Back to the Layered Cocktail Analogy
If the layer slide in is warmer than 300 units but colder than 400 units, there is less net flux down from the 400 block, but about the same net flux into the lower block. The 400 block can cool more efficiently upwards. The total energy of the "system" increases by whatever energy is transferred in by the slide layer. If the slide layer has lower thermal mass, it would quickly "temper" to the average energy of the upper and lower blocks. If the slide layer has high thermal mass, "tempering" will take longer and if the layer is an actual flow, heat will be transported elsewhere.
