BE QUIET! SILENT WINGS 4

BE QUIET! SILENT WINGS 4 Fan Review

On paper, the Silent Wings 4 High Speed boasts some hefty specs. Hitting a peak of 2,500rpm, this model offers a massive claimed 3.96mm H2 O static pressure, in part thanks to small blade-tip clearances, while a six-pole motor and fluid-dynamic bearing reduces vibration and noise. The fans come with easy-to-use push-pin corner clips for mounting in cases, with separate clips for use with coolers and radiators. However, there’s no RGB lighting here.

Sound quality was exceptional, and at full speed, the be quiet! managed the second lowest noise level on test, despite also hitting a massive 2.6m/sec in airflow, which was second only to the monstrous and deafening Phanteks T30. This gave it the third best efficiency. It managed the lowest noise at 1,000rpm, but it did slip down the airflow table here to 0.76m/ sec, while the Phanteks T30 was only slightly louder and managed 0.9m/sec.

Still, the Silent Wings 4 High Speed beat the Phanteks in efficiency, and was a match for the Deepcool FC120, while it topped the chart in all three noise-normalized tests.

With superb high-speed airflow, excellent efficiency at all speeds and great sound quality, the fantastic be quiet! Silent Wings 4 High Speed is attractive for any situation. It won’t be cheap to kit out a PC case or large radiators, but if you want great airflow and static pressure with low noise, it’s worth every penny.
