## Summary description

The be quiet! Dark Rock 6 is a high-performance air cooler featuring a 13.5 cm fan with a maximum rotational speed of 2000 RPM. It delivers an airflow of 89.95 m³/h and 2.48 mmH2O air pressure. Equipped with a durable Fluid Dynamic Bearing (FDB), this black CPU cooler ensures efficient heat dissipation and quiet operation for Intel and AMD systems.

## Long description

The be quiet! Dark Rock 6 is a high-performance CPU air cooler designed to provide efficient thermal management while maintaining near-silent operation. Featuring a 13.5 cm Silent Wings PWM fan, this cooler utilizes a Fluid Dynamic Bearing to ensure longevity and minimal noise levels. Its sophisticated black design, enhanced by a ceramic-particle coating, integrates seamlessly into modern PC builds, while the asymmetrical heat sink layout ensures high compatibility with various RAM modules and VRM cooling solutions.
Advantages
This cooler offers exceptional versatility through its hardware-based mode switch, allowing users to toggle between a performance-oriented cooling profile and a semi-passive quiet mode that stops the fan entirely under low loads. The inclusion of six high-performance heat pipes ensures rapid heat transfer away from the processor, maintaining stability even during intensive tasks. Furthermore, the mounting system is engineered for ease of installation, and the cooler is fully compatible with liquid metal thermal compounds for enthusiasts seeking maximum thermal conductivity.
Suitable for
High-performance gaming PCs
Quiet workstation builds
Systems requiring high RAM clearance
Intel and AMD desktop processors
When it may not be suitable
The Dark Rock 6 may not be suitable for ultra-compact small form factor (SFF) cases due to its 162 mm height, which might exceed the clearance limits of narrower chassis. Additionally, users performing extreme overclocking on high-TDP processors may find that a liquid cooling solution provides better thermal headroom under sustained maximum loads.
Key specifications
Fan diameter: 13.5 cm
Maximum rotational speed: 2000 RPM
Airflow: 89.95 m³/h
Air pressure: 2.48 mmH2O
Noise level: 31.1 dB(A) at maximum speed
Bearing type: Fluid Dynamic Bearing (FDB)
Dimensions: 139 x 102.4 x 162 mm
Supported sockets: Intel LGA 1851/1700/1200/115x, AMD AM5/AM4
How to use
Installation involves securing the appropriate mounting brackets for your specific CPU socket type to the motherboard. Once the backplate and brackets are in place, apply a small amount of thermal paste to the center of the processor heat spreader. Carefully mount the heat sink onto the processor, tightening the screws evenly to ensure optimal contact pressure. Finally, attach the 13.5 cm fan using the provided clips and connect the PWM cable to the CPU\_FAN header on your motherboard. Use the integrated hardware switch to select your preferred cooling mode.
What to consider before purchase
Check your PC case specifications to ensure it supports a cooler height of 162 mm.
Verify that your motherboard socket is listed among the supported Intel or AMD platforms.
Ensure your RAM modules do not exceed the clearance height provided by the asymmetrical design.
Usage recommendations
For the best thermal performance, ensure your PC case has adequate intake and exhaust airflow to assist the cooler in moving heat out of the system. If using the semi-passive mode, verify that your case fans are configured to provide sufficient ambient airflow to the CPU area.
