(2pcs) TEC1-12706 Heatsink Semiconductor Refrigeration Tablets 6A 12 Volt 60 Watt Thermoelectric Cooler Cooling Peltier Plate Module

I purchased this as a guess to repair a wine cooler purchased 8 years ago. It just happened to be a direct replacement. Yes some quality thermal paste and this works like a charm. The cold side is the one with the red wire on the right with the wires coming out the bottom. In my case the non printed side. This was a great price and is now performing perfectly. Great item and price plus I now have a spare if the lower unit fails in the future.

I ordered this product to replace a burned out TEC in a portable ice chest cooler. Cooling side is on bottom (unmarked side) when looking from top and positive red wire is on the right and black on left. After applying a small dab of thermo paste on each heat sink I screwed the assemble back together and both heat sinks got hot and cold on the appropriate sides within seconds of powering on. Power consumption is 3.3 amps @ 13.2vdc on power up.

Here’s the problem with these, and if you’re trying to get the as cold/warm as possible you should consider this: the most current I could pull with any of these at startup(no temperature gradient) is 4.2A at 12V, when it is supposed to go to 5A. This varies from plate to plate and it’s almost never consistently the same power on any of the plates. The reason that’s important is because if it doesn’t pull as much current, the temperature gradient across the two sides of the plate isn’t as high, which means you won’t get to really high or low temperatures. This is a good buy if you wanna stay at reasonable temperatures but if you’re really trying to boil something or freeze something it might not be the temperature that you want, it will vary, and it’s just because of the manufacturing process.Keep in mind though that I have tried multiple plates from different places and pretty much all the ones I’ve tried have the same story, varying power consumption, so it might just be that this is as good of a buy as any

These worked very well when I applied about 3.5v to them from a power supply. I couldn’t replicate that effect with batteries but that was probably due to not enough current (or not enough electronics knowledge). The design was solid and very clean and the temperature difference between the two sides was immediate and drastic once power was supplied.

Worked for only one day

Work well, remember to cool the hot side when reliable cooling is needed.The bigger the better heat sink when cooling the hot side.

Worked excellent on mu wine cooler.

I bought these to repair my wine cooler. It would be nice if they came with a designation of which side is cold and hot. At least someone posted in q&a which is which. So far the unit is working well and saved me from having to purchase a new one.
