what is the height of the smaller heat sink. I will be mounting this through something to keep the hot and cold sides separate through it?

The smaller heatsink is 28mm, and with the fan it’s 36mm.

Could you make this cool an outdoor pet house? What would be needed besides this to do that?

It could work as a heater but not as cold a/c. This peltier module has two sides, the big fan gives you 80% hot air, and the tiny side 20 and if that 20 goes into a non air sealed container you’ll waste your money.. good luck..

How many degrees does it cool below ambient temperature? It says 5 to 6ﾟ in description. Is that it?

We did an experiment. After 2.5 minutes, the temperature dropped 10F, and after 10 minutes, the temperature was 13.7F lower than surrounding temperature. With time goes by, the temperature tend to stabilize. However, it also depends on the insulation around the Peltier. I hope that answered your question.

what power supply should I use. any 12v? does the 12v power supply need a minimum number of amps? thanks

I believe its a max of 6a @ 12v assuming all the heat is being removed
