Keep It Cool

Very high cooling performance
Pure Rock 3 LX is aimed at consumer PCs. With 190 W TDP it offers an excellent cooling 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 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 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. Thanks to its compact construction Pure Rock 3 LX is the perfect choice for PC cases that have limited space. Notwithstanding, it allows full configuration of RAM banks .
 




 
Super Easy Installation

No tutorial needed
Installation is easier than ever with the Pure Rock 3 LX. Thanks to its convenient, preinstalled mounting bridge plus screws and a firm yet gentle fixing method, cooler attachment is a breeze. 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? Pure Rock 3 LX comes in an unmistakable all-black design which perfectly complements the lighting effects its fan offers. Every little detail is carefully arranged, making Pure Rock 3 LX a design gem in its class.
