A large and high-performance tower-type air CPU cooler with a traditional U-shaped layout of six 6 mm heat pipes, a nickel-plated copper base, a large dual-section heatsink, and two 120 mm Pure Wings 3 High-Speed fans with long-life fluid-dynamic bearings. It features an impressive dissipated thermal power (up to 250 W, at high fan speeds), a substantial weight of 1070 g, and considerable overall dimensions.

When choosing this cooling system, be sure to check the case width, the clearance from the CPU socket to the RAM slots, and the height of the memory modules’ heatspreaders. The dual-section aluminum heatsink is made of thin aluminum fins with a large total surface area and a black matte coating. The be quiet! Pure Rock Pro 3 Black CPU cooler is compatible with Intel LGA1851/1700/1200/115X and AMD AM5/AM4/AM3 sockets.

Thanks to its significant cooling capacity, this model is suitable for cooling Intel or AMD processors in the Mainstream and Performance classes. It can cool CPUs that run constantly in a moderate overclock, including with a small increase in supply voltage. The device also deserves praise for its excellent acoustic characteristics — at minimum fan speed the fans are silent (14 dBA).
