Be quiet! Pure Loop 3 LX 240mm
The Be quiet! Pure Loop 3 LX 240mm liquid cooler efficiently dissipates heat from your processor, maintaining a low operating temperature even under heavy loads. This all-in-one liquid cooling solution combines a 240mm aluminium radiator with two Light Wings LX fans and a high-performance pump. The design ensures quiet operation and high cooling performance, which are key features of Be quiet! CPU coolers. The system supports modern Intel and AMD sockets, including AM4, AM5, 1700, and 1851. The closed loop with flexible 400mm tubes makes installation easy in most PC cases. The Pure Loop 3 LX is an ideal solution for users who demand reliable heat dissipation with low noise levels, while also appreciating the ability to visually customise their build with ARGB lighting.
Key features of the Be quiet! Pure Loop 3 LX 240mm liquid cooler
- Pump block with dynamic ARGB lighting and 10 interchangeable foils
- Two Light Wings LX PWM fans with daisy-chain support
- Pump with a 6-pole motor to minimise vibrations and noise
- Easy-access port for refilling the coolant
- High-performance cooling for all processors
- High-speed fans
- Sufficiently long 400mm tubes
Lighting and Light Wings LX fans
The liquid cooler's block features ARGB lighting, which you can customise with ten included foils for a unique visual style. It includes two Light Wings LX PWM fans, which offer 16 individually addressable LEDs for smooth lighting transitions. Nine blades with an optimised geometry for high static pressure effectively reduce turbulence and increase airflow through the radiator's dense fins, boosting cooling efficiency.
Wiring and cable management
The fan system supports daisy-chaining. This solution significantly simplifies installation by linking both the power and ARGB signals of both fans into a single bundle. Connecting the fans in a single chain eliminates the need for a separate ARGB/PWM hub and frees up connectors on the motherboard. The result is cleaner cable management inside the case and better airflow, unhindered by excess cables.
Cooling performance and quiet pump
The Pure Loop 3 LX 240mm provides high cooling performance that can handle even thermally demanding processors under full load. The pump features a modern 6-pole motor, the design of which effectively reduces vibrations and operating noise. PWM control of the pump speed, ranging from 3000 to 5500RPM, allows you to dynamically adjust its operation to the current system load. Under light loads, the pump runs quietly, while at high performance it prioritises a high coolant flow rate.
Maintenance and quality control
To maintain optimal performance in the long term, the cooler is equipped with an easily accessible refill port. This allows for simple topping-up of the cooling liquid, which extends the lifespan of the entire system. Designed and quality-controlled in Germany, this product meets strict standards for workmanship and reliability.
