DARK ROCK 4NO COMPROMISE SILENCE AND PERFORMANCE Dark Rock 4 provides an extreme cooling performance of 200W TDP and virtually inaudible operation. Perfect for overclocked systems and demanding workstations. - Virtually inaudible Silent Wings 135mm PWM fan- Achieves only 21.4dB(A) at maximum fan speed- 6 high-performance copper heat pipes- Airflow-optimized, wave-contoured cooling fins- Easily installable black installation kit can be mounted from above- Supports an additional 120mm fan; clips are included in scope of del*very- Brushed aluminum top cover with diamond cut finish- 3-year manufacturer's - German product conception, design and quality control More VIRTUALLY INAUDIBLE OPERATIONEven 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 POWERAchieving an incredible performance-to-noise ratioNo 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 DESIGNThe core features that result in high-end coolingDark 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 LAYOUTPowerful cooling for your componentsThe 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 ELEGANCEStylish and easy to installThe 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.
