  • Seven 6mm Copper Heat Pipes
  • Airflow-Optimized Fan Blades

Built to provide immense cooling performance for overclocked systems and demanding graphics applications, the Dark Rock Pro 4 Air Cooler from be quiet! features seven 6mm copper heat pipes, a 120mm Silent Wings 3 PWM fan, and a 135mm Silent Wings PWM fan with airflow-optimized blades with speeds of 1200 / 1500 rpm, six-pole motors, and fluid-dynamic bearings. Thanks to a funnel-shaped air inlet on the front fan, it provides extremely high air pressure. If you'd like to improve the Dark Rock Pro 4's cooling efficiency, an additional 120mm fan can be added. Living up to its name, this be quiet! product generates only 12.8, 17.9, and 24.3 dBA of noise under 50, 75, and 100% loads, yet offers a cooling capacity of 250W TDP. It has a lifespan of up to 300,000 hours and can be used with select Intel and AMD sockets.

General Features

Virtually Inaudible Operation

The two Silent Wings PWM fans feature 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. There is also a decoupled fan mounting with vibration-isolating elements on the heat sink.

Immense Cooling Power

The Dark Rock Pro 4 does not compromise in regards to silence and performance for overclocked systems and demanding graphics applications. It provides a rating of 250W TDP and helps achieve low temperatures, even during periods of peak CPU performance.

Advanced Design

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

Double-Tower Layout

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


The mounting kit for the Dark Rock 4 is completely black, matching the black design of the cooler itself. You can conveniently install the cooler on the motherboard from above, and the brushed aluminum top cover with its diamond cut finish adds a touch of style.
