Etymology: "Overtemperature" is a plain formation: the prefix "over-", meaning excessive or beyond a limit, attached to "temperature", which comes from Latin "temperatura", a noun from "temperare", to mix in due proportion or to moderate. The base word has the older sense of a proper blending or balance, which is why "temperature" can describe how hot or cold something is measured against a standard. Adding "over-" flips that idea: rather than a balanced state, the term names a condition where heat has passed the permitted ceiling. The word is mainly used in technical and engineering contexts, where it describes a component, machine or system running hotter than its rated maximum. Because the meaning is fully transparent from its parts, it needs no special history beyond this construction.
