be quiet! Dark Rock 5 BK035 CPU Cooler - 210W, 120mm PWM
The be quiet! Dark Rock 5 is a compact tower cooler rated for 210W TDP, designed for builders who want effective cooling with minimal noise. Its asymmetrical design and heat sink cut-outs maximize RAM and VRM cooler compatibility, and a second fan can be added later if extra cooling headroom is needed.
Why this product
6 copper heat pipes with ceramic-coated aluminum fins
The special black coating with ceramic particles optimizes heat transfer from the CPU to the air, enabling sustained cooling under demanding workloads.
Silent Wings 4 fan keeps noise down
Fluid-dynamic bearing, 6-pole motor, rubberized frame and tight blade clearance combine to run at 11.9 dB(A) at 50% fan speed—nearly inaudible in normal use.
Asymmetrical design clears tall RAM and VRM coolers
Heat sink cut-outs and a compact footprint mean it fits systems with high-profile memory and aftermarket VRM cooling without compromise.
Fits Intel and AMD sockets
Supports Intel LGA 1851, 1700, 1200, 2066, 1150, 1151, 1155 and AMD AM5, AM4.
Optional second fan for extra cooling
A second Silent Wings 4 120mm fan can be installed as an exhaust cooler for performance systems that need headroom above the 210W rated TDP.

- Intel LGA 1851, 1700, 1200, 2066, 1150, 1151, 1155
- AMD AM5, AM4
- Compatible with liquid metal thermal grease such as DC2 Pro thanks to nickel-plated base.
- Fits systems with tall RAM and most VRM coolers due to asymmetrical design, but verify your specific cooler height against the 136 mm width and 161 mm height envelope.
Best for
- Silent gaming and productivity builds rated up to 210W TDP
- Mid-range systems where RAM clearance matters—asymmetrical design avoids tall memory modules
- Quiet operation without aggressive fan noise—runs at 11.9 dB(A) at half speed
- Mixed-socket builders—covers recent Intel and AMD platforms in one purchase
Trade-offs
- CPUs exceeding 210W TDP without adding a second fan for load cooling
- Builders who prefer compact form factors—161 mm height requires adequate case clearance
- Systems with very aggressive overclocking on high-core-count CPUs near or above rated TDP
Dark Rock 5 is the compact embodiment of performance and high compatibility. With effortless installation and a silent fan, it is designed for passionate gamers of all kinds.
With 6 high-performance copper heat pipes and a dense aluminum fin array, Dark Rock 5 offers robust cooling. A special black coating with ceramic particles enables perfect heat transfer from the heat sink to the air, keeping your system cool under the most intense workloads.
For high performance and virtually inaudible operation · The Silent Wings 4 120mm PWM fan features an advanced fluid-dynamic bearing, smooth 6-pole motor and airflow-optimized fan blades.
The Silent Wings 4 120mm PWM fan features an advanced fluid-dynamic bearing, smooth 6-pole motor and airflow-optimized fan blades. Thanks to a tight tip clearance between fan blade and frame, the front fan provides extremely high air pressure. A funnel-shaped frame outlet enables ideal air distribution. The rubberized fan frame prevents vibrations from transferring to the heat sink, reducing overall noise.
The Dark Rock 5's asymmetrical design and heat sink cut-outs increase RAM and VRM cooler compatibility significantly and enable limitless memory height. Optionally, a second fan can be installed at the exhaust for an extra performance boost, making Dark Rock 5 a versatile marvel.
Installation is easier than ever with the Dark Rock 5. High RAM and VRM cooler compatibility thanks to an asymmetrical design and cut-outs on the heat sink.
