The heatsink base plate, grooves and gaps between the heatpipes in the base are exactly the same as by the previous cooler. And so is the finish quality of the base plate contact surface:
As for the evenness, things are even worse here:
Maybe the cross-concavity of the base plate is a unique trait of all beQuiet! coolers, but I doubt anyone will be happy with the thermal imprints like that:
Once we rotated the cooler by 90 degrees, the contact definitely improved, and so did the cooling efficiency:
The heatsink arrays are equipped with two beQuiet! SilentWings PWM fans, but the model here is a little bit different: BQT T12025-MF-PWM:
Their maximum rotation speed is a little higher – 1700 RPM. Looks like beQuiet! decided to increase the cooler efficiency not only by adding a second heatsink array and a second fan, but also by increasing the fans rotation speed. The maximum noise level is declared at 25.9 dBA, and the airflow from each of the fans is at 57.2 CFM. The bearing in this fan is exactly the same as in the other model, but the motor consumes 2.4 watts of power instead of 1.1 W. The fans are connected with a single four-pin cable:
The compatibility and installation of Dark Rock PRO C1 are exactly the same as those of the previously discussed Advanced C1 model, so here we will simply provide a link to the installation manual available online and a photo of the cooler inside the system case installed in two different positions:
If you want to equip your system with memory modules featuring tall heat-spreaders, make sure that they are no taller than 49 mm, because Dark Rock PRO C1 hangs over first two memory DIMM slots on the mainboard.
