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.

• Inner SilentWings 135mm PWM fan features: airflow-optimized blades, six-pole fan motor and FDB
• Decoupled fan mounting
• Seven advanced high-performance copper heat pipes maximize heat conductance
• Special wave-contoured cooling fins for silent airflow
• Small dots on the fin surface form a larger cooling area
• Fins have improved RAM compatibility (bottom fins feature cut-outs for memory)
• Special black coating with ceramic particles for perfect heat transfer
• Brushed aluminum top cover with high-grade diamond cut finish
• Convenient top mounting (screwdriver included)
• 250W TDP
• Support for an additional 120mm fan
• Projected release: Q2 2018

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. 

DARK ROCK 4 

Dark Rock 4 would be the successor of Dark Rock 3 and keeps most of its silence and performance, features distinction is mainly to be found in easier assembly through better mounting. Compared to the Pro version, this model is smaller with a single radiator and six heatpipes, it also lacks a second fan. The Dark Rock 4 is completely black coated. 

• SilentWings 135mm PWM fan features: airflow-optimized blades, six-pole fan motor and FDB
• Decoupled fan mounting
• Six advanced high-performance copper heat pipes maximize heat conductance
• Special wave-contoured cooling fins for silent airflow

Compared to Dark Rock 3:

The new features gave bequiet! the possibility to raise the TPD to 200W without losing the silence aspect. At the same noise level Dark Rock 4 provides better cooling performance than its predecessor.
