Abstract
In an example, an electronic device includes an electronic component with a temperature sensor to measure a first operating temperature of the electronic component at a first operating state having a first power value; and measure a second operating temperature of the electronic component at a second operating state having a second power value. The electronic device includes a controller to determine a first delta between the first operating temperature and an ambient temperature and determine a second delta between the second operating temperature and the ambient temperature. The controller is to determine a thermal resistance value and provide a notification when difference between a target thermal resistance value and the thermal resistance value exceeds a threshold.

A method comprising:
- measuring, by a temperature sensor associated with an electronic component disposed in a housing of an electronic device, a first operating temperature of the electronic component while the electronic component is at a first operating state;
- measuring, by the temperature sensor, a second operating temperature of the electronic component while the electronic component is at a second operating state;
- determining, by a controller comprising a processing resource and a non-transitory computer-readable medium, a first delta between the first operating temperature and an ambient temperature;
- determining, by the controller, a second delta between the second operating temperature and the ambient temperature;
- determining, by the controller, a thermal resistance value that is equal to a slope of a trend line on a graph associated with a first point corresponding to the second delta and the second operating state and a second point corresponding to the first delta and the first operating state;
- and
- providing, by the controller, a notification when a difference between a target thermal resistance value and the thermal resistance value exceeds a threshold.
