The Dark Rock Pro C1 is a humongous “twin tower sandwich” style of cooler, weighting more than 1.5kg with its stock fans attached. A thick black aluminum plate is installed at the top of the cooler, serving mostly as an aesthetic enhancement but also helps with the mechanical cohesion of the gigantic cooling body. The aluminum plate covers the entire cooler except from the second cooling fan. The cooling fans are two of Be-Quiet’s best 120mm SilentWings series PWM controlled fans, which are also slightly faster than the single fan of the smaller Dark Rock Advanced C1. The SilentWings PWM is a high quality fluid dynamic bearing fan with an innovative fins design for optimum airflow performance and a maximum rotational speed of 1700RPM but without any lighting or other aesthetic enhancements.
The fins of the Dark Rock Pro C1 cooler are nickel plated and their fan-facing side is cut to a wave shaped pattern which is supposed to reduce turbulence noise. The fans are held into place by metallic wire brackets, coming in direct contact with the metallic cooling body. Unlike their wavy design of their fan-facing side, the back side of the fins is perfectly straight. The fins are also well cut and rounded, eliminating sharp edges and minimizing the risk of physical injury while handling the cooler.
Although the base of the cooler is nickel plated, it is actually made out of pure copper. The seven 6mm heatpipes move through the base and do not come in direct contact with the CPU; the heat is first absorbed by the base of the cooler and then transferred to the heatpipes, which in turn transfer the heat to the aluminum fins.
The base of the Dark Rock Pro C1 cooler is very well machined and considerably better than that of the smaller Dark Rock Advanced C1 cooler, forming a perfect mirror.
