THE DARK ROCK 4 & DARK ROCK PRO 4

Both coolers look great not only thanks to the redesigned brushed aluminum top covers but also thanks to the black ceramic coating.

As mentioned earlier the Dark Rock 4 heatsink features a total of 51 aluminum fins while the Dark Rock Pro 4 features a total of 90 aluminum fins (45 on each heatsink).

The wave contour fin design is featured only at the rear of both coolers (this design increases air circulation and contributes to high convection efficiency).

The redesigned brushed aluminum diamond cut top covers look great no matter how many times we check them out (they also help keep air from leaking upwards).

Be quiet! has equipped both coolers with long rubber pads to ensure zero vibration coming from the fans.

The Dark Rock 4 features six 6mm black coated copper heatpipes whereas the Dark Rock Pro 4 features a total of seven.

Both coolers feature polished bases without any kind of visible machine marks as seen above.

Again as mentioned earlier the Dark Rock Pro 4 cooler comes with a 120mm fan (placed at the front for zero clearance issues with memory modules) and a 135mm fan (middle) whereas the Dark Rock 4 comes with a single 135mm fan.

It may not be very easy to see in the above picture but the black ceramic coating is very easy to remove even while mounting/unmounting one of the fans so do keep that in mind.
