Thermal Monitoring

Adapters and network controllers based on the Intel® Ethernet Controller I350 (and later controllers) can display temperature data and automatically reduce the link speed if the controller temperature gets too hot.

NOTE: This feature is enabled and configured by the equipment manufacturer. It is not available on all adapters and network controllers. There are no user configurable settings.

Monitoring and Reporting

Temperature information is displayed on the Link tab in Intel® PROSet for Windows* Device Manger. There are three possible conditions:

• Temperature: Normal
  Indicates normal operation.
  
• Temperature: Overheated, Link Reduced
  Indicates that the device has reduced link speed to lower power consumption and heat.

  NOTE: Devices based on the Intel® X540 Ethernet Controller and Intel® 82599 10 Gigabit Ethernet Controller do not support link speed reduction.

• Temperature: Overheated, Adapter Stopped
  Indicates that the device is too hot and has stopped passing traffic so it is not damaged.

If either of the overheated events occurs, the device driver writes a message to the system event log.
