## Description

be quiet! Light Wings | 140mm PWM high-speed Boitier PC Ventilateur 14 cm Noir 1 pièce(s)

Review: Definitely very quiet - These are excellent fans of a very good quality, they look really good shame they dont plug together to save the rats nest of wiring .. 2 wires each fan. They are simple to install, give a massive amount of airflow so cooling high end parts isnt a problem, the colors are nice and vibrant, i consider them well worth their price and would livevthe 3 pack to become available with reverse blades so i could have all of mine with the nice side facing inwards. Would recommend 100 percent
Review: Purchased these as a replacement for the CoolerMaster fans I had - My cooler master fans which were ok rated and decently reviewed basically gave out and started rattling within 3 months of use. Soooo, considering I did not really save any expense on the rest of the build, I decided to get one of the best, the Lightwings They look good, absolutely champ performance for the cooling. I am using a 5800X3D with a 360 mm rad water cooling from Asus Rog I put the high performance ones on the radiator, temps dropped about 6-7 degrees when idle (37 degrees celsius) compared to the old ones and I put the regular version for airflow within the case. Temps dropped about 10 degrees compared to Coolermaster when under load Very satisfied with the purchase, quiet, high performance, not much else to say

## 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.

### ⭐⭐⭐⭐⭐ My favourite fans
*by A***R on 13 January 2026*

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.
