Fan Monitoring

Monitoring Fan

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.

Monitoring fans is important as they ensure a proper temperature for optimal functioning of the system.

Depending on the available information, the Speed and/or Status parameters will be displayed for each detected fan device:

•	The Speed parameter represents the speed of the corresponding fan (in rotations per minute). An alert is triggered if the fan speed is too low for proper functioning.

•	The SpeedPercent parameter represents the speed of the corresponding fan in percentage of its maximal speed. An alert is triggered if the fan speed is too low for proper cooling.

•	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.
