Good answer from Physics SE on why there's no upper limit to temperature: https://physics.stackexchange.com/questions/1775/why-is-there-no-absolute-maximum-temp

  Would also add to this that ideas about what "temperature" means change when you are switching between equilibrium and nonequilibrium thermodynamics. In nonequilibrium thermodynamics a bunch of your equations go out the window, like the Boltzmann distribution, and all of the rules built on top of that which are many.
