be quiet!Silent Wings 4 120mm PWM High Speed 2500 RPM Premium Low Noise Cooling Fan | 4-Pin | BL094

Exactly as advertised. These made my desktop more quiet than my wife's laptop. I'm very in impressed. Nice job!

Great fan, moves a lot of air with not a lot of noise.

Would rate 10/10 if possible. Mounted to a kraken x63, keeps the coolant under 30°C and 5900x that it's mounted to under 74°C with an ambient if 22°C. Can be somewhat noisy at high speeds, but nothing a noise cancelling headset cant fix

Solid fans. Really good. Buy them.

I was looking to get the best low-noise but high performance fan for the single output of my case to balance with the 4 low-noise fans I had running for air intake. Originally I had Fractal Design Dynamic GP14 fan that came with the case but I swapped that to be an additional input when I upgraded to a higher powered Corsair ML140 Pro. With the Corsair fan performance was decent but I found it seemed to get a bit noisy at moderate speeds.Realistically, my cooling setup was always more than adequate, I didn't have any temperature issues whatsoever, but I am a bit of a nerd for good air cooling and just like upgrading something once in a while and it seemed like there was room for improvement here.I had the corsair for several years but I would occasionally do research on fans or watch the latest reviews and comparisons of fans on youtube. Eventually the time felt right that I felt like spending the money and that there were some good options to upgrade to. This fan has been a definite improvement capable of moving more air at lower sound levels. I also like that it has the headroom to push to even higher speeds than I need with my current setup just in case I ever feel like it or was trying to max my performance having fun overclocking and benchmarking.I didn't bother to do any recorded tests of my temps but my subjective experience has been that I am very happy with the performance as I created a fan curve for it that gives me what I want airflow wise and my computer remains quieter than it did before. I also stepped away from having my computer with so many LED lights so the transition to a fan without lights worked for me. A few months ago I made significant upgrades to my processor and my video card and this still handles everything I can throw at it with ease and quietness. I have been super happy with the performance of this fan and will definitely have them in mind next time I am building a system.

extremely good quality quiet and would recommend to anyone looking for a performance fan. The best part is the switch allows you to adjust the pressure and or air flow in the case relatively easy. I will use this for every case I have in the future be quiet you've earned a lifetime user thank you. VERY HARD TO GET

Splurged on four of these to replace a disappointing set of Arctic P14 Max, which were themselves a replacement for my case's Fractal GP-14s, one of which developed a rattle. I wanted to replace them all to keep the aesthetic consistent.Build quality and quality control are excellent. All four are identically silent at low speeds, only becoming noticeable with low background noise above around 650 RPM (30% PWM). There's no rattling or buzzing or anything, only a very quiet high frequency whine from the motor which I can only hear when I take a fan out of the case and put it up to my ear at low RPM. Huge improvement over my poor luck with the Arctic 5-pack. Quieter than the Fractals, too, but not particularly noticeable in normal usage.They spin down completely under around 200 RPM (10% PWM). They're practically silent when they spin back up, too, unlike the awful ratcheting sound I experienced when the Arctic P14 Maxes kicked in. This is how a "Zero RPM" feature should work. I have them going at 200 RPM baseline anyway because why not, they're completely inaudible.They push a lot of air, too. Not as much as a P14 Max at high speed due to the obvious difference in RPM, but it's more than you'll realistically need anyway. Thanks to the much reduced noise level, you can safely bump your fan curves up a bit to offset the lower RPM without sacrificing peace and quiet. As far as I can tell, they push more air than the Fractals, and at lower volume, but not enough that I'd recommend spending this much to replace quality fans that come included with a mid-high end case.That's really the only problem I have with them: the price. I wouldn't recommend anyone do what I did and spend $23 (or more) to replace several perfectly good fans with, admittedly better, aftermarket ones. Of all the things to upgrade in a system, case fans should be pretty low on the priority list. But if you're replacing a bad one, I'd absolutely pay the extra premium for something that, based on my experience, performs better where it counts (and is a lot more likely to work properly in the first place).You get some interesting accessories. Each fan comes with two sets of removeable corner pieces, one set of thinner, flexible rubber ones which are installed by default, and one set of standard hard plastic ones. The plastic ones are secured by screws like normal, but the rubber ones feature toolless installation with included plastic push pins. I tried the rubber ones and they work just fine for my use, though the toolless installation isn't really any easier than just grabbing a screwdriver. I don't know if they're contributing any reduction in vibrational noise but hey, it's an option.I want to mention the aesthetics, too. Man, be quiet! has my favorite fan aesthetic going for it. The ridges on the blades are subtly visible while the fan spins, giving the impression that my case is full of vinyl records. Pretty cool. The cables are also sleeved, which looks nice but does make them a little less flexible for cable management.tl;dr Great and consistent quality and performance, but IMO too expensive for a full system overhaul. Highly recommended to replace 1 or 2 busted fans.

I bought these to use with my 360 mm AIO radiator in a rackmount gaming PC and wanted the high static pressure these offered along with quiet performance at low rpms. These have delivered by lowering my CPU temps and increasing my 3dmark benchmark scores
