SHADOW ROCK LP
Exceptional Cooling, Significant Quiet

Fitting everything you want into a HTPC or Small Form Factor PC can be tough, quietly cooling those cramped components is far tougher. Shadow Rock LP is the ultra-compact CPU cooler from be quiet! that solves that problem.

Featuring four 6mm heat pipes, a Pure Wings 2 120mm PWM fan with airflow-optimized fan blades as well as an user-friendly mounting solution, Shadow Rock LP generates only 25.5dB(A) noise under maximum load yet boasts generous 130W TDP cooling capacity.

Shadow Rock LP is a space-saving wonder that brings be quiet!’s premium cooling technology to restricted spaces at a very attractive price point.

HIGH COOLING EFFICIENCY
Quiet and reliable cooling of your components
Shadow Rock LP offers a high cooling capacity of 130W TDP and is especially perfect for use in compact systems.

HIGH-PERFORMANCE HEAT PIPES
Offering fast and reliable heat transfer
Four 6mm heat pipes carry the heat efficiently and quickly to optimum locations on the cooling fins. This way the cooler achieves the best possible mixture of premium cooling performance in a restricted space and remarkably quiet operation.

WHISPER-SILENT PURE WINGS 2 FAN
Even at 100% fan speed, overall noise is a mere 25.5dB(A)
The Pure Wings 2 120mm PWM fan supports the best balance of perfect cooling and quiet operation. Nine silence-optimized fan blades generate high airflow characteristics that reduce noise-generating turbulences. The fan’s durable rifle-bearing technology contributes to a long lifespan of up to 80,000 hours.

EASY ACCESS, EVEN IN COMPACT PC ENCLOSURES
Highly convenient and compact design
Low-profile is a space-saving design that allows you easy access to components even in the very tight confines of compact PCs. This cooler also makes it possible to mount it from atop the motherboard, which adds further convenience.

Fractal Design Prisma AL Series ARGB fans allow your system to truly shine. Six hub-mounted addressable RGB LEDs work in harmony with a white semi-opaque outer ring and fan blades to produce a beautifully uniform glow across the fan’s entire surface.

Support for ASUS Aura, Gigabyte Fusion, MSI Mystic Light and ASRock Polychrome allows precision software control, enabling Prisma to synergize perfectly with your components. Those wanting more physical control can pair Prisma with the Adjust R1 controller to switch between colors, brightness, and motion effects with the push of button.

As with any Fractal Design fan, silence remains a central focus with integrated vibration damping corners, silent LLS bearings, and PWM options for complete control over the speed of your fans, ensuring Prisma is seen, not heard.

No Compromise Silence and Performance
The be quiet! Dark Rock Slim offers an exceptionally high cooling performance of 180W TDP and virtually inaudible operation. Perfect for high-end builds with limited space.

Pure Rock 2 is be quiet!’s CPU cooler for silent multimedia and graphics systems. It provides an excellent price-to-performance ratio with 150W TDP cooling efficiency, four 6mm heat pipes, a Pure Wings 2 120mm PWM fan and convenient design for mounting from atop the motherboard.

EXCELLENT COOLING EFFICIENCY
An exceptional price-to-performance ratio
Pure Rock 2 is aimed at the essential category of PC systems. With 150W TDP it offers an excellent cooling capacity for multimedia and graphics systems, as well as entry level computers of all types.

HIGH-PERFORMANCE HEAT PIPES
Ensuring perfect heat transfer
Pure Rock 2 is equipped with four 6mm heat pipes that have aluminum caps. This is key to its great cooling performance, because they transport the heat to optimum locations on the cooling fins.

SILENCE-OPTIMIZED OPERATION
Only 26.8dB(A) even at 100% PWM function
The Pure Wings 2 120mm PWM fan with high-quality rifle bearing facilitates the best balance between cooling performance and silent operation. The 9 blades of the fan are airflow-optimized to reduce noise-generating turbulence.

HIGHLY COMPATIBLE COMPACT DESIGN
Fits well into tight spaces
The asymmetrical construction does not block memory slots, saves space and makes Pure Rock 2 compatible with a full set of RAM modules. It is also very convenient to install, thanks to the fact you can mount it from above the motherboard.
