OCCT is a software program for checking the stability of a PC by performing stress-tests upon the PC's CPU. In general, this means sending large quantities of highly complex instructions to the CPU in an unending stream, which is contrary to typical computer programs which typically won't be constantly doing work through the CPU. As a result, the electrical components of the CPU will heat up faster, and any flaws or stress failures in the CPU design can be shown much faster.
