Tom, I am not sure what disconnecting all ground pins but one would do to the sensor. While in theory it should be the same, for example those pins may be used internally to reduce the noise. There must be a reason why they are all ground pins and not NC (not connected) pins. But again, that is just a guess unless someone compares the sensor performance.

Brendan, it sounds like you are doing the right thing. What happens if you remove the small heatsink from the cold side? How could would it get without a heat load? I would expect for it to get covered in ice quickly.
