Reliable and versatile tower-type air CPU cooler with the traditional U-shaped layout of four 6 mm heat pipes, a nickel-plated copper base, a compact single-section heatsink, and Pure Wings 3 High-Speed 120 mm fans with long-life Rifle Bearing. It features a matte-black finish, moderate dissipated thermal power (up to 190 W at high fan speed), a light 570 g weight, two-sided mounting with a backplate, and sizable overall dimensions.

When choosing this cooling system, pay attention to the case width and the clearance from the CPU socket to the RAM slots. The aluminum heatsink consists of thin aluminum fins with a significant total surface area and a black coating. The be quiet! Pure Rock 3 Black CPU cooler can be installed on motherboards with Intel LGA1851/1700/1200/115X and AMD AM5/AM4 CPU sockets.

Thanks to its considerable cooling capacity, this model is suitable for cooling Intel or AMD processors in the Mainstream and Performance classes (excluding top-end and overclocking models whose TDP exceeds 190 W). It can cool CPUs running continuously with a small overclock performed without a significant increase in supply voltage. At minimum speed, the 120 mm fan operates silently (up to 12 dBA).

i bought it to replace the stock cooler for R5 1600 because it started making unpleasant noises and I wanted to try overclocking. For its price, this is probably the best cooler. It maintains 80 watts at less than 65°C on the quiet preset in BIOS with just one fan at the back. It looks great and has excellent factory thermal paste.
easy installation, appearance, silence, price
it's possible that the box is made from inexpensive cardboard and might not be suitable for box collectors (the cardboard texture is visible).
