The be quiet! Dark Rock Pro 6 is a high-performance air cooler designed to keep powerful PC processors stable under heavy loads. It manages a recommended TDP of 300W using an aluminum radiator and two 135 mm fans equipped with fluid dynamic bearings, which help maintain a balance between cooling efficiency and longevity. These fans operate at speeds up to 2000 rpm, delivering a maximum airflow of 52.9 cfm while keeping noise levels at 34.4 dBA. To give you more control over your acoustic environment, the cooler includes a mode switch that lets you choose between Performance for active cooling and a Quiet semi-passive mode where the fans remain off below 40% PWM. The unit weighs 1340 g and measures 122 x 140 x 169 mm, fitting into a wide range of modern systems thanks to its compatibility with LGA 1851, 1700, 1200, 1150, 1151, 1155, as well as AM5 and AM4 sockets. This makes it a reliable choice for users who need substantial thermal headroom for demanding tasks without relying on liquid cooling.
