Pure Rock Pro 3 is ready for modern flagship CPUs like Intel's Core i9 or AMD's Ryzen 9 series.

EXCELLENT COOLING CAPACITY

Double-Tower, double power

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.

IMPRESSIVE LIGHTING

Lots of illumination possibilities

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.

MULTIPLATFORM

High compatibility

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.

SUPER EASY INSTALLATION

No tutorial 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.

DESIGN UPGRADE

Makes your system look sharp

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.

"It takes a lot to earn the title "Pro" with us. Pure Rock Pro 3 definitely deserves it. I've been working at be quiet! for over 20 years now and I never thought that a Pure Rock cooler would have such cooling performance. It's amazing what we've achieved in all this time!"
