Most of the components have a boiling/melting point of more than that. So I say no biggie.
The maximum operating temperature has nothing to do with melting points of the components and everything to do with the fact that a higher temperature changes the physics involved, such as the capacitance, resistance, and so forth of components. Not to mention of course the increased expansion/contraction that occurs between the metal conducting and non-metal insulating components that can cause traces to develop hairline fractures. In the case of a CPU, the change in resistance and other properties of the various components both shortens the lifespan as well as causing errors.
Secondly, running a computer for a shorter time at a high temperature stably is no indication that you can do so for an increased period of time. my old K6-2 processor has a rated maximum of (I believe) 68-75 degrees, but due to it having a thermal pad that time forgot it would often approach 85 to 90 degrees celsius. Was it stable? well, yes, for the most part. But that's hardly any indication of endurance at those temperatures, it just means it can handle them for a short time.
a Human being can live for 3 minutes without oxygen. by your logic, depriving a person of oxygen for 2 minutes, we can come to the conclusion that they can survive indefinitely without it.
Short term effects are almost always entirely different from long-term effects. Drug addicts learn this the hard way.
