Smart System Keeps Power Supplies Running Cool

The Redundant Cooling Power Supply intelligently detects and responds to increases in temperature that result from the breakdown of a simple fan, which is the weak link in power-supply cooling systems. The system includes an additional backup fan that operates independently from the primary fan and a thermal control circuit with a solid-state temperature sensor. The sensor detects ambient temperature changes inside the power supply and is connected to the power drives of both the primary and backup fans. The thermal control circuit works with the sensor to trigger a response whenever specific high and low temperature thresholds are exceeded. It enables the primary fan to increase its speed as temperatures rise. The system is available in 300W and 400W models.
