be quiet! Dark Rock PRO 4 review

Dark Rock Pro 4 offers an immense cooling performance of 250W TDP and virtually inaudible operation. Excellent for overclocked systems and demanding workstations. The two Silent Wings PWM fans feature advanced fluid-dynamic bearings, smooth six-pole motors and airflow-optimized fan blades. The front Silent Wings 3 fan provides extremely high air pressure, thanks to a funnel-shaped air inlet in the frame. Decoupled fan mounting with vibration-isolating elements on the heat sink.
