The PURE LOOP 2, in its quest to offer superior thermal conductivity, now features a water block with a nickel-plated copper base. This enhancement aligns with the preferences of gamers who favor ARGB (Addressable RGB) setups. Departing from the original design that featured pure white LED accents, the new version introduces a spectrum of colorful RGB lighting effects around the water block. This update provides users with the option to choose between two distinct styles for their water block: the classic understated elegance or a more vivid and dynamic RGB display.

Further adding to its aesthetic appeal, the cold head of the unit is adorned with a logo crafted from white metal thread, demonstrating meticulous attention to detail. This design choice not only adds a touch of sophistication but also ensures that the product’s appearance and texture meet the high standards Be Quiet! is known for. The PURE LOOP 2 stands as a prime example of a product that balances functional excellence with visual appeal, catering to a broad spectrum of user preferences without compromising on quality.

The PURE LOOP 2 features a unique design where the water pump is strategically positioned on the water pipe, rather than the more traditional placement on the water block or radiator. This design choice is particularly noteworthy as it contributes significantly to the unit’s overall efficiency and noise reduction.

To further enhance its vibration-dampening capabilities and minimize operational noise, the pump is encased in a double layer of rubber coating. This coating plays a crucial role in absorbing and reducing any vibrations that might arise from the liquid flow within the system. By mitigating these vibrations, the unit ensures a more stable and quieter operation.

The combined effect of the pump’s placement and its rubber coating, along with the water-cooled radiator, is instrumental in stabilizing the sound volume of the AIO system. This design approach aligns perfectly with Be Quiet!’s commitment to creating PC peripherals that operate efficiently while maintaining low noise levels, offering users a high-performance cooling solution without the common drawback of loud operational sounds.

The rubber-coated water pump reduces the vibration of the unit.

The water-cooling system of the PURE LOOP 2 is notably enhanced with a 12-channel aluminum radiator, designed for efficient heat dissipation. Complementing this radiator is a water-cooling pipeline encased in a braided coating, which not only adds to the durability but also to the aesthetic appeal of the unit.

An important aspect of this system is the maintenance ease it offers. The PURE LOOP 2 comes with a bottle of dedicated cooling supplementary fluid specifically for the cold radiator. The process of replenishing the coolant is user-friendly and straightforward. Users can simply use a screwdriver to open the screw on the radiator corresponding to the replenishment port, as detailed in the instruction manual. This replenishment process not only prolongs the service life of the radiator but also enhances its overall durability.

The fan component of the PURE LOOP 2 is equally impressive. It is equipped with the original Pure Wings 3 120mm high-speed version of the PWM (Pulse Width Modulation) fan. This fan features nine optimized blades, engineered to maximize airflow and minimize noise. Utilizing Rifle bearing technology, the fan boasts a long service life, estimated at 80,000 hours under normal room temperature conditions. Its maximum speed reaches up to 2100 RPM, ensuring effective cooling performance.

The included parts package is designed to support mainstream processors from both Intel and AMD, making the PURE LOOP 2 a versatile and user-friendly option for a wide range of PC builds. This combination of innovative design, ease of maintenance, and effective cooling technology makes the PURE LOOP 2 an appealing choice for users seeking a high-performance, low-noise cooling solution.
