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

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.

Works well

I have a portable cooler/heater that stopped cooling/heating. It was $128 new. I was going to throw it out but decided to try to fix it first. I took it apart and found this device inside. I bought this set of two and repaired the cooler/heater! For $8.49 for two, it's a huge bargain not to have to throw out the cooler/heater! Beware, I tested the device before installation. The hot side gets hot so fast I almost burned my finger! It's hot in seconds.

I bought these to replace a dead unit on my wood stover fan. It kicks on at a low temperature and spins just as fast as the old unit.

Works great! Wine fridge is back to work!

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..

Years ago these little thermoelectric doohickies were quite a bit of money, but for the price of the HiLetGo's I thought I'd try them for my old Ecofan. Only issue I had was that the 40mm size was a smidge too large and I had to remove some side wings on the unit and also use smaller diameter screws to hold the top assembly to the base. I smoodged a fair bit of thermal paste on both sides and got it assembled and it works which is the main thing. If and when this one dies, I'll look for a slightly smaller unit like the oem. But for now I'm a happy camper.

Perfect for my project

Lo utilice para repuesto a una cava . Buena calidad

Works pretty well good packaging all good quality

Good

They take only 2.5 amps it means they they not real 12706 , if you really need 6A peltier dont buy it

Lo utilize para sustituir la celda peltier de un enfriador de mesa Mabe y le funcionó bien
