THE DARK ROCK 3
Although the Dark Rock 3 is a single heatsink model it's still quite large and measures 160mm in height, 137mm in width and 97mm in length with a weight of 976g.
The 135mm SilentWings fluid dynamic bearing fan can spin up to 1400RPM to produce up to 67.8CFM of airflow with just 21.1dBA of noise.
The heatsink is made by a total of 51 dark nickel plated aluminum fins.
Thanks to the wave-contour design there's increased air circulation between the fins.
Be quiet! has placed their logo on a brushed aluminum plate with a diamond-cut finish at the top.
Six 6mm dark nickel plated all-copper heatpipes leave the base of the cooler and pass through all of the fins.
This small heatsink placed at the top is a new addition to the Dark Rock series (as far as i recall) and although it shouldn't be enough to make a significant performance impact it may actually help.
The base is flat and comes with a nice mirror like finish.
