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

The 2 Silent Wings PWM fans feature advanced fluid-dynamic bearings, smooth 6-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.


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. 


The core features that result in high-end cooling

Dark Rock Pro 4 is equipped with 7 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.


Powerful cooling for your components

Dark Rock Pro 4 contains 2 aluminum heat sinks. The cutouts provided enhance its RAM compatibility. 2 fans are pre-installed. It is also possible to add another 120mm fan for even better cooling.


Stylish and easy to install

The mounting kit for the Dark Rock Pro 4 cooler is completely black, perfectly matching the black design of the cooler itself. You can conveniently install the cooler on the motherboard from above. The brushed aluminum top cover with its diamond cut finish adds a touch of elegance to this high-end cooler.

“The epitome of a high-end cooler: Dark Rock Pro 4 is the very best a be quiet! air cooler can offer and reliably cools even the most demanding, overclocked builds.” 

Marius Sabisz, Head of BU Cooling
