I think in practice you are going to need to mount the 5680 to an
aluminum plate at least twice the size of the 5680 and then keep a
moderate airflow over the top and bottom.  Perhaps mount the  plate
using standoffs.   It's clear to me from seeing all those screws that
the 5680 needs to be firmly connected to some kind of heat sink even
it only a large plate.

Yes you pretty much have to calibrate the 5680.   But what do you mean
"if that changes"?  the 5680 will drift away from any calibration.
