be quiet! Silent Wings 4 140mm High-Speed White Fan Review

Epilogue

The high-speed version of the be quiet! Silent Wings 4 120mm fan has top-notch build quality and also features a silent operation, although not as silent as be quiet! claims since I measured 5 dBA higher noise output at full speed than the manufacturer’s claims. The overall performance doesn’t stand out from the crowd and there is no daisy-chain option, although the fan’s power consumption is not that high to require a special power adapter for daisy-chaining several fans of this model.

Let’s look now at 25 dBA noise normalized performance. I chose 25 dBA because it is low enough not to annoy most users, while it is high enough to allow for speeds that offer decent performance in airflow and static pressure.

The be quiet! Silent Wings 4 doesn’t perform well in either airflow or static pressure. I expected higher performance here, given that this is supposed to be a high-end fan focusing on performance and low noise output. Yet, a quick look at the fan speed charts in the normalized noise tests shows that its noise design isn’t that effective since it doesn’t achieve top rotation speeds.

The Arctic P14 Max is a very good option if you need a top-performing yet affordable 140mm fan. The InWin Neptune AN140 is also a very good option, and it won’t break the bank.
