KEEP IT COOL AND QUIET | Semi-passive quiet and active performance mode

Dark Rock Pro 6 raises the bar for silent cooling. Its mode switch lets you choose either active performance mode for advanced cooling power or semi-passive quiet mode, keeping the fan off below 40% PWM. Both modes ensure quiet and reliable performance in any workload.

EXTREMELY HIGH COOLING POWER | Even with heavily overclocked systems

Dark Rock Pro 6 features 7 optimized high-performance copper heat pipes, an optimized heat sink and specially refined fans. As a result, this high-end cooler keeps your CPU at peak performance at all times, even in heavily overclocked systems and demanding workstations.

CUSTOM-DESIGNED SILENT WINGS PWM FANS | For extremely high performance and virtually inaudible operation

The custom-designed Silent Wings 135mm PWM and 120mm PWM fans use advanced fluid-dynamic bearings, 6-pole motors and optimized blades. Thanks to tight tip clearance, they boost air pressure and improve the airflow.

EASY MOUNTING | Installation is a breeze

Thanks to its convenient pre-installed mounting bridge and a firm yet gentle fixing method, cooler attachment is a breeze. The front fan uses a rail system for mounting, which makes height adjustments easier and looks cleaner. So installation is easier than ever with Dark Rock Pro 6.

ICONIC DESIGN | Aesthetics meet functionality

Dark Rock Pro 6 does not compromise when it comes to style. Custom-designed fans, side covers and a top cover that masks the heat pipe ends create the sleek, clean signature be quiet! design for Dark Rock CPU air coolers.

COMPATIBLE WITH LIQUID METAL THERMAL GREASE | Cooling power beyond belief

Thanks to a nickel-plated base, Dark Rock Pro 6 is compatible with liquid metal thermal grease such as DC2 Pro. The properties of the liquid metal compound combined with Dark Rock Pro 6 allow high-end CPUs to perform at even higher levels.
