The be quiet! Pure Rock Pro 3 BK042 is a high-performance dual-tower air cooler designed for mid-to-high-end CPUs up to 250W TDP. Featuring six 6mm nickel-plated heatpipes, a nickel-plated copper baseplate, and aluminum fins, it delivers efficient heat dissipation while maintaining whisper-quiet operation from 14dB(A) at low speeds to 34.8dB(A) max.

Equipped with two optimized Pure Wings 3 120x25mm PWM fans (2000 RPM max, 101.2 m³/h airflow, 2.41 mmH₂O pressure), the cooler uses 4-pin PWM for precise speed control. Its compact 155mm height and offset fan design ensure high compatibility with tall RAM modules and VRM heatsinks. Easy installation via intuitive mounting kit supports Intel LGA1851/1700/1200/1150/1151/1155 and AMD AM5/AM4 sockets. Compatible with liquid metal thermal grease.
