be quiet!Silent Wings Pro 4 120mm PWM 3000 RPM Premium Low Noise Cooling Fan | 4-Pin | BL098

no vibration level, very silent.

These are so quiet, and run great. Keeps everything cool. Had to look down to see if they were on.

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.

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

It's really quiet at lower speeds, which does actually push a lot of air anyway. Higher speeds it is loud and has a higher pitched moan/whine, even when not mounted, so it's not like an obstruction that's interfering. I'd probably buy again anyway, because it is effective. I just don't run it high any more.

Solid fans. Really good. Buy them.
