from your PC.

Awesome fans : ended up buying more! 🔥
These fans are seriously great. Super quiet, nice airflow, and the RGB looks clean without being over the top. Great value for the price too. I was so happy with the first one that I ordered 3 more! 💨💡 If you want performance and aesthetics without breaking the bank, these are a solid pick. Totally recommend.

Fans Are Great - RGB Hub Has Very Limited Instructions
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.

Would buy again if any of these fans fail.
Best fans to fit my setup, and provide the right cooling for my build and case. Took a while to research which fans I needed, even at high RPM's they are still quiet. The cables are long enough to reach my hubs and that is all that matters. Colors are vibrant and was a good value for the quantity and quality. They are very reliable and easy to install.

Sessizlik
Koruyucu tedbirler alınarak orjinal kutusunda ve hızlıca kargolandı. 15 yaşında oğlum desteğimiz ile montajını yaptı. Sonunda sessiz çalışan bir bilgisayarı olduğu için çok mutlu.

Leise, stark und sieht richtig gut aus
Die be quiet! Light Wings 120mm PWM high-speed Lüfter haben mich echt überzeugt. Ich hab sie in mein Setup eingebaut, und schon beim ersten Start merkt man: richtig leise, selbst bei höherer Drehzahl. Die Kühlleistung ist top – die Temperaturen sind deutlich runtergegangen, ohne dass der PC wie ein Staubsauger klingt. Optisch sind sie auch ein Highlight. Das RGB sieht super sauber und hochwertig aus, nicht so übertrieben wie bei manchen anderen Marken. Anschluss und Steuerung liefen problemlos, alles ließ sich easy im BIOS oder über die Software einstellen. Fazit: Leise, effizient, stylisch – genau das, was man von be quiet! erwartet. Für mich aktuell die besten 120er Lüfter in der Preisklasse.
