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

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.

Great 120mm fan choice, quite when at lower RPMs, and move a lot of air when turned up. I exclusively use Be quiet fans and have not had a failure yet. Thick material on the fan and blades, quality look and feel, mounting hardware is quality and the power cables look great.

I’ve tried a lot of high-end fans from Noctua, Phanteks, Lian Li, Arctic, etc, and I was really surprised with how good the SWP 4’s are. In some ways IMO they are one of the best 140mm fans on the market, if not thee best. Let me explain why. In terms of brands the two best fans I’ve ever used are the Noctua NF-A12 G2’S and the Phanteks T30. Like the SWP 4’s they both strike the perfect balance between high airflow and silent operation. HOWEVER, the reason why I ended up going with the SWP 4’s is because (1) the Noctua G2’s only come in their distinctive yet fugly brown color, and (2) Phanteks still hasn’t released a 140mm version of the T30. So essentially, if you need black 140mm fans that are both high performing and silent, the SWP 4’s are currently the best option on the market today. They’re also a very attractive fan with high quality cabling so if you’re into aesthetic building like I am they look great on a radiator. In terms of how quiet they are, I have them in my SFF PC which sits directly on my work desk and while idle my PC is completely silent. But even at higher RPM my PC sounds similar to an air purifier - no vibrations, motor sounds, droning, etc, just a pleasant and subtle rush of air akin to white noise. Overall I definitely recommend these fans especially if you need 140mm.

I have purchased about 3-4 of these so far, and my case is full of them. They run great, and are very cheap for their performance. I can easily adjust the fan speed using the BIOS in my motherboard, and their black color is very sleek for my case. They have lasted me 3 years so far, and are still going strong. The airflow is also nice.

The best fans I've ever owned. They are quiet quiet. Really nice. I have an all black set up and they work so dang well. Mine are set at max speed at all times and they dont make any noise. The black is sold and they wear easy as all heck to install. Love them.

Very quiet, non audible at low rpms while gaming. Using these around 600 rpms and keeps my pc cool. They move air efficiently, great in blackout low rbg builds. Worth price.

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.

Four of these were purchased to replace the original 2-wire 12VDC fans in an old Cooler Master Cosmos 1000 case. They are well made and come with two types of corner mounts, one with that uses screws and one that uses pins. They're run from two PWM fan headers on a new motherboard, one header drives three fans through a 3-way splitter cable (purchased separately), the other header drives the fourth fan. They're working perfectly and are inaudible in normal operation.

The instructions manual is hidden under the fan package , come with 2 sizes of the mounting and the screws in the accessories box. Depend on which mounting you prefer , installation was very easy and quiet

Está increíble. Tiene excelentes velocidades y no hace ni un poco de ruido. Totalmente silencioso incluso a su máxima capacidad. Recomendado totalmente. Ojalá haya en el futuro uno de la misma marca disponible en 80mm

Exchanged my stock EK Nucleus AIO fans. Didn't do much for the temps or noise in my original push config in a Meshlicious case. Switched to a pull config (fans outside the case, and the temps and noise is amazing now! Next time I will test Noctua instead tho.

Below about 25% it is essentially silent, and still moves quite a lot of air. Even at 50% its still quiet. Yes, its noisy at 100%.... but all fans are, this one is not as noisy as any other fan I've ever used at any speed.

Dopo aver provato le be quiet! Silent Wings Pro 4 140mm nella stessa build e averne apprezzato la qualità, ho deciso di acquistare anche queste da 120mm, per montarle sull’AIO. Uso il mio PC esclusivamente per il gaming, e cercavo delle ventole che non solo fossero silenziose, ma che fossero anche in grado di gestire le alte temperature che arrivano quando spingo il sistema al limite. Be quiet! mi ha sempre impressionato, e con queste ventole non sono rimasto deluso. 🔇 Silenziosità La prima cosa che mi viene in mente quando penso a queste ventole è quanto siano silenziose, e questo è stato uno dei motivi principali per cui le ho scelte. Sì, è vero che girano fino a 3000 rpm, e a quella velocità si cominciano a sentire, ma il rumore che producono non è mai fastidioso. È un rumore “da ventola”, che ti fa capire che stanno lavorando, ma non disturba in nessun modo, nemmeno nelle sessioni più lunghe di gaming. Per me, che gioco spesso per ore, la tranquillità di non sentire un rumore fastidioso è fondamentale. E anche quando gioco con la musica in sottofondo, nemmeno me ne accorgo. 🌬 Prestazioni di Raffreddamento Quello che mi ha veramente colpito è che, nonostante la silenziosità, queste ventole fanno il loro lavoro alla grande. Il mio sistema non si surriscalda mai, nemmeno quando spingo il PC durante le sessioni di gioco più intense. Ho provato a stressarlo un po’, e posso dire che il raffreddamento è stato impeccabile. Le temperature sono sempre rimaste basse, e questo mi dà una grande tranquillità. Non devo più preoccuparmi del calore che può accumularsi durante le maratone di gaming. 🛠 Costruzione e Qualità A livello di costruzione, queste ventole sono proprio come me le aspettavo: solide, ben fatte, con una qualità che si sente appena le prendi in mano. Ho sempre avuto una certa fiducia nel marchio Be quiet!, e ogni volta che compro qualcosa di loro, è come se non potessero deludermi. Le ventole si montano facilmente e sono molto silenziose, anche durante il montaggio. La sensazione di qualità si percepisce subito, e mi fa pensare che, anche dopo mesi o anni di utilizzo, non avranno mai problemi. ⚡ Efficienza Energetica Un altro aspetto che mi ha convinto è l’efficienza energetica. So che a 3000 rpm le ventole lavorano al massimo, ma nonostante la potenza, il consumo energetico è contenuto. Questo mi ha fatto riflettere sul fatto che, pur avendo un sistema potente e performante, riesco comunque a mantenere un buon bilanciamento con il consumo di energia. Non è una cosa che capita sempre con ventole così potenti. 🔧 Compatibilità Essendo parte della stessa build delle 140mm, queste ventole si sono integrate perfettamente nel mio sistema. Non ho avuto alcun tipo di problema durante l’installazione, e tutto è andato liscio come l’olio. È stato bello vedere il sistema diventare più coerente con ventole della stessa serie, ma di dimensioni diverse. Si sono adattate perfettamente al mio AIO, senza dover fare alcun aggiustamento. 🕰 Longevità Essendo le 140mm che ho già montato nella mia build ancora in perfetta forma, sono abbastanza sicuro che queste 120mm non mi daranno problemi nel lungo periodo. Il materiale è di qualità, e tutto sembra fatto per durare. Non vedo l’ora di vedere come si comporteranno nel tempo, ma sono piuttosto tranquillo a riguardo. 💰 Rapporto Qualità-Prezzo Ok, non sono le ventole più economiche che troverai, ma sinceramente, il prezzo è giustificato dalla qualità. Per come sono costruite, per quanto sono silenziose e per le prestazioni che offrono, non mi dispiace affatto l’investimento. Quando si tratta di raffreddamento, preferisco spendere un po’ di più, sapendo che avrò un prodotto che durerà a lungo e che farà il suo lavoro in modo impeccabile. Conclusioni Le be quiet! Silent Wings Pro 4 120mm sono davvero una scelta azzeccata per chi cerca prestazioni elevate senza compromettere la silenziosità. Dopo aver provato le 140mm, non avevo dubbi che queste 120mm non mi avrebbero deluso, e posso confermare che è così. Il mio PC è sempre fresco e silenzioso, anche nelle situazioni più stressanti. Se come me usi il PC per il gaming e non vuoi sentire rumori fastidiosi, queste ventole sono quello che ti serve. Consigliatissime!
