The be quiet! Dark Rock Slim is a CPU cooler designed for those who need efficient thermal management in more compact system builds. It features four 6mm copper heat pipes and an aluminum fin stack, all finished with a black ceramic coating to protect the components and maintain a clean look. A CNC-machined copper base ensures a precise fit against the processor, while the brushed aluminum top cover with a diamond cut finish adds a refined touch to the interior of your case. Equipped with a Silent Wings 120mm PWM fan using a fluid dynamic bearing, this cooler balances performance and acoustics, reaching a maximum airflow of 50.5 CFM at 1500 rpm while keeping noise levels as low as 11 dB(A) at lower speeds. With a TDP of 180W, it can handle demanding workloads across a wide range of platforms, including Intel sockets from 1150 up to the latest 1851 and AMD AM4 or AM5. Its dimensions of 72 x 127 x 159 mm make it a practical choice for users who want high-end cooling without occupying excessive space, and you can optionally add a second 120mm fan if your specific setup requires extra airflow.
