Key Features

Pure Rock Pro 3 LX features 6 high-performance copper heat pipes with nickel-plated base. As a result, this high-end cooler always keeps your CPU at peak performance, even in overclocked systems and demanding workstations. The performance is further increased by funnel-shaped air outlets on the Light Wings LX 120mm PWM fans, which increases airflow over the fins. In addition, the fan blades are optimized for maximum airflow, making this fan the ideal match for Pure Rock 3 LX.
16 LEDs are located inside the hub of the impeller of the Light Wings LX 120mm PWM fans and shine outwards onto the frosted fan blades. This creates an unmistakable look and enables you to express your creativity.
Despite being a double-tower air cooler, Pure Rock Pro 3 LX’ compact offset design increase RAM and VRM cooler compatibility significantly. The height of the front fan can be adjusted, if needed.
Installation is easier than ever with the Pure Rock Pro 3 LX. Its mounting kit is self-explanatory and easy to use, making attaching the cooler a breeze. Users of an AM5 CPU by AMD can benefit from an offset mounting to center the base plate above the hot spots of their CPU.
Powerful. Strong. Unshakable. The Pure Rock Pro 3 LX makes a statement not only in performance, but also in design. We made sure the cooler leaves a lasting impression in your PC. Despite its striking appearance with ARGB lighting, its lines are discreet, perfectly combining power and elegance.
