Spread Thermal Paste, Attach the Second Peltier and Connect it

Thinly spread a small amount of Arctic Silver over the top of the peltier you've already placed on the heatsink.

Place the other peltier (12709) on top of the existing one. Push it down a bit to assure good contact.

Important: The wires should be facing you and the red wire should be on your right.
