Isn't it true that TEC's have a sharp curve after like 75% max voltage? And that using the max voltage creates extra heat with little performance gain? If it's true, then maybe that extra heat isn't getting dissapated and is going back into the cold side, keeping it from getting as cold as it could.
Just a thought.

Not quite.
Above 80% of the voltage, the heat transferred increases very little, so there just isn't much point. The extra power applied still needs to be dissipated, which will increase the water temp, essentially unecessarily.
