KEEP IT COOL Very high cooling performance Pure Rock 3 LX is aimed at consumer PCs. With 190 W TDP it offers an excellent c... moreooling capacity for gaming, multimedia and graphics systems, as well as mainstream or entry level computers of all types. 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 optimised 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 and shine outwards onto the frosted fan blades. This creates an unmistakable look and enables you to express your creativity. HIGH-PERFORMANCE HEAT PIPES Ensuring perfect heat transfer Pure Rock 3 LX is equipped with 4 black 6mm heat pipes, matching the color of the heat sink. The heat pipes are key to the cooler’s great cooling performance, because they transport the heat to optimum locations on the cooling fins. They do so with minimal bends and high bending radius, to maintain the performance of each heat pipe as good as possible. MULTIPLATFORM Second to none compatibility The Pure Rock 3 LX’ slim design increases RAM and VRM cooler compatibility significantly and enables limitless memory height.

Users of an AM5 CPU by AMD can benefit from an offset mounting to center the heat pipes above the hot spots of their CPU. DESIGN UPGRADE Makes your system look sharp Who says that neat looking products must be expensive?
