This is a thermo-electric chip (TEC) with an air cooled copper heat sink salvaged from a computer on top and a length of 1.5" copper pipe filled with antifreeze on the bottom. It is stuck together with thermal epoxy.

The cold side of the chip quickly cools the copper pipe.
The "hot" air that passes the cooling fins is about 75-77 degrees. The fan is .27 amps and moves a lot of air. I tried a quieter fan, but it didn't cool the hot side of the TEC as effectively, which is the key to getting the maximum cooling efficiency from a TEC.
It is about 65 degrees in my shop.
