The be quiet! Pure Rock Pro 3 LX is a double-tower air cooler designed to handle demanding processors with a TDP of up to 250W. It utilizes six 6mm black copper heatpipes and a CNC-machined nickel-plated copper base to move heat efficiently toward the aluminum fins, which are treated with electrophoresis for a clean black finish. To keep the system cool, it features two 120mm Light Wings LX PWM fans that reach speeds of 2000 rpm, providing an airflow of 61.8 CFM while maintaining a noise level between 14.0 and 34.8 dB(A) depending on the load. These fans include ARGB lighting with 16 LEDs per hub, allowing you to integrate the cooler into your system's visual theme. Measuring 114 x 124 x 155 mm and weighing 1.08 kg, the cooler is built with an offset design that helps avoid interference with your RAM and VRM components. It is compatible with a wide range of sockets, including Intel 1851, 1700, 1200, 1150, 1151, 1155 and AMD AM5 and AM4, with a specific offset mounting option for AM5. Because it supports liquid metal thermal grease and comes with pre-applied paste, it suits enthusiasts building high-performance workstations or gaming PCs who need reliable thermal management without sacrificing aesthetics.
