The be quiet! Dark Rock 6 is a high-performance air cooler designed to keep powerful processors stable under heavy loads, supporting a TDP of up to 220W. It utilizes six 6mm copper heatpipes and aluminum fins with a ceramic coating to efficiently move heat away from the CPU. The base is made of nickel-plated copper and features a CNC-machined surface, which makes it compatible with liquid metal thermal grease for those seeking maximum thermal conductivity. To keep noise levels low, the cooler uses a 135mm Silent Wings PWM fan with a 6-pole motor and fluid dynamic bearing technology, ensuring a lifespan of 300,000 hours. You can choose between a Performance mode or a Semi-passive Quiet mode via a hardware switch, the latter of which stops the fan entirely when the PWM signal drops below 40%. Its asymmetrical shape prevents interference with your RAM and VRM components, while a magnetic top cover allows for easy installation and a clean look. This cooler fits a wide range of modern systems, including Intel LGA 1851, 1700, 1200, 1150, 1151, 1155 and AMD AM5 and AM4 sockets. Weighing just over 1 kg, it provides a substantial thermal mass for enthusiasts and professionals who need reliable cooling for demanding workstations or gaming PCs.
