# 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 10 Gigabit 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.
