Let's suggest whe are at the half way point and employing generous amounts of hot-melt glue to not only fix delivery-tubes to delivery-holes but also (to) form an insulative barrier/coolant chamber between the board and the raised CCD sensor chip - proper.
This may or may not be such a great idea as the chiller fluid needs "elbow room" to evaporate - to affect max cooling. As it is - it's a bit confined and the chiller medium is exiting the back surface exit-hole seemingly thermally unaffected. It may well turn out that the best cooling is achieved via a thin trickle (of fluid) as opposed to a blast of gas. The fluid can be encouraged out of the can under low flow rate conditions and by keeping the can on it's side. Stay tuned .. we're heading into the clubhouse turn.

This is the power supply portion primarily for two banks of LED illuminators - which I have disconnected for our purposes. I'm confident that what appears as the main logic board has now been down-sized onto a pin-head : )

I'm hoping this all works once I fire it up (oops .. 'cryo' it up) .. poor camera never imagined it would be put through these paces - i.e. all manner of home-spun torture. My earlier attempt at installing a peltier cooler turned into an abject peltier cooling fail. The signal was 4 times noisier. This, most likely as a result of using heat-sink compound as the thermal couplant < the stuff is conductive (zinc oxide) and shorted all the traces .. doh! Suffice to suggest it was an "on-off test" (there was an image - albeit snowy) and that I have yet to energize the camera - since.
I cleaned out all the misguided zinc oxide - therefore: unforseen circumstances not-withstanding .. we should see 'first dark' in the near future.
