I got it, hooked it up, which was pretty simple considering I only had Red and Black wires to work with, and when I turned it on, it did exactly what I would hope it would do, cool, but not too cold because I am using it to heat/cool an environmentally controlled chamber to house rare cloud-forest orchids that require much colder and more humid conditions than could ever be expected in one's home. But, orchids aren't known to live in the Arctic so blasts of cold air wouldn't be good either so the gentle cooling and heating of this DIY heater/cooler is perfect for my application. That said, although the fans on the hot and cold side are well balanced in their respective air flow capacities to evenly extract the heated and cooled air enough to avoid thermal runaway on the hot-side leaking over to the cool side or causing excessive condensation buildup on the cold-side, I've ordered a 40x40x20 mm fan for the cool side to double the air flow on the cool side to increase the distribution of the chilled air because although the cold-side fan does do enough to prevent condensation, it doesn't flow enough air to keep the cold-side heatsink as "warm" as the hot-side heatsink is "cold" so I think much more cooler air can be extracted than is currently. Some have said that the Peltier chip is installed backward with the printed part number being on the hot side, I isolated the chip applying a low +5v just to test to the red wire and common on the black and the side with the smaller heat sink, the cold side, did indeed get cold so I don't know why people are saying the element is reversed when the manufacturer itself, Hebei, says this, "Lettered side of modules are the 'hot side'.” About the only critique I could make of the DIY kit is that the cold-side fan is too low in flow and also would be more effective, from a heat-transfer perspective, if it flows air into the heatsink instead of trying to draw it out. In an air-to-air heat exchanger that may be preferred but when forced air is used to extract "heat" from a surface, forcing air directly onto the surface is the most efficient. I'd buy it again and likely will when I need to build the next chamber. Review: Garbage - Ordered one thing and received the wrong Peltier. The fan is underpowered and useless. Reduced temp by 4 degrees C. Not impressed. Will be looking for a Japanese product and gladly pay more for something that works.

The fan is underpowered and useless. Reduced temp by 4 degrees C. Not impressed. Will be looking for a Japanese product and gladly pay more for something that works. Waste of money ### ⭐⭐⭐ Buyers be aware.... before purchasing..... *by D***N on August 19, 2020* The unit is well put together however when I checked the ohms something didn't seem right as part should have had a higher reading... which them forced me to take it apart to discover the cooling peltier is not a TEC1-12706 it is actually a TEC1-12705..... not that the unit will not cool as claimed but might take a bit longer and not hit large numbers in temp drop... Tec1-12705 = ΔT max. = 68°C, Qmax (ΔT =0) 57.0W Tec1-12706 = ΔT max. = 68°C, Qmax (ΔT =0) 63.0W Just a note that $27 built this way with an 06 is a great price... it should be more like $5-8 less since its an 05.... I ordered another one to confirm if the next one is 05 or as described 06... we shall see.... Also very terrible job on thermal pasting... half of peltier on both sides were not uniform but spotty.... If you take 10 minutes out of your life to at least put an even coat of paste this should do you justice for the price.... ## Frequently Bought Together - ESUMIC DC 12V DIY Thermoelectric Peltier Refrigeration Cooling System Kit Semiconductor Cooler Conduction Module + Radiator + Fan + TEC1-12706 - GDSTIME 92mm x 92mm x 25mm 90mm 3.6 Inches 12v Brushless Dc Cooling Fan 2 Pin --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/163546722-dc-12v-diy-thermoelectric-peltier-refrigeration-cooling-system-kit-semiconductor](https://www.desertcart.hr/products/163546722-dc-12v-diy-thermoelectric-peltier-refrigeration-cooling-system-kit-semiconductor) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-05-17*
