Here's a tip to optimize the cooling. We found that at a certain point the heatsink attracts moisture and will eventually ice up if it gets cold enough, otherwise it just gets really wet. As soon as it does this the cooling effect is hindered. Here in australia we have things called a...

A friend and I have spend the last couple of years messing around with peltiers and I can confirm that they are certainly not capable of cooling much below ambient without going to a fair amount of effort to optimize them with large heat sinks and preferably water cooling blocks and radiators...
