be quiet!, the market leader in PC power supplies in Germany for twelve consecutive years, announces Dark Rock Pro TR4, its high-end air cooler for AMD's Ryzen Threadripper processors. Dark Rock Pro TR4 is part of the Dark Rock 4 cooler family and features a large base plate, optimized for Socket TR4 CPUs. With a sleek design and smart optimizations, Dark Rock Pro TR4 targets demanding workstation users needing the best performance at extremely low noise levels.Thanks to a combination of high-end features and a base plate tailored for Socket TR4, Dark Rock Pro TR4 provides enough cooling performance for processors at a TDP rating up to 250 watts with a noise level of just up to 24.3 db(A). A Silent Wings 135mm PWM fan with airflow-optimized blades, a reliable six-pole motor, and fluid dynamic bearing (FDB) sits in the middle between the two cooling towers. For intake, Dark Rock Pro TR4 features a Silent Wings 3 120mm PWM fan with a funnel-shaped vent at the front of the heatsink. The fan mounting uses a decoupled design to minimize vibration, thus reducing noise.Dark Rock Pro TR4's cooling fins and heat pipes use a specially enhanced ceramic black coating, which not only gives it an appealing all-black design, but also improves the cooler's heat conduction. The heat transfers efficiently from base to heatsink through seven high-performance copper pipes. Small dots on the fin surface increase the total cooling area, while a wave-contoured shape contributes to perfect air flow.With Dark Rock Pro TR4, be quiet!'s top-of-the-line air cooler range now features a model refined for AMD Ryzen Threadripper processors. Emphasis is not just placed on performance, but also on build quality, utility and appearance, while installation is simplified thanks to an easy-to-use top mount design (screwdriver included). The cooler's brushed aluminum top cover features a high-grade diamond cut finish, while specially manufactured caps mask heat pipe ends and screw holes. To improve compatibility with high-performance RAM using tall heat spreaders or LEDs, Dark Rock Pro TR4 features formfitting cutouts at the bottom fins.The Dark Rock Pro TR4 CPU cooler is now available for €86,90 / £80.99 / $89.90 MSRP.
