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! ### ⭐⭐⭐⭐⭐ Top performer *by on Reviewed in the United Kingdom 20 September 2025* 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. ### ⭐⭐⭐⭐⭐ quiet and powerfull *by on Reviewed in the United Kingdom 17 July 2026* one of the best fans on the market ## Frequently Bought Together - be quiet!
