>> the primary method of evaporation of nectar in the hive consists of placing small droplets in cells, maximizing their surface area. 
>> ... I place all available supers on the hive, at least 3 or 4 medium depth supers. This gives them plenty of space to disperse the nectar. 


The dichotomy here is the need to keep brood warm and moist, versus the need to move air across all those open cells with nectar in them.
We see the ranks of fanning bees on the bottom board, yet no one asks how all that fanned air impacts the brood.  The nurse bees are (apparently) somehow protecting the brood cells, keeping them "environmentally stable".  Or perhaps they just increase the frequency of feeding, to make sure that brood food does not dry up as quickly as the nectar, and it is the brood food that provides the stability within the cell, a tiny little thermal mass with a consistent moisture.
