Overstated advertised power
Advertised to cool a processor consuming 220 W, it isn't capable of doing so. For a processor drawing more than 200W, choose the PRO model, 50% more powerful.
The ventirad be quiet! Dark Rock 6 combines cooling efficiency and absolute discretion and is ideal for gaming setups and workstations. Designed for demanding users, it offers optimal heat dissipation, broad compatibility and near-silent operation, all in a compact and elegant design.

The Dark Rock 6 offers two operating modes: a semi-passive silent mode with complete fan stop for near-inaudible operation, and a performance mode for maximum heat dissipation. Thanks to its integrated switch, you can easily toggle between these two modes depending on your needs. With only 31,1 dB(A) at maximum speed, this cooler remains discreet even under heavy load. Its Silent Wings 135 mm PWM fan, equipped with a fluid dynamic bearing (FDB) and a 6-pole motor, ensures optimal air pressure and high airflow, while minimizing noise.
Featuring 6 high-performance copper heat pipes and a dense array of aluminum fins, the Dark Rock 6 ensures efficient heat dissipation. Its special black coating, incorporating ceramic particles, improves heat transfer. The asymmetrical design and cut-outs on the heatsink allow optimal compatibility with memory modules and VRM coolers, without space constraints. In addition, its nickel-plated base makes it compatible with liquid metal thermal pastes, such as DC2 Pro, for even more advanced thermal performance.


The Dark Rock 6 stands out with its clean and sophisticated design, with side covers and a magnetic top cover concealing the heat pipes. Its pre-installed mounting system and rails allow for quick and secure installation, without additional tools. Whether for a gaming PC or a workstation, this cooler combines aesthetics, performance and ease of use.
