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 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 optimization for maximum airflow, Light Wings 140mm PWM is the right choice for any case configuration that demands high cooling performance. Its seven airflow-optimized fan blades not only reduce noise-generating turbulences but also ensure Light Wings 140mm PWM provides the performance that is needed, even in demanding configurations.
- A highly optimized impeller achieves the silent operation be quiet! is famous for. With a noise level of 23.3dB(A) at maximum fan speed, it proves that instead of being a replacement the lighting is an addon to very silent and powerful operation. All features combine to make Light Wings 140mm PWM 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.
- Developed and Designed in Germany

### ⭐⭐⭐⭐⭐ 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.
