    Virtually Inaudible Operation

    Even at 100% PWM fan speed noise is an insignificant 24.3dB(A)

    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.




    Immense Cooling Power

    Achieving an incredible performance-to-noise ratio

    No compromise in silence and performance for overclocked systems and demanding graphics applications! Dark Rock Pro 4 provides an impressive rating of 250W TDP and achieves low temperatures even during periods of peak CPU performance.




    Highly Advanced Design

    The core features that result in high-end cooling

    Dark Rock Pro 4 is equipped with seven advanced technology 6mm copper heat pipes that maximize the heat conductance. Airflow-optimized, wave-contoured cooling fins with small dots on their surfaces increase the air circulation. The special black coating with ceramic particles makes a perfect transfer of heat possible.





    Double-Tower Layout

    Powerful cooling for your components

    Dark Rock Pro 4 contains two aluminum heat sinks. The cutouts provided enhance its RAM compatibility. Two fans are pre-installed. It is also possible to add another 120mm fan for even better cooling.
