Verdict

be quiet! Silent Wings 4 120mm PWM High-Speed

8 / 10 Expert Rating

More airflow than the quiet-first competition, with a bearing rating built for a decade of running.

Fractal Design Aspect 12 RGB PWM

7 / 10 Expert Rating

A tastefully understated RGB fan for builders who want lighting that doesn't fight their case's design language.
