HiLetgo 2pcs TEC1-12706 Semiconductor Refrigeration Tablets TEC1-12706 12V 6A Heatsink Thermoelectric Cooler Cooling Peltier Plate Module 40x40MM

Works great! Wine fridge is back to work!

Amazing cooling part! Cool down very quickly!

Device worked as expected. Fixed a small cooling cat feeder.

One of the modules arrived dead sadly, no point in returning because its unfixable not worth wasting resources during shipping, definitely a good price for the product compared to other listings. Not a 6 AMP Module but I don't mind it was to be expected for the price. I think they meant to list it as 3 amps per module or maybe the modules have to have high performance cooling to achieve such power draw. I was using it too cool down my GPU, RAM & CPU but it damaged my computer parts after realizing that one of the modules was dead. Definitely was fun for my prototype. Learned a lot about Peltier Modules when using in practical application.

I bought a heat sink off of Amazon that said it was for this unit as it matched the 40mmx40mm footprint and had numerous fins (but no fan). However, within about 20 seconds of hooking the Peltier unit to a 12V, 5A power supply, both sides of the Peltier were hot: the "cool" side about 10 degrees F above ambient and I almost burned my hand on the heat sink on the hot side. I found a 10W power supply (12V, 0.85A) and it worked pretty well for my application: it cooled the cool side about 10-15 degrees F below ambient and the passive heat sink mentioned above with a 5V computer case fan managed to keep it at that temp until the ambient got above approximately 105F...then it can't quite move the heat off the hot side fast enough. One thing to correct from other reviews: these Peltiers will *not* work with any voltage below 12V. You can control the amount of cooling they provide on the cool side (and thus the heat they generate on the hot side) by limiting the current (i.e. the number of amps) to the Peltier. If you do more than 10W of power to the Peltier, I'd recommend a computer CPU heat sink with a fan that can provide at least 90W of cooling.

Great stuff, got it working with 6A (70W) and 5A (60W) for a parallel stack. Top one Direct to air cooling the 2nd inbetween liquid to liquid.. went on Thanksgiving vacation after testing these out an came home and continued my project. And they short circuited immediately an filled my room with smoke an threw my brand new 60A 12V/24V power supply into short circuit protection mode... these garbage ass. Out of four only one worked an that shorted out after only not even an hour of running time total. Ordered different ones at 15A, screw these garbage manufacturers this seller aint getting anymore of money. I managed to get hot side to sit at 28C to 30C on the exhaust too so im pissed i made it this far an cheap china garbage kicks me in the face an i lost $100 in supplies now as thermal glue does not come undone.. i hate this seller..

One works from the twin pack and looks like this happens frequently based on other comments. The first was installed and was all hot. The second has worked well.

Perfect for my project
