The be quiet! Dark Rock 6 redefines temperature control by introducing an innovative hardware switch on the cooler, which allows you to instantly change operating modes. You can choose the Active Performance Mode for extreme cooling power during intense gaming, or the Semi-passive Quiet Mode for absolute silence. In Quiet Mode, the cooler supports full fan stop for completely silent operation, stopping the fan entirely when the computer is under low load, offering an ideal silent performance experience.

At the heart of the Dark Rock 6 beats a top-tier Silent Wings 135mm PWM fan, meticulously designed to deliver perfect air pressure. Equipped with an advanced 6-pole fan motor and Fluid Dynamic Bearing technology, this fan offers a lifespan of up to 300,000 hours of operation. Even when running at 100% capacity, reaching 2000 revolutions per minute (rpm), it produces only 31.1dB(A) maximum noise level, remaining almost inaudible inside your hardware case.

One of the biggest problems with large CPU coolers is the limited space for RAM modules. be quiet! solves this issue by implementing a smart asymmetrical design with special cut-outs on the heat sink’s cooling surface. This component layout ensures high compatibility with high-profile RAM and bulky motherboard VRM heatsinks, allowing you to install your memory modules in any slot without any restrictions or risk of contact.

The Dark Rock 6 is equipped with 6 optimized high-performance heat pipes with a diameter of 6mm, which are in contact with a CNC machined base made of nickel-plated copper. These pipes instantly transfer heat from the CPU to the aluminum fins of the heat sink. The optimized heatsink body is designed to maximize airflow, offering top cooling power of 220W TDP. This means your processor will stay cool even under extreme overclocking conditions, preventing thermal throttling.

The appearance of the Dark Rock 6 is just as impressive as its performance, offering the elegant, signature look of be quiet! The entire surface features a special ceramic-particle black coating, which, in addition to its premium matte feel, actively contributes to better heat transfer. The ensemble is completed with an impressive magnetic top cover, which hides the ends of the heat pipes and gives a clean, minimal aesthetic to the interior of your computer.

The cooler offers complete compatibility with the modern sockets on the market, supporting Intel 1851 / 1700 / 1200 as well as AMD AM5 / AM4, and is also fully compatible with liquid metal thermal grease. The package includes an easy mounting system for effortless installation, premium thermal paste, and a special screwdriver.
