be quiet! Pure Rock Pro 3 LX Black ARGB Dual Tower Air Cooler
FEATURES
- The be quiet! Pure Rock Pro 3 LX BK043 is a high-performance dual-tower CPU air cooler designed for modern gaming PCs, workstations and demanding desktop systems. With a cooling capacity of up to 250 W, six high-performance 6mm heat pipes and two Light Wings LX 120mm PWM ARGB fans, it combines powerful thermal performance with customizable lighting.
- The dual-tower heatsink uses six copper heat pipes with a nickel-plated base to transfer heat efficiently away from the processor. The large aluminum fin array provides an extensive surface area for heat dissipation, while the CNC-machined CPU contact surface is designed to provide efficient heat transfer between the processor and cooler.
- Two Light Wings LX 120mm PWM fans provide airflow through the heatsink. Each fan operates at up to 2000 RPM and delivers airflow of up to 61.8 CFM (105.1 m³/h), with air pressure reaching 2.51 mmH₂O. The funnel-shaped air outlet helps direct airflow through the heatsink fins for effective cooling.
- The Pure Rock Pro 3 LX also adds addressable RGB lighting to the Pure Rock Pro design. Each Light Wings LX fan features 16 LEDs positioned in the fan hub to illuminate the translucent fan blades. The ARGB lighting can be connected to a compatible motherboard or controller for customizable system lighting.
- The fans use 4-pin PWM connections, allowing compatible motherboards to automatically regulate fan speed according to CPU temperature and workload. At maximum speed, the cooler reaches a noise level of 34.8 dB(A), providing a balance between cooling performance and acoustic output.
- Its compact offset dual-tower design improves compatibility with RAM and VRM heatsinks, while the front fan height can be adjusted when required. The mounting system supports Intel LGA 1851, 1700, 1200, 1150, 1151 and 1155 sockets, as well as AMD AM5 and AM4 platforms.
- Finished in an elegant all-black design with ARGB illumination, the be quiet! Pure Rock Pro 3 LX BK043 is well suited to gaming PCs, content-creation systems and high-performance workstations. With 250 W cooling capacity, six heat pipes, dual 120mm PWM ARGB fans and broad platform compatibility, it provides a powerful and visually customizable CPU cooling solution.
