be quiet! Silent Wings 4 120mm PWM High-Speed Fan, Optimized Fan Blades, Extraordinary High Performance, Extremely High Air Pressure, Very Silent Operation, 6-Pole Fan Motor, Fluid-Dynamic Bearing

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’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!

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

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

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.

all ok

I’m really impressed with these. Installed into a computer that is used in the lounge, keeps the noise to a minimum while still being powerful. Cools the computer adequately. Really easy to install with the help of YouTube. Definitely worth the money.

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..

Excellent fan! Reasonable price for a decent silent fan. I've had better ones in the past from Antec but they are no longer made so this was the closest thing. They still make a bit of vibration but overall they are perfect.

作業や動画視聴に集中したかったので、PCから出る音を極力下げるためにこちらの商品を購入しました。 実際に使用したところ音がほとんど聞こえず、耳をPCに近づけなければ聞こえないほどファンの回転音は小さいです。 風量も申し分なく、自分のPC環境ではSSD・HDD・CPU・GPUはしっかり冷却されております。 今後PCファンを購入する時はまたこちらのシリーズのファンを購入したいと考えております。

Bueno y barato

Muy silencioso las aspas giran sin ningúna resistencia, viene con 2 tipos de anclajes y tornillos para según donde se vaya a colocar.

Ottimo prodotto, veloce e silenzioso con ottima portata d'aria.
