Amazon listing details

Marketplace feature text kept for reference. Structured specifications above are the source for scores and comparisons.

Pure Rock 3 Black is aimed at consumer PCs. With 190W TDP it offers an excellent cooling capacity for gaming, multimedia and graphics systems, as well as mainstream or entry level computers of all types.

Pure Rock 3 Black 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.

Pure Wings 3 120mm PWM and Pure Rock 3 Black are a perfect match. The fan features optimized fan blades for highest performance. The angles are adjusted to achieve even more air pressure, adding up to the extraordinary performance. A specially designed, funnel shaped air outlet is more than just the icing on the cake: it maximizes the airflow over the fins.

The Pure Rock 3 Black’s slim design increases RAM and VRM cooler compatibility significantly and enables limitless memory height. Thanks to its compact construction Pure Rock 3 Black is the perfect choice for PC cases that have limited space. Notwithstanding, it allows full configuration of RAM banks.

Installation is easier than ever with the Pure Rock 3 Black. 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.
