be quiet! Dark Rock Slim BK024 CPU Cooler - 180W TDP, 120mm PWM
The be quiet! Dark Rock Slim BK024 CPU Cooler is a compact tower cooler rated at 180W TDP, designed for enthusiast and high-end builds where case width or adjacent memory slots leave little room for a full-sized cooler. Its slim 72mm body clears standard memory modules without obstruction, and the included Silent Wings 3 fan keeps noise to just 23.6 dB(A) at full speed.
Why this product
180W TDP in a slim 72mm footprint
Despite its narrow 72mm width, it delivers 180W of rated thermal dissipation — enough for demanding mainstream and enthusiast CPUs without requiring a wide dual-tower design.
Clears memory slots without compromise
The compact construction is specifically shaped so it does not overhang or obstruct adjacent DIMM slots, making tall RAM kits a non-issue.
Silent Wings 3 fan runs virtually inaudible
The included 120mm PWM fan uses an advanced fluid-dynamic bearing and a 6-pole motor, producing only 23.6 dB(A) at its 1500 RPM maximum — and as low as 11 dB(A) at 50% speed.
Four copper heat pipes with wave-contoured fins
Four 6mm high-performance copper heat pipes carry heat away from the base, while wave-contoured aluminium fins increase air circulation across the stack.
Supports a second 120mm fan
Fan clips for an additional 120mm fan are included in the box, allowing a push-pull configuration if more headroom is needed.
3-year manufacturer's warranty
Backed by a 3-year warranty, with product concept, design and quality control carried out in Germany.

- The black installation kit mounts from above — check that your case lid or side panel provides sufficient overhead clearance for the total height of 159.4mm.
- Intel LGA 2011 and 2011-3 require the Square ILM bracket; the Narrow ILM variant is not supported.
Best for
- Tight mid-tower builds where a full dual-tower cooler would foul the side panel or memory slots — the 72mm width keeps clearances workable.
- Noise-sensitive environments — the Silent Wings 3 fan reaches only 23.6 dB(A) at full load and drops to 11 dB(A) at 50% speed.
- CPUs up to 180W TDP on both Intel and AMD platforms, covering a broad range of current-generation mainstream and HEDT sockets.
- Builders who value aesthetics — the brushed aluminium top cover with diamond-cut finish and all-black design suit windowed cases.
Trade-offs
- Very high-TDP CPUs above 180W — the rated thermal ceiling is 180W, so processors that regularly exceed this figure need a more capable cooler.
- Cases with less than 159.4mm CPU cooler height clearance — the cooler stands 159.4mm tall and will not fit in low-profile or very compact ITX enclosures with a lower limit.
- Intel LGA 2011 / 2011-3 Narrow ILM motherboards — only the Square ILM variant of those sockets is officially supported.
- Users who want a push-pull setup out of the box — the second fan is not included; only the mounting clips are provided.
