I used a 12V 6amp PWM controller to throttle my Peltier, in the cold finger coolers I built, you can buy them on eBay for about $5. I suggest a temperature sensor with remote cabled probe that can be inserted into the sensor area. A small plastic project box can house both the PWM and temp display head.
You will need a heat sink/fan to exhaust heat from the hot side of the Peltier device.Little Laptop scroll fans (ebay) can do the job. Obviously the bigger the heat sink and fan combo the better in terms of Delta T.
If you do not exhaust the heat from the Peltier hot side you will cook it pretty quickly.
