Cooling Architecture & Efficiency

At the core of the unit is a high-RPM pump coupled with a high-flow layout to ensure rapid heat removal from the CPU. A 120 mm radiator with ultra-fine fins combined with a top-class cooling fan (speed range ~800-2,000 RPM) ensures efficient heat dissipation and quiet operation under load. The use of hydro bearings, low-noise design and anti-vibration mounting contributes to stable performance in sustained workloads.

Build Quality & Platform Compatibility

The cooler’s mounting mechanism covers a wide range of Intel and AMD socket generations, making it future-proof for upcoming builds. The copper base plate ensures optimal thermal contact with the CPU heat-spreader, while the included tubing and external components are designed for reliability and long-term durability in demanding environments.
