The heat emitted from the bottom of a laptop can reach temperatures as high as 115° Fahrenheit (46.11° Celsius or centigrade). The DefenderPad® allows the heat to flow away from the laptop and prevents all downward air flow from hitting the body. With this kind of proper flow pattern, laptops tend not to overheat while continuing to release potentially dangerous heat levels. In the process of diverting this heat, the DefenderPad® will absorb some portion of the heat and although warm, the heat on the bottom of the DefenderPad® is well within safely limits. This is accomplished with a thermally-resistive surface material on the top of the DefenderPad®.
The DefenderPad® does not haven cooling fans. It provides a clear venting heat path for laptop bottom heat which keeps the laptop operating without overheating and the bottom, a bit cooler. Laptops tend to overheat because there is not a proper path for heat ventilation, intake air vents may be clogged with dust or the laptops no longer operates as designed because of age.
