The Dark Rock series has been a benchmark for premium air cooling since the Dark Rock Pro 2 earned a reputation for combining serious thermal performance with genuinely quiet operation. be quiet! is now ready with the sixth generation: the Dark Rock Pro 6 and Dark Rock 6, both scheduled to hit retail on May 19, 2026.
Starting with the flagship: the Dark Rock Pro 6 is a dual-tower design with seven high-performance heat pipes and two Silent Wings PWM fans in a 135mm and 120mm pairing. The company says the heatsink geometry has been redesigned from scratch for better heat dissipation versus the Pro 5. The nickel-plated copper base is compatible with liquid metal thermal compounds, and the asymmetrical layout includes cutouts to improve clearance over tall memory modules and VRM heatsinks. MSRP is $129.90 / €109.90 / £79.99.
The Dark Rock 6 is the single-tower option, featuring six heat pipes and a single 135mm Silent Wings fan. According to be quiet!, this model consolidates and replaces both the previous Dark Rock Slim and Dark Rock 5, giving it a broader positioning across different case sizes and performance tiers. It carries the same nickel-plated base and liquid-metal compatibility as the Pro. MSRP is $109.90 / €89.90 / £64.99.
The feature that will likely draw the most interest from enthusiasts is the hardware-controlled semi-passive mode, shared by both coolers. A physical switch on the cooler lets users toggle between active fan operation and semi-passive, where the fans stop entirely until the PWM signal reaches 40% and the system needs active cooling. For users building quiet workstations or lightly loaded gaming rigs, having fans that can stop completely at idle is a meaningful quality-of-life improvement. be quiet! has offered semi-passive modes in its PSU lineup for years, but this marks the feature’s arrival in the air cooler line.
Both coolers use the company’s ceramic-particle black coating, which be quiet! claims improves thermal transfer at the heatsink surface, and both ship with a magnetic top cover featuring a brushed aluminum accent badge. The mounting system uses a revised rail and fan bracket approach that the company says makes installation and maintenance easier than previous generations. Standard warranties are three years.
On the compatibility side, both coolers include an offset mount for AMD AM5 platforms to center the cold plate over the CPU’s known hot spots, addressing a complaint that has followed several coolers, including earlier Dark Rock models, since AM5 launched.
At these price points, the Dark Rock Pro 6 is going up against the Noctua NH-D15 G2 and the DeepCool Assassin IV (Ed: But not in the US, eh?).
