## Description

Product Description FOR RADIATORS AND HEATSINKS With a remarkably high air pressure of up to 2.3mm/H2O, Light Wings 140mm PWM high-speed is the best choice for water-cooled and air-cooled systems alike. QUIET OPERATION A highly optimized impeller achieves the silent operation be quiet! is famous for. With a noise level of 31dB(A) at maximum fan speed, it proves that instead of being a replacement the lighting is an addon to silent and very powerful operation. VARIABLE FAN SPEED FUNCTION Pulse Width Modulation (PWM) allows compatible 4-pin controllers, including those built into many motherboards, to intelligently vary the speed and thus the noise level of the fan.

Review: Great fans, good deal - They look great, they are super quiet, the hubs works great.. and I think it's a good deal package, top quality
Review: These are amazing! - 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

## Features

- Light Wings 140mm PWM high-speed offers ARGB lighting at the front and rear. The subtly lit ring at the back combined with the bright one at the front make for a magnificent appearance from every angle. 20 ARGB LEDs give you many opportunities to individualize your PC build.
- With a remarkably high air pressure of up to 2.3mm/H2O, Light Wings 140mm PWM high-speed is the best choice for water-cooled and air-cooled systems alike. The 9 airflow-optimized fan blades provide enough air pressure to make this fan perfect, even in demanding configurations.
- A highly optimized impeller achieves the silent operation be quiet! is famous for. With a noise level of 31dB(A) at maximum fan speed, it proves that instead of being a replacement the lighting is an addon to silent and very powerful operation. All features combine to make Light Wings 140mm PWM high-speed the fan of choice for silent show cases and gaming systems alike.
- Pulse Width Modulation (PWM) allows compatible 4-pin controllers, including those built into many motherboards, to intelligently vary the speed and thus the noise level of the fan. With PWM the system can ramp up the cooling when it’s needed, or operate in maximum quiet mode when it’s not.

### ⭐⭐⭐⭐⭐ "Be Quiet" and they are
*by G***E on 21 November 2025*

these are amazing fans, the really are quiet and my god do they move some air. they're simple to install and well worth their rather high price. they look really good too. my only gripe is that i would like them to become available in packs of 3 with the reverse blades so i could have the nice side in on all of them .. see picture. i would recommend be quiet fans to anybody wanting to have lots of airflow.
