ThermaPAK’s Patented HeatShift Laptop Cooler is the most effective solution against laptop heat. In a recent CNET study the HeatShift Laptop Cooler was proven to lower laptop temperature by more than 10 degrees Fahrenheit and significantly outperformed USB cooling fans. Unlike the fan products that blow dirt and dust at your laptop the grooved channels on the HeatShift laptop cooler enhances airflow. Not only does the self cooling HeatShift dissipate heat faster and more effectively than alternative products, it uses no power (extends battery life), wires, or refrigeration - making it the most advanced laptop cooler you can buy. The HeatShift cools uniformly by using organic cooling crystals that dissipate heat away from your laptop allowing it to perform at its best while keeping your laptop at a safe temperature.
