The be quiet! Dark Rock Elite is a high-performance air cooler designed to handle demanding processors with a TDP of up to 280W. It utilizes seven 6mm copper heat pipes and a CNC-machined nickel-plated copper base, which is compatible with liquid metal thermal grease for efficient heat transfer. The aluminum fins feature a ceramic coating to enhance durability and thermal properties, while the overall black finish gives the system a clean, cohesive look. Two 135mm Silent Wings PWM fans with fluid dynamic bearings ensure a long lifespan of 300,000 hours and quiet operation, ranging from 11.0 to 25.8 dB(A). You can easily toggle between Quiet and Performance modes using a physical speed switch, adjusting the fan speed from 1500 to 2000 rpm. To ensure the cooler fits your specific hardware configuration, a rail system allows you to adjust the height of the front fan in five different steps. This cooler is built for enthusiasts using Intel sockets 1851, 1700, 1200, 1150, 1151, 1155 or AMD AM5 and AM4. Subtle ARGB LEDs on the top cover add a touch of personalization to your build. Weighing 1.34 kg and measuring 168mm in height, it provides a substantial cooling solution for those who prefer the reliability of air cooling without sacrificing aesthetic appeal.
