be quiet! Silent Wings 4 120mm PWM High-Speed Fan, Fluid-Dynamic Bearing

I’m running five Silent Wings 4 fans in my system, three 140mm front intakes, two 140mm top intakes, and a 120mm rear exhaust. Airflow is excellent and thermals remain consistently strong even under sustained load. The fans maintain good static pressure and stay impressively quiet at higher RPMs. Build quality is solid, and PWM control works smoothly. Highly recommended for anyone aiming for strong airflow without excessive noise. Highly recommend!

one of the best fans on the market

Excellent replacement for my PC case, 4 pin connection so its speed is regulated by the motherboard , and its very quiet Good investment.

Strong, reliable, well built - very quiet

Great fan. Very quiet, good design, easy to fit. Great price.

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.

I recently bought the Corsair RS120 (set of three), and they did not meet expectation (I could hear them over my noise cancelling headphones), I could tune with the fan curve, but even then they still fell below expectation. They're now boxed up in the cupboard as a backup. I already had a beQuiet CPU sink/fan and it's basically silent (actually silent, not just a marketing gimmick) so I thought I'd try the beQuiet Silent Wings 4 for my front fans. Needless to say they're pricey, but.... very very quiet - so I'm very happy. At highest RPM's you can hear them whirring, but for standard PC use and even gaming, they're silent or near silent. Even when you can hear it, the sounds is restrained, no hair-dryer here... If you value peace and quiet, these are the ones to go for.

Decent but not what I asked for, I needed a fan same size as my stock fan and got one twice the size, it works decently but does the polar opposite of what it's said to do. By now my pc would've settled down but now it's rattling and sounds like a leaf blower while maintaining a consistent 74°c which is a improvement from the standard 80°c, I'm not happy it's loud even with the rubber washers placed on it not to mention reorganising the whole cooling system so I'd say this is the first and last time I buy this product from them again. I'm gonna continue trying to make it less loud and if I can't I'll just have to settle with the stock fan until I have a valid reason to install them in a newer pc..

These are quiet compared to my ten year old but unused 120mm Corsair fans. the tighter tolerances of the fan blades to the shroud move plenty of air at slower speeds. The black is more matte than most black fans and the connection cord is better integrated than other fans Ihave bought in the past.

RAVEN RV03というPCケースのTOP排気、リア吸気の120mmファンとして購入。 本当に静か…高負荷かでもそんなに五月蠅くなく、通常時はほぼ無音と感じる。 でもしっかりと機能しています。

Ventilateur hyper silencieux et très efficace ! Je recommande les yeux fermés malgré le prix assez premium, le confort d’utilisation derrière en vaut largement la chandelle !

Le Be Quiet! Silent Wings 4 High Speed sono un prodotto che trasmette qualità già dal primo momento, persino dal peso: solide e ben costruite. Le ventole sono straordinariamente silenziose fino all'80% della potenza, praticamente inudibili, e offrono prestazioni che non lasciano spazio a dubbi. Nel mio vecchio PC avevo già montato le Silent Wings 3, di cui ero entusiasta, ma queste sono un netto passo avanti. Il design delle pale e del telaio è stato ulteriormente ottimizzato per migliorare sia il flusso d’aria che la pressione statica, rendendole ideali per qualsiasi configurazione, dal raffreddamento ad aria ai radiatori per sistemi a liquido. Punti di forza: Silenziosità estrema: anche a velocità elevate, il rumore è contenuto e mai fastidioso. Materiali premium: il design e la costruzione delle ventole sono di altissimo livello, e i gommini anti-vibrazione fanno la differenza in termini di stabilità e silenzio. Versatilità: perfette sia per case che per radiatori, grazie all’ottima pressione statica. Durata: il motore FDB (Fluid Dynamic Bearing) garantisce affidabilità e longevità, un aspetto fondamentale per chi vuole un sistema silenzioso e duraturo. Considerazioni personali: Ho installato queste ventole in una configurazione di raffreddamento ad aria, e il miglioramento è stato immediatamente evidente sia in termini di temperatura che di rumorosità. Be Quiet! continua a essere un riferimento per chi cerca il meglio nel raffreddamento silenzioso. Consiglio queste ventole senza esitazioni a chiunque voglia un prodotto di qualità superiore.

Habe sie gegen meine Rise Aurora ausgetauscht und wurde nicht enttäuscht. Endlich ist mein System leise und effizienter
