Upgrade your PC’s cooling with the be quiet! Pure Rock 3 Black, Air cooler, 12 cm, 2000 RPM, 101.2 m³/h, Black. Its compact size hides a powerful cooling engine that keeps your processor cool while staying whisper‑quiet. You’ll feel the performance boost instantly, whether you game, stream, or work.
The Pure Rock 3 Black features a 12 cm Pure Wings 3 fan with PWM control, delivering up to 101.2 m³/h airflow at just 12.4 dB on low speed. Four 6 mm copper heat‑pipes spread heat efficiently across an aluminum fin stack, while the rifle bearing guarantees 80,000 hours of reliable operation.
Installation is fast thanks to the pre‑installed mounting bridge and comprehensive kit that supports Intel LGA 1150‑1700 and AMD AM4/AM5 sockets. You can have the cooler mounted and ready in minutes, even in tight cases.
The low‑profile design (15.4 cm height, 4.6 cm depth) fits easily into compact builds without sacrificing the 190 W TDP cooling capacity you need for demanding CPUs.
