General Features

Quiet Operation

The 135mm Silent Wings PWM fan features nine airflow-optimized fan blades, a six-pole motor for less vibration, and a durable fluid-dynamic bearing. The heat sink also features a decoupled fan mounting with vibration-isolating elements.

Extreme Cooling Power

The Dark Rock 4 provides an TDP rating of 200W and achieves low temperatures even during periods of peak CPU performance.

Advanced Design

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

Single-Tower Layout

The compact single-tower design achieves strong heat dissipation in small spaces. While one fan is pre-installed, it is also possible to add another 120mm fan for improved cooling.

User-Friendly

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.
