OCCT includes a monitoring engine that provides complete readings of machine internal temperatures, voltages and fan speeds, and displays them in both real-time and in-process graphs.
The graphs show a second line showing CPU and FPS usage during OCCT test. CPU usage is instantaneous, and not average from the beginning of the test, as was the case in the first releases of the program. The modern version has 5 different options, descriptions of which are at the end of the changelog.
