Abstract: In an example implementation according to aspects of the present disclosure, a computing device and computer readable media to receive a temperature, operating speed, maximum operating speed, and utilization rate of a processor. A processor performance metric may be calculated based on the operating speed, maximum operating speed, and utilization rate. The processor performance metric and temperature may be used to retrieve a value in a thermal mapping. The value in the thermal mapping may be compared against a threshold to determine if a processor thermal metric event has occurred. An indication to the user may be presented in the event of a thermal metric event.
