Efficient Tower Cooling
The Great Wall ZM400i is a versatile tower-style air cooler built to provide superior thermal management for mid-to-high range CPUs. Equipped with four pure copper heatpipes that use Direct-Touch technology, it ensures rapid heat transfer from the processor to the large aluminum fin stack for maximum dissipation.
Key Features
- Direct-Touch Technology: Four 6mm copper heatpipes make direct contact with the CPU for minimized thermal resistance.
- High-Density Fin Stack: Precision-engineered aluminum fins maximize the surface area for efficient heat exchange.
- Silent 120mm PWM Fan: Automatically adjusts speed between 800 and 1600 RPM to balance cooling performance and acoustic comfort.
- Broad Socket Support: Fully compatible with Intel LGA 1700/1200/115X and AMD AM4/AM5 platforms.
- Hydraulic Bearing Fan: Ensures a long lifespan and quiet operation compared to standard sleeve-bearing fans.
