BeQuiet! will be releasing the Dark Rock Pro 4 and Pro editions, the successor of Dark Rock Pro 3 processor cooler which keeps most of its silence and performance features compared to the model 3 versions.
The Dark Rock 4 and Dark Rock Pro 4 replace the model 3 released a few years ago. They have an improved mounting system making both models easier to assemble and install. They should be more silent as well. The Dark Rock Pro 4 model has a dual-tower design and sitting in-between the two is a a PWM-controlled SilentWings fan (135 mm). The solutions have a dual-fan setup in a push-pull configuration and as such you will spot a second SilentWings 3 (120 mm) fan at the outside. The pro has seven copper heat pipes and seems to have improved clearance space for DDR3/DDR4 compatibility (compared to the previous model). The cooler is coated completely dark, which looks pretty nice, to be honest.
DARK ROCK PRO 4
Dark Rock Pro 4 is the successor of Dark Rock Pro 3 and keeps most of its silence and performance features.
The new features gave bequiet! the possibility to lower the fan speed and therefore lower the noise level without losing any performance. Dark Rock Pro 4 is more silent than its predecessor while performing on the same high-end level.
