Our Verdict
79%
This 140mm PC case fan provides fantastic efficiency, airflow and low noise, but it’s not cheap.
On paper the Silent Wings 4 High Speed certainly boasts some hefty specs. Hitting a peak of 2,500rpm, this model offers a massive claimed 3.96mm H2O static pressure, in part thanks to small blade-tip clearances, while a six-pole motor and fluid-dynamic bearing reduce 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.
be quiet! Silent Wings 4 High Speed performance
Befiting the company name, these fans are very quiet – the second quietest we’ve tested, despite them also hitting a massive 2.6m/sec in airflow at maximum speed. That airflow speed is second only to the monstrous and deafening Phanteks T30. This gives the Silent Wings 4 HS the third best efficiency we’ve tested. It also 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.
