Be Quiet! Dark Rock Slim Air Cooler Review

Features & Specifications

COMPACT CONSTRUCTION – Powerful cooling in small spaces

The compact design achieves excellent heat dissipation in small spaces, making the Dark Rock Slim the perfect solution for high-end builds with limited space. Due to its compact construction, no memory slots are blocked. 

VIRTUALLY INAUDIBLE OPERATION – Only 23.6dB(A) even at 100% PWM fan speed

The Silent Wings 3 120mm PWM fan features seven airflow-optimized fan blades, a six-pole motor for less vibration and a durable fluid-dynamic bearing. Decoupled fan mounting with vibration-isolating elements on the heat sink.

EXCEPTIONALLY HIGH COOLING POWER – Achieving an incredible performance-to-noise ratio

Dark Rock Slim provides an impressive rating of 180W TDP and achieves low temperatures even during periods of peak CPU performance. It is also possible to add another 120mm fan for even better cooling.

HIGHLY ADVANCED DESIGN – The core features that result in high-end cooling

Dark Rock Slim is equipped with four 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.
