That's true in general, but if the time step is small enough the temperature shouldn't keep increasing.  Initially there is no gradient through the thickness to conduct the heat so the enthalpy of the element adjacent to the surface determines the temperature.  If the element is small the enthalpy will be less.  But if the time step is also small, that will reduce the amount of heat and keep the temperature from becoming artificially large.
