Three PWM Fans for Superior Cooling Performance
The PURE LOOP 3 features three 120 mm PWM fans that work in harmony to move 101.2 m³/h of air through the radiator. These fans operate between 3000-5500 RPM, allowing precise control over cooling performance. The 9-blade design optimizes airflow while maintaining quiet operation, making this cooler suitable for both performance and noise-sensitive environments.
Universal Socket Compatibility for Modern Processors
This all-in-one liquid cooler supports a comprehensive range of processor sockets including the latest LGA 1851 and AM5 platforms. It’s specifically compatible with AMD Ryzen 9000 Series and Intel Core i9 processors, ensuring broad compatibility with current and recent-generation CPUs. The copper base plate provides excellent heat transfer across all supported platforms.
Quiet Operation with Intelligent Design
Operating at just 17.6 dB in low-speed mode, the PURE LOOP 3 maintains near-silent operation during light workloads. The pump runs at a consistent 5500 RPM, while the three fans can be adjusted from 3000-5500 RPM based on thermal demands. This intelligent design balances cooling performance with acoustic comfort, making it ideal for quiet computing environments.
Daisy Chain Cable Management
The included daisy chain feature simplifies cable routing by allowing multiple fans to be connected in series. This reduces cable clutter inside your PC case and improves airflow by eliminating obstructions. The 4-pin fan connectors ensure reliable power delivery and PWM control for all three fans through a single connection point.
