To avoid overheating, system vendors install fans on critical devices (processors, power supplies, etc.). If a cooling system is not present, an overheated system can throttle the speed of processors and cause slow-downs or ultimately cause shut-downs. Monitoring fans is important since they ensure maintaining the right temperatures for optimal functioning of the system.
Depending on the available information, the following parameters will be displayed for each detected fan device:
| • | The Present parameter represents the availability of the fan. An alert is triggered if the fan is no longer discovered. |
| • | The Status parameter represents the current status of the fan. An alert is triggered if the fan stops spinning or does not spin fast enough. |
| • | The StatusInformation parameter gives additional information about the current status of the fan. |
