be quiet! Light Wings 140mm PWM high-speed fan, ARGB lighting, multiple colors and modes, silence-optimized fan blades, high air pressure, low noise-generating turbulences, long life rifle-bearing

They look great, they are super quiet, the hubs works great.. and I think it's a good deal package, top quality

The quality of these fans is excellent, I love the look of them with the halo rgb rings. They are also so much quieter and premium than the fans that came with my case. Well worth the upgrade.

1.) Noise - Does just as advertised. The noise is barely noticeable. I have mine with a fan curve starting at 60% and at idle/low loads you can barely hear them. At full blast, max RPM, the noise is noticeable but I believe it is mostly due to my fans pushing air through the fins of my radiator. 2.) Lighting / connectivity - Very vibrant and strong LEDs. They come with a hub and they connect to the ARGB header on the motherboard. I control them through Armoury Crate (Asus). Very simple sinc up and it matches the colours perfectly between my MB and GPU 3.) Cooling - I had cooler master fans that developed a rattle so I replaced them with these. The Cooler Master fans held my pc at 39-41 Celsius under no load, up to 75 under load. With these, it's 31-32 degrees no load and 60-65 under load Really really satisfied with these I did add 3* for easy to install as it is not very easy to replace fans within a PC

I love this company - fantastic build quality and work superbly in my bequiet! pure Base 500 FX case. Fans are inaudible at all but the highest RPM and look great.

Really nice reverse fans, easy to install they look great

Good fans but bit overpriced (£28-ish).

I bought these for the brand and they do what I expected.

These be quiet 140mm fans are just the business. They are so very quite and were very easy to install in my Phanteks desktop case. I would most definitely buy again if I needed more.
