home made Peltier cooler questions

Greetings, I took my nearly finished home made cooler out tonight to see if the bench test temp drop was the same when taking darks.
It seems not to have made much difference to the EXIF temperature so far, and I am wondering if the fact that I didn't do the aluminium box/washer to tripod mount hole metal connection thingy that Gary Honis does with his mod would make the difference. My inside box sensor is dropping in temperature but the EXIF temp has stayed the same. You can see by the picture that it is very much a prototype, ungainly thing that it is. It is also quite heavy with the two fans plus large heat sink.
In forty minutes got a 5 degree drop below starting temperature but as I said before the EXIF has hovered around 24-25'c which was the same as when it started. I assume the plastic camera body is insulating it better than I thought.
Any tips?
