What is Smart Fan Adaptive Cooling?
Some models of Stealth’s Industrial Grade PCs employ the “Smart Fan Adaptive Cooling Feature” which is a Temperature/Speed controlled air fan option. Operating fans at full speed continuously can be disastrous to a computer operating in an industrial environment. The dust, not necessarily the temperature can be of most concern. Some installations have toxic particles in the air such as sulfur, which combines with the delicate copper traces on the computer cards. In time, those copper traces will pulverize causing a failure or even worse, a highly intermittent and difficult to diagnose fault. Even non-toxic dust, over time will create a film on the computer chips, virtually insulating the components from the benefits of airflow. Another consideration is the overall reliability of the components, which demands keeping thousands of the transistor junctions in the integrated chips at a fairly constant temperature. The speed of most DC fans is approximately proportional to the applied volta
