be quiet!Light Wings 140mm PWM High Speed Low Noise Premium ARGB Cooling Fan | 4-Pin | Ideal for Radiators and Heat Sinks | Black | BL075

product is a 4 pin , two cable lighted front type fan. Ruber coated corners, works well with rubber mounts or screwdriver mounting screws. I would purchase again. Ideal for Be Quiet case.

Awesome 140mm fan used to replace top exhaust 120mm nzxt stock fan. Much quieter due not only to larger size but also bequiet brand.BUT make sure you check your motherboard. My asus z390 uses 4-pin 12v RGB headers. these fans require 3-pin 5v ARGB headers and the two are NOT compatible. so you will probably need a compatible hub.Still, great product and I already had bequiet’s dark rock slim cooler so I already knew how awesome their fans were. will probably buy the 3 pack 120mm with hub to replace my other fans.

I ordered the wrong size. I wanted to put the fan in the back of my case but I didn't make sure that a 140mm would fit first. So I had to put it in the top at the back. But it really pulls the hot air out of the case and is very quiet.

I'm using these fans in a push-pull method and they are the front fan of my PC. They are working great my temps have decreased by 5 degrees Celsius. Not only have they called my PC down a bit they look awesome with brightness that lights up the room. Very happy with this pair of fans.

Works as front case fans currently, works pretty good and keeps my system cool enough, and sticks with the theme of my system with RGB (little more stealthy RGB with my build). Wouldn't recommend it for the price tho, they're a bit pricey compared to 120mm alternatives of the same speed and RGB design, but that's what u pay for the quality u get in return

Gd color diffusion....works well but a tad noisy.

Upgraded my PC a few weeks ago, and I decided I wanted RGB fans. The be quiet! Light Wings was the perfect choice. Good acoustics, performance, and just a dash of RGB without being obnoxious. I bought a variety of Light Wings, including the 140mm PWM high-speeds, 120mm PWM high-speeds, and an 120mm PWM "regular speed". They're all great. Silent, good airflow, nice RGB. Except...The 140mm PWMs had strangely bad QA? I bought 2 to populate the front of my case. 1 of them was perfect. The other made a clicking/ticking noise, which was especially annoying at 50-60% max fan speed. Returned it for a replacement, which also had a clicking noise. Barely perceptible but it was there. Unsatisfied, I got another return, but this one ALSO had the same problem, but worse. I didn't want to get flagged for too many returns, so I kept the 2nd fan.I dunno if this is just a bad batch, or if they're all getting banged up during shipping. Honestly it doesn't matter. While these fans are great when they're perfect, I can't justify giving these fans a 5/5 star review with the experience I've had.EDIT: After about a week and a half of use, the clicking has grown louder to the point that it's audible at idle. Very disappointing. I will be swapping this fan for another replacement, though I'm not looking forward to playing another round of roulette.

The fans are very good but I had to replace them several times due to a rattling noises they started to make after a period of time.
