I suspect the cold side would have been much better if it was actually boxed in as the ambient was flowing around the sink. I will get it boxed in foam for the next test, then work out how to attach the cold side to my cold finger from the laptop.
That looks awfully like the one I bought. Good luck with it.
Here's a couple of shots of my final build. It's only waiting for the TEC (en route from the states) and a power supply for the camera (en route from China) and a T-Ring and DSUSB (en route from Bintel). As you can see, there's more still coming than here.
