be quiet! BK018 Dark Rock 3 CPU Cooler with 135mm Silent Wings Fan overview

No Compromise Silence and Performance

Dark Rock™ CPU coolers have long been category leaders, and now the significantly upgraded Dark Rock 3 is even more powerful. This virtually inaudible single-tower CPU cooler puts famous be quiet! SilentWings® technology in your PC where it really counts. They are excellent for overclocked systems and demanding multi-graphics platforms.

Dark Rock 3 offers top performance-to-noise ratio and the highest reliability available. Improved cooling efficiency (190W TDP) and really silent operation (only 21.1dB(A) at maximum speed) mean this cooler strikes the perfect balance between cooling and serenity — truly silence and performance without compromises.

Extremely high cooling efficiency
  • Improved dynamic wave-contour cooling fins with enhanced cooling area and small dots on the surface increase air circulation and contribute to high convection efficiency without raising overall noise
  • Support of additional 120mm fan for extreme cooling performance (free fan clips are included in the scope of delivery)
  • Six high-performance heat pipes with copper lining and aluminum caps carry heat to the optimal location on the cooling fins, maximizing heat conductance
  • The extremely high cooling capacity of 190W TDP offers low temperature even at peak performance
  • New arrangement of heat pipes enhances the cooling capacity


  • Virtually inaudible operation
  • Improved 135mm SilentWings® PWM fan features:
  • Nine airflow-optimized fan blades
  • Innovative 6-pole motor for smoother operation and less vibration
  • Dynamically-balanced impeller
  • Advanced fluid dynamic bearing with copper core
  • Decoupled fan mount with vibration-isolating elements on the heat sink
  • Maximum noise is at scant 21.1dB(A) even at 100% PWM function


  • Product conception, design and quality control in Germany
  • Compatibility with all current Intel® and AMD™ sockets
  • Completely dark nickel-plated heat sink
  • Brushed aluminum top cover with high-grade diamond cut finish
