Self-generated thermal stress evaluation concepts are described. In one embodiment, a system includes a computing device, a cooling system, such as fans, that draws heat away from the computing device, and a management controller. The management controller can sense a temperature in the computing device and compare it against a temperature profile. The temperature profile can specify one or more target temperatures in the computing device over time. Based on the comparison, the management controller can adjust a cooling capacity of the cooling system. The adjustment to the cooling capacity can be achieved by reducing the speed of the fans, for example, to raise the temperature in the computing device. Processing tasks can also be executed in the computing device and, in response to the detection of an error in the computing device, the management controller can record the error and a profile for the error for further evaluation.
