Intel® Ethernet Adapters and Devices User Guide
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.
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 Manager or in the Adapter Information panel in Intel® PROSet Adapter Configuration Utility (Intel® PROSet ACU). 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.
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 occur, the device driver writes a message to the system event log.
