be quiet! PURE ROCK PRO 3 LX, 2x120 mm ARGB CPU Cooler, Black

The PURE ROCK PRO 3 LX is a dual-fan air cooling solution engineered to manage thermal loads up to 250 W TDP. Heat transfer relies on a nickel-plated copper base plate connected to six 6 mm copper heat pipes, which distribute thermal energy across the aluminum fin stack. This robust configuration is intended to maintain stable operating temperatures for high-performance processors under load. The overall height of the cooler stands at 155 mm, assisting buyers in verifying case clearance before installation.

Two 120 mm fans utilize Rifle bearings and PWM support, enabling rotational speed adjustments between 0 and 2000 RPM based on thermal demand. These fans generate an airflow rated at 105.1 m³/h (61.8 CFM) and a static pressure of 2.51 mmH₂O for effective heat stack penetration. At maximum operational speed, the noise output is measured at 34.8 dB. The cooling unit supports a wide selection of Intel and AMD platforms, including LGA 1700/1851 and AM5 sockets.
