Inside Aice Cooling Technology
Aice combines direct TEC contact cooling with an optimized airflow system to cool your neck while efficiently releasing heat from inside the device.
Active Cooling
A large TEC-powered contact surface rests against the neck, drawing heat away across a broader area. This expanded cooling interface delivers focused cooling directly at the point of contact—going beyond the sensation of airflow alone.
Precision Airflow
Inside the system, one optimized airflow network performs two functions. The fan directs controlled airflow upward and downward around the neck, while simultaneously channeling air across the heat-dissipation fins on the hot side of the TEC module.
