BeQuiet's Dark Rock TF heatsink is equipped with two 135mm PWM fans that exhaust downward. The fans draw power from separate 4-pin fan headers so a short Y-splitter is included. The 130mm tall heatsink uses six 6mm diameter copper heatpipes bent into a large "G" shape. The heatpipes pass through two horizontal cooling fin stacks, the first 131x140x35mm in size, the second measures 98x64x27mm. In each case, aluminum fins measure 0.3mm thick and are spaced ~2.0mm apart. The bottom of the second fan is elevated 58mm above the CPU socket. Note the rubber pads on both sides of the upper fin stack for the fans to rest against.

The dark nickel plated heatpipes are soldered to the nickel plated copper base plate and smaller cooling fin section, while the upper set of cooling fins are swaged in place. Six heatpipes intersect the top set of aluminum fins in a straight row, four heatpipes intersect the bottom row of fins. Wire fan clips hold both 140mm fans in place upon small rubber vibration absorbing bumpers.

The leading and trailing edges of each cooling fin have a shallow concave profile with small notches, this forms a plenum behind/in front of the fans. The nickel plated copper base of the BeQuiet Dark Rock TF heatsink measures 40x43.5mm in size and is between 2-5mm thick. The aluminum cap on the top-side 8mm thick and supports the mounting brackets. Aluminum bezels and heatpipe caps have been added for a cleaner visual appearance.
