NEW PRODUCT – Peltier Thermo-Electric Cooler Module+Heatsink Assembly – 12V 5A. This is for people who just want to get cold fast. The 12V Peltier module is mounted onto a 12V heatsink and fan assembly with thermal paste and an aluminum clamp. Simply connect to 12V 5A+ power supply and you will see frost appear on the aluminum plate within a minute. This assembly comes with the best Peltier we could get, so it can get even colder than the stand-alone module we stock, but we think the price is worth it. Just sitting on our desk it got down to -3.6°C, nice and frosty! Comes with the Peltier, heatsink, fan all assembled. You’ll need a power supply to power it, we suggest our 12V 5A wall adapter. We show a temperature meter in a photo but that’s not included, its just to show you how cold it gets.

Sorry, the comment form is closed at this time.
Now place it right side up so that the fan has good in flow and can cool the heat sink with exhaust in both directions and place the thermocouple/RTD whatever temp sensor you have firmly down on the cold plate using some thermal paste and I bet that temperature will be quite a bit lower.
Users should make use of the holes in the corners at the root of the outer most fins – tap into those or just use self-tapping screws and mount the whole thing so that there is some gap under the fan.
Awesome new product! Good job Adafruit!
