Extreme Cooling Power for Overclocked Systems
The be quiet! Dark Rock 4 offers an extreme cooling performance of 200W TDP and virtually inaudible operation, making it the perfect thermal solution for overclocked systems and demanding workstations. Designed to handle peak CPU workloads without breaking a sweat, this cooler delivers an incredible performance-to-noise ratio that ensures your high-end hardware maintains stable boost clock frequencies even during intense gaming sessions and heavy rendering tasks.
Virtually Inaudible Silent Wings Operation
Engineered for acoustic excellence, the pre-installed Silent Wings 135mm PWM fan operates at an insignificant 21.4 dB(A) even at 100% PWM fan speed. Featuring nine airflow-optimized fan blades, an advanced 6-pole motor designed to minimize vibration, and a durable fluid-dynamic bearing, the fan works alongside decoupled mounting elements on the heatsink to isolate vibrations and eliminate disruptive operational hums.
Highly Advanced Thermal Design
At the core of the Dark Rock 4’s superior thermal efficiency are six advanced technology copper heat pipes that maximize heat conductance away from the processor core. The airflow-optimized, wave-contoured cooling fins feature small dots on their surfaces to increase air circulation and turbulence control. Furthermore, a special black coating infused with ceramic particles facilitates a flawless transfer of heat across the entire fin stack.
User-Friendly Elegance and Versatile Layout
The compact single-tower design achieves excellent heat dissipation even in space-constrained builds while supporting the addition of an optional second 120mm fan for enhanced cooling configurations. Topped with a stylish brushed aluminum cover featuring a diamond cut finish, the Dark Rock 4 combines aesthetic sophistication with convenience. Its completely black mounting kit allows for easy, hassle-free installation directly from above the motherboard.
