be quiet! Pure Rock 3 LX CPU Cooler - 190W TDP, ARGB
The be quiet! Pure Rock 3 LX CPU Cooler is a compact tower cooler rated for 190W TDP, designed for gaming and multimedia PCs where space and noise matter. It combines four 6mm heat pipes with a custom Light Wings LX 120mm fan featuring 16 addressable RGB LEDs and a noise level of just 31.2 dB(A) at full speed.
Why this product
Compact design with full RAM compatibility
The slim profile clears tall RAM modules and allows full memory configuration without obstruction, making it practical for most modern motherboards despite its cooling capacity.
Four 6mm heat pipes with HDT technology
High-performance heat pipes transport heat efficiently to the cooling fins with minimal bends, delivering strong thermal transfer across the 190W TDP range.
Quiet operation at maximum load
It reaches only 31.2 dB(A) at peak fan speed, keeping system noise low even during intensive workloads.
ARGB lighting with 16 LEDs
The hub contains 16 addressable LEDs that shine through frosted fan blades, offering customisable colour control via standard ARGB headers.

Best for
- Mid-range gaming and multimedia builds
- Cases with limited height or depth
- Builders who want RGB lighting without bulky custom loops
- Systems where noise matters
Trade-offs
- High-end overclocking. The 190W TDP rating sits below flagship coolers designed for extreme loads.
- Systems needing silent passive cooling. A 120mm single-fan design must run at some speed to handle sustained loads; passive-only cooling is not possible.
- Very compact ITX builds requiring minimal vertical space. The tower design demands space above the socket, even if it is narrower than many alternatives.
Pure Rock 3 LX rocks your system with very high performance in a compact design and a specially designed Light Wings LX 120mm PWM fan.
Pure Rock 3 LX is aimed at consumer PCs. With 190 W TDP it offers an excellent cooling capacity for gaming, multimedia and graphics systems, as well as mainstream or entry level computers of all types. The performance is further increased by funnel-shaped air outlets on the Light Wings LX 120mm PWM fans, which increases airflow over the fins. In addition, the fan blades are optimized for maximum airflow, making this fan the ideal match for Pure Rock 3 LX.
16 LEDs are located inside the hub of the impeller of the Light Wings LX 120mm PWM and shine outwards onto the frosted fan blades. This creates an unmistakable look and enables you to express your creativity.
Pure Rock 3 LX is equipped with 4 black 6mm heat pipes, matching the color of the heat sink. The heat pipes are key to the cooler's great cooling performance, because they transport the heat to optimum locations on the cooling fins. They do so with minimal bends and high bending radius, to maintain the performance of each heat pipe as good as possible.
The Pure Rock 3 LX' slim design increases RAM and VRM cooler compatibility significantly and enables limitless memory height. Thanks to its compact construction Pure Rock 3 LX is the perfect choice for PC cases that have limited space. Notwithstanding, it allows full configuration of RAM banks.
