be quiet! Silent Wings Pro 4 120mm PWM - Fan Noise 

I like this fan, when it starts spinning it reduces the overall noise in the room. Absorbs decibels!

Please do some air and aio coolers! Very interested in how the various aio pumps sound, and what an air cooler like thermalright pa sounds like. Your channel is the only one I've come across that covers the acoustics of fans.

Glad you're back! I think the blade geometry is pretty close to the MSI P12, of course with the grooves and a bigger fillet at the bottom edge. I wish they would just give it a proper flange at the exhaust. Round intake is great for getting rid of eddy turbulence but the exhaust should have a flange to properly seal. The 3 big nidec fans on the 2019 mac pro do this very well. To me the SW4 Pro seems kinda overpriced, I'd just get a Phanteks T30. Non pro however should be a good option at 21€ street price in EU. Definitely big improvement over the SW3.

There's some background buzzing, and it's not the fan.

this made me instantly buy 2 for my mini itx

Very good for high flow fan... More air noise than engine / bearing noise

That is really Silent Fan ! at 1681 rpm, I have to max out volume to hear the noise and it is still not that loud. Amazing !

Thank you, channel without words, but very useful. Instead of a thousand words - record the sound.)

Can u tell that software to change the speed of fan you use in this video! Tks so much

MB makers should create apps that link the Windows sound output volume to the fan control, so you can go "turbo" on the fans above a specified threshhold if the game volume levels and temps warrant...or link to Microsoft Flight Simulator and slave the fan speed to the jet engine turbine setting of the plane I am flying. 😛

Looks like it would make for a good upgrade for the Dark Rock Slim and would make it competitive to any 120mm cooler out there, especially against the NHU-12s and the NHU-12A.

Do you think the 140mm will have the same results please? thank you

while they might seem loud, at max speed they are actually fairly quiet (At a distance)

very nice noise levels. Looking into getting silent wings 4 140. There’s some resonances at around 1200 rpm and 1680 rpm and 2580

I'm disappointed that none of the fan took off or exploded during any of your testing.

Thx!

It does resonate at certain frequencies, but only above 1300 RPM.

Can u do the Cooler Master Mobius 120?

Very nice. At 1200rpm, it’s pleasant! Is that switch on the back for adjusting max RPM???

hummm,this is a really nice fan

Hi, thanks for awesome review. Can we expect the same with non-pro High-speed model? Is there any difference besides higher max RPM and extra corner mounts ?

What would you say currently are the quietest, best performing fans for a heatsink? Looking for maybe your top 3 suggestions. My AP201 case is the all-mesh version right next to me on my desk, so noise is key. I have some Phanteks M25-120s, and they perform well, but make a faint buzzing/grinding noise. Do you think that's something that will go away with time? Thanks for your testing.

it's quieter than my 1080 Ti FE

Was this done using PWM or DC control? The SW4 Pro 120s supposedly start at 800rpm using PWM, which I find a little to high.

Thanks for the video, I bought that fan Be quiet! Pure wings2 140mm But I want to use it for my mini camper There is 4 wire one + one - and two F , I tried different ways doesn’t work Please tell me how to install it , thanks

whoah! that is one silent fan!!!!

i cant hear it over the sound of my gaming laptop fans idling

please the non-pro silent wings 4 140mm pwm

hope to test Montech METAL 120mm PWM

Bro, may I ask to compare between ML120 Elite vs Be quiet silent 4 pro for the radiator. Which one do you think is the best? thank you

Is this a good fan for an upgrade from noctua nf-f12 or i should keep my noctua fan?

Quietest under 1000 rpm I've heard on your channel. Listened in iem. I'm tired of the shuffling, hissing sound at low speeds in the gentle typhoon.

i will strap 3 of those on my rtx 4080 later. this year

It's been 6 months are you going to make new video? I really like your context just suncribed but ran out of videos to watch lol so just asking for future reference

What's that electrical noise throughout the video?

What is the current quietest fan available that would work with a 13900k and 4090? Im tired of noise! :(((

on PWM i'm getting coil whine on 140mm silent wings 4 pro, on dc there is no coil whine. Is it product problem or all sw4 have it ?

Please demo their 140 SWPro model

If you watch closely at 2:13 the gap between the fan blades and frame grow as the fan winds down. The material BeQuiet chose is not as good as Noctua's LCP Sterrox, unfortunately.

Is this the quietest 120mm fan at high RPM?

"I would still expect the Noctua to have the edge in acoustic quality and noise-normalised performance due to the LCP blade material." In my experience, it really doesn't. This fan can run at least 200 RPM higher while being quieter. The Noctua A12x25, which is one of my favorite fans, is somehow noticeably louder, and is honestly ancient tech by now. That LCP stuff is overrated, but I wouldn't mind them putting it on the SW5. I put three of these as intakes in my PC and one SWP4 140mm as exhaust. Delivers the best airflow my PC has ever had and is quiet while doing so. I'd say this is the best fan on the market rn. Cools a 4090 just fine, my previous SW3 were not capable of it. Also, Noctua really needs to start packing pushpin / anti-vibration mounts with their fans. The pushpin mounts are a BIG reason why I buy the Silent Wings every time. Reduces vibration a lot and are much easier to deal with than the usual long AV mounts that Noctua provides with their regular fans but not with Chromax fans for some dumb reason.

0:59 is that a whining noise? It briefly reappears again at 1600rpm.

is this moree quiet than a Noctua NF-A12x25 PWM at 1000rpm?

I am curious about how the bearing part’s size (middle of the fan) relates to fan’s performance. It definitely affects the airflow area, and from my guess maybe the stability of fan blades (e.g. away from wobbling). How do you guys think? Plz leave a comment

I heard they are still louder then ver 3.

Ah so this fan is definitely better than the noctua I commented previously on xD right?

Test the Mobius 120 OC too.

Why you are not making new video?😢

This sounds like the end of the world 😂

Damm

THis or redux 1700RPM?

i love this fan. May i buy this fan and put at scythe fuma 2

anyone use this to cool their ice river ks0?

a12x25 vs ph-f120T30 vs silent wings pro4. 🤔

It's quiet, probably the most quiet, but for some reason i don't love the sound. I don't know what it is, it's subjective. "Sounds" kinda cheap and weak, almost cute, compared to the A12x25's. Dunno if it's cos it's a higher pitch or something. It's the kind of sound that when it's above 1500rpm it kinda stresses you out that your computer's working too hard. This has been my TED talk thank you

🤔 pro 4 be quiet - didn't get the memo on being quiet .

Шумный немного но и обороты высокие

At max RPM, my headset took off the land

The annoying noise this fan makes at 1300rpm and 1800rpm makes it obsolete when you want a silent fan. The T30 seems like it's the only good fan that doesn't make that type of sound when ramping the fan speed up or when it slows down.

Too much ambient noise! I want to hear the fan, not hum of speakers

What is this pryyyyy😅
