FanMagic®-is a hardware-firmware device that realizes a temperature-based automatic-fan-speed control. Reducing of the fan speed as the temperature drops minimizes the system acoustic noise, prolongs fans service life period, diminishes power consumption. The controller assures early diagnostics of fan failures and increases reliability of hardware functioning due to the overall monitoring of cooling system and signalling in case of failures. The use of controller combined with the system with redundant cooling facilities allows to design fault-tolerant system with long-life performance.
FanMagicX includes all features of FanMagic and in addition:
- serial line communication with computer via COM-port.
- WatchDog timer (automatically restart the computer that is hung up).
