Highly Advanced Design

The core features that result in high-end cooling
Dark Rock 4 is equipped with six 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.
 

 
 
Single-Tower Layout

Powerful cooling for your components
The compact single-tower design achieves excellent heat dissipation in small spaces.  One fan is pre-installed. It is also possible to add another 120mm fan for even better cooling.
