VIRTUALLY INAUDIBLE OPERATION
Even at 100% PWM fan speed noise is an insignificant 21.4dB(A)
The Silent Wings 135mm PWM fan features 9 airflow-optimized fan blades, a 6-pole motor for less vibration and a durable fluid-dynamic bearing. Decoupled fan mounting with vibration-isolating elements on the heat sink.

EXTREME COOLING POWER
Achieving an incredible performance-to-noise ratio
No compromise in silence and performance for overclocked systems and demanding graphics applications! Dark Rock 4 provides an impressive rating of 200W TDP and achieves low temperatures even during periods of peak CPU performance.

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.

USER-FRIENDLY ELEGANCE
Stylish and easy to install
The mounting kit for the Dark Rock 4 cooler is completely black, perfectly matching the black design of the cooler itself. You can conveniently install the cooler on the motherboard from above. The brushed aluminum top cover with its diamond cut finish adds a touch of elegance to this high-end cooler.
