That's because temperature as it's classically defined has a coordinate asymptote (at 0K). The fix used in quantum thermodynamics is to talk about thermodynamic beta which is the inverse of temperature, where heat flows from a low thermodynamic beta to a higher. That fixes the coordinate issue and you can cross easily from the classically to the quantum.
