BeQuiet 's Shadow Rock Slim heatsink ships with a 135x22mm PWM fan that draws power from a standard 4-pin fan header. The 159mm tall heatsink uses four 6mm diameter copper heatpipes which pass through a 110mm tall fin stack. The raw aluminum fins measure 0.4mm thick and are spaced 1.8mm apart. The bottom-most fin is elevated 40mm above the socket for clearance.

The heatsink is 130mm wide and 74mm deep. The heat pipes are soldered to the copper base plate/aluminum top cap and swaged into the aluminum fins. The outer-most heatpipes are piped to the center of the base plate and the inner-most heatpipes to the outside of the base plate. This arrangement conducts CPU heat to the region of aluminum fins which receive the highest airflow.

The nickel plated copper base of the BeQuiet Shadow Rock Slim measures 40x40mm in size and is between 2-5mm thick. The aluminum support on the top-side of the heatpipes is 6.5mm thick. An aluminum bezel and turned caps give the heatsink a clean visual look at the top of the heatsink. The leading and trailing edges of each fin have a pair of winglets to help break up laminar airflow.
