This is a different situation altogether. In a straight waterblock loop, the stored energy in the bp at equalibrium will determine die temp. Higher flow lowers this stored energy at equalibrium, effecting die temp accordingly.

This is certainly true. However, there is little, if any, benefit to being concerned with the quantity of the stored energy. As Cathar pointed out, the relevant information is inherent in knowing the temperature gradient. Limiting the discussion to the amount of energy transfer per unit time (power) and temperature gradients covers the relevant issues and IMO reduces confusion.

The "efficiency" of the TEC is only relevant with a context of hotside temperature and desired coldside temperature.
Why use a TEC and two TIM joints to acheive 'max TEC efficiency' and dT of zero? Discussing "efficiency" of a TEC without reference to specific hot side and coldside temperatures is fairly meaningless IMO.
