Great little fans 3/27/2020 12:16:52 PM

Pros: - Nice, conservative aesthetic
- Lives up to the brand name
- Long, sleeved cabling
- Interchangeable mounts (silent, and extra silent options)

Cons: - None so far

Overall Review: If you're looking to improve airflow to or from your case, you really can't go wrong with this fan. Installation is easy, sound is almost nonexistent, and the build quality is second to none.

Very quiet 3/26/2020 8:15:55 AM

Pros: Running AMD Ryzen 9 3900x 12 core - with a stock cooler. Great fan helping keep my CPU & GPU Cool. Also very quiet. For the price very worth it. I grabbed some 120s for my case but if your case can fit the 140s would be worth it.

Cons: None.

Overall Review: Great product

Quietest fans on the market 1/17/2020 12:04:25 PM

Pros: Very quiet
Great air flow
Great control
Nice, clean look

Cons: Can not think of any

Overall Review: I bought a Corsair case that came with two fans last year. They are garbage so I replaced them with be quiet! Silent Wings 3 hi flow PWM fans. What a difference in sound levels. be quiet! makes a great fan. They were much quieter than the Corsair fans and better than the Cooler Master fans that came with my AIO. This year, I build another machine and bought two more be quiet SW3 fans. I am a convert. Worth every penny and highly recommend. be quiet! has earned another loyal client.

Very quiet at beginning. 12/26/2019 10:39:56 PM

Pros: At beginning about two months until now they run ok in my Be Quiet case, extremely quiet. High quality overall

Cons: My rear fan is becoming annoyingly noisy - crazy noises like almost like beeping and squeegeeing - looks like it happens when it is starting up and that happens very often. I don't know what to do, just now again happened like dial up modem sound...
Im using them a little bit over two months now -

Overall Review: If manufacturer would replace the bad one I would be happy customer and would upgrade to 5 stars.. The other two runs perfectly.

G.P.

possibly dying after less than a year 12/7/2019 9:07:28 AM

Pros: - Silent. The only sounds I hear from it are ones that I don't want to hear see cons below
- Moves plenty of air
- The lack of LEDs is a nice option for those of us who don't want our cases lit up like a Christmas tree
- Drops in perfectly to my Cooler Master Evo for a quieter replacement of the stock fan

Cons: - Sounds like the bearing may be going out already.
- About once a week, I hear it struggling and squealing as if it needs oil. Lasts a few minutes, then either quits or gets going
- Always squeaks while spinning down after power off

Overall Review: TL;DNR:
this fan was GREAT when it ran.
after about 5 mos. It's showing symptoms of failure,
BUT
It could just as easily be caused by my Mobo.
I will update this review upon MB replacement

I got this to tone down my system that had a case which was all mesh, and had a lot of noise.
It Ran perfectly for about a month, then the power-down squealing started. But I didn't really mind, as quite frankly, it was a nice confirmation that all my hardware was off (I don't have a lot of lights in my case). in the last two months however, it's began struggling during normal operation. earlier today, it was squealing, and when I looked in there, it wasn't spinning at full speed. A quick flick of the fins got it back where it needed to be, but it's not the first time, it's happened either.

THAT SAID, THERE'S ONE MORE VARIABLE:

My Motherboard is ALSO having problems, and needs to be replaced. It's possible, that this is a power distribution problem, and I will update my review when I get my new system built

Overrated 11/4/2019 8:34:33 PM

Pros: - Quiet, but only below 900rpm.
- Black, so it goes with everything else.
- Two different mounting options.
- Rubber isolators built into the frame (for the screw mounting configuration, that is).

Cons: - Starts to sound like a wasp or beehive at higher than 900rpm.
- Rubber isolators fall off very easily - use washers or be careful when mounting with screws that come into direct contact with them.
- "Low noise" rubber isolator mounts (the ones that attach with the plastic pins) make no difference with the noise level and IMO aren't worth the hassle.
- Surprisingly high rate of DOAs and problematic PWM drives - be prepared to RMA one for every five or so.
- None of them seem to operate in plain DC mode, even though any other PWM fan can do this...

Overall Review: Use these if your case came with such lousy fans that a large fly buzzing around your ears would be a more pleasant experience.

Great fans , very quiet. 10/30/2019 10:44:19 AM

Pros: Have good static pressure and high rpm range, using them on a couple of radiators and at any speed the wind noise is all that is heard .
Comes with different corners for mounting to a radiator or as a case fan , both featuring excellent vibration dampening.
The plastic pin mechanisms and corresponding corners allow tool-less installation when used as case fans.
Sleek black aesthetics.

Cons: Of course as a consumer you would always prefer to pay less money , but for the level of performance the price is more than fair.

Overall Review: They have a better price to performance ratio than certain beige and brown fans many recommend which i was also considering . While the new noctua A series fans have slightly better performance to noise ratio , the higher rpm range of the be quiets makes their peak performance extremely close , just at a slightly higher noise level. That said the 50% price premium for the noctua's is simply not worth it for a barely perceptible noise decrease especially when buying 4+ fans such as i did.

nice under the right circumstances.. 10/14/2019 1:34:43 AM

Pros: at other than full speed these are pretty darn quiet.. but turn three of them on in the front of a corsair 900d and oh boy, you'll know they are there.. i'm pushing against a lot of drive cages though with these.. i've had other be quiet models and have no issues with them..

Cons: you will hear these if you turn them on full speed.. unlike another commentator, i think i'll be going to noctua and put up with the color scheme; can't really see the fans anyway in my case..

Overall Review: see above
