Aerospace-Grade Aluminum Chassis

Aerospace-Grade Aluminum Chassis

Aluminum chassis integrates a diamond-matrix grill for robust durability and efficient airflow, achieving a perfect synergy of superior cooling and tech-inspired aesthetics.

Copper Base & 6 Heat-Pipe Array

Copper Base & 6 Heat-Pipe Array

The pure copper heat spreader instantly captures CPU heat, which is then efficiently distributed and dissipated by the six high-performance heat pipes for dramatically lower temperatures.

Powerful Dual Turbine Fans

Powerful Dual Turbine Fans

They generate a powerful, focused airflow to efficiently exhaust heat to prevent heat buildup.

Advanced Phase Change Material

Advanced Phase Change Material

It liquefies under heat to perfectly fill microscopic imperfections between the chip and cooler, resulting in superior thermal transfer compared to standard pastes.
