CPU Cooler be quiet! Dark Rock 6 - BK046

be quiet! Dark Rock 6 is a high-end air CPU cooler, aimed at serious gaming and workstation configurations where you seek silence and stable temperatures. It is compatible with modern Intel and AMD platforms, including LGA 1700 / LGA 1851 and AM4 / AM5, making it a good option for upgrades with future generations of processors. The large 135 mm fan and dynamic fluid bearing are oriented towards low noise and long life, while the black design looks good in most builds. If you want serious air cooling without the extra drama of pumps and liquids, this model fits very well.

What you get is a massive air cooler with an asymmetric design that does not conflict with RAM modules and VRM coolers around the socket. The 135 x 135 x 25 mm fan spins in a range of 450 to 2000 RPM. The 4-pin PWM connector gives you full control via BIOS or software – you can set curves so that you don't hear it in idle, while keeping stable temperatures under gaming load. The additional cutouts on the heatsink help you install taller RAM modules without fighting compatibility issues.

• Air cooling – simpler, reliable, and without the risk of leaks, ideal if you want to avoid the maintenance of AIO solutions.
• Compatibility with CPU sockets: LGA 1150, 1151, 1155, 1156, 1200, 1700, 1851, AM4, AM5 – you can use it in a wide range of builds, from older to the newest platforms.
• 135 mm fan (135 x 135 x 25 mm) – a larger fan means good airflow at lower speeds and less noise.
• Range 450 – 2000 RPM – the wide range allows a quiet mode for light tasks and aggressive cooling for rendering or heavy gaming.
• Dynamic fluid bearing – provides smoother operation and better durability over time compared to basic sleeve bearings.
• 4-pin PWM connector – full automatic control of speeds based on CPU temperature, without manual micromanagement.
• Asymmetric design with heatsink cutouts – better compatibility with tall RAM modules and massive VRM coolers around the socket.

Who it is suitable for – if you are assembling a mid-range to high-end gaming or workstation configuration and want a quiet machine with good air cooling, Dark Rock 6 is a logical choice. It is also suitable if you often change platforms, as it covers a large number of sockets. If you are chasing extreme overclocking with an open bench and noise doesn't interest you, you will probably look towards more niche solutions, but for a real daily build, this is a very balanced option.

The combination of a large 135 mm fan, wide RPM range, and asymmetric design for high compatibility makes Dark Rock 6 a practical choice for a serious but quiet build. You install it once and forget it exists – which for a CPU cooler is exactly the desired effect.
