be quiet! Dark Rock Pro 6 CPU Air Cooler BK048 300W TDP
The be quiet! Dark Rock Pro 6 is a high-end CPU air cooler for heavily overclocked systems and demanding workstations that need both extreme cooling power and virtually silent operation. Its dual-mode design lets you switch between active performance cooling and semi-passive quiet mode, where the fans stop entirely below 40% PWM for completely silent running. Built around seven copper heat pipes and custom-designed Silent Wings fans, it handles up to 300W TDP while keeping noise levels between 7.5 and 32.4 dB(A).
Why this product
Dual-mode operation: performance or silent
A hardware switch toggles between active cooling mode for maximum performance and semi-passive mode where fans stop completely below 40% PWM, letting you choose quiet or cool depending on your workload.
Seven high-performance copper heat pipes
Dual-material construction—copper heat pipes and aluminium fins—delivers immensely high cooling power for heavily overclocked CPUs and sustained workstation loads.
Virtually inaudible Silent Wings fans
Custom 120mm and 135mm PWM fans use advanced fluid-dynamic bearings, 6-pole motors and optimized blades to deliver perfect airflow at up to 2000 RPM while staying nearly silent.
Wide socket compatibility
Supports Intel LGA1851, LGA1700, LGA1200, LGA1155, LGA1151, LGA1150 and AMD AM5, AM4 with pre-installed mounting bridge for quick installation.
Generous clearance for tall RAM and VRM coolers
Front fan uses rail system mounting with generous heat sink cut-outs, so it does not interfere with high-profile memory or voltage regulator module coolers.

Best for
- Overclocked CPUs and sustained high-performance workstations
- Builders who want silent operation without liquid cooling
- Systems with tall RAM modules or tall VRM coolers
- Users who value flexibility: switch between silent and maximum cooling modes
Trade-offs
- Compact cases: Dimensions are 147 × 140 × 169 mm, which exceeds the space available in many small-form-factor builds.
- Budget-conscious builds: This is a high-end cooler positioned for enthusiasts; lower-cost alternatives exist for standard workloads.
- CPUs above 300W TDP: Rated for 300W maximum; larger processors may exceed its thermal capacity.
- Builders who dislike manual mode-switching: Dual-mode operation requires a hardware switch; automatic thermal throttling is not available.
Dark Rock Pro 6 offers extremely high cooling performance and virtually inaudible operation. Excellent for heavily overclocked systems and demanding workstations.
Dark Rock Pro 6 raises the bar for silent cooling. Its mode switch lets you choose either active performance mode for advanced cooling power or semi-passive quiet mode, keeping the fan off below 40% PWM. Both modes ensure quiet and reliable performance in any workload.
Dark Rock Pro 6 features 7 optimized high-performance copper heat pipes, an optimized heat sink and specially refined fans. As a result, this high-end cooler keeps your CPU at peak performance at all times, even in heavily overclocked systems and demanding workstations.
For extremely high performance and virtually inaudible operation — the custom-designed Silent Wings 135mm PWM and 120mm PWM fans use advanced fluid-dynamic bearings, 6-pole motors and optimized blades. Thanks to tight tip clearance, they boost air pressure and improve the airflow.
Thanks to its convenient pre-installed mounting bridge and a firm yet gentle fixing method, cooler attachment is a breeze.
Dark Rock Pro 6 does not compromise when it comes to style. Custom-designed fans, side covers and a top cover that masks the heat pipe ends create the sleek, clean signature be quiet! design for Dark Rock CPU air coolers.
