Son económicas y funcionan a la perfección. No puedo evitar mencionar lo bien que me siento por haberlas adquirido a un precio tan accesible. ¡Definitivamente superaron mis expectativas! Además de su rendimiento, me complace el hecho de que son una opción amigable con el medio ambiente, ya que su vida útil prolongada significa que no tendré que desechar baterías con tanta frecuencia. ### ⭐⭐⭐⭐⭐ EXCELENT *by J***. on April 3, 2024* EXCELENT ### ⭐⭐⭐ These should be de-rated to 70% of the advertised Amps. *Updated 2x* *by C***T on July 15, 2023* CONCLUSION: Make your purchase based on how many watts you think you need, and then de-rate the modules by .7. (15A rated times .7 = 10.5A) I purchased two sets of 6 of the 12708 modules. They all barely cooled. I was baffled! At first I blamed my design and doubled my heat sink surface area. Still did not work well. Then I did a current draw test on each unit (all 12 of them). The results: 3.0A falling quickly to 2.6A at 14.4V. These are supposed to be 8 amp modules. The label on the modules was 12708, and specified as 8 amps. Clearly they were not working properly. I was able to return one set. These are actually (defective? or) under performing modules. DO NOT TRUST what you receive to perform at specification. Test it fully before installing it!!! UPDATE #1: I purchased 12715 modules. They tested at 8.5 amps at 14.4V. So the trend continues; they greatly under perform below specifications. Note: these things need to loose all the heat they move to cool effectively, so mate the HOT side to as much of a dissipation surface with fans as you can. FINAL UPDATE: I now have a working system. 6 of the 12715 modules initially draw 64 Amps at 13.8V at 'turn-on". This quickly falls back to 50A at 13.8V. That means that each module is drawing 10.66A initial and 8.33A steady working current. This equals +/- 115 Watts per unit. Way, Way below specification. ## Frequently Bought Together - UMLIFE 6PCS TEC1-12708 TEC Thermoelectric Heatsink Cooler Cooling Peltier Plate Module 40x40mm - DIYhz Aluminum Water Cooling Block, Liquid Water Cooler Heat Sink System for PC Computer CPU Graphics Radiator Heatsink Endothermic Head Silver 2pcs(40mm x 200mm x 12mm) - GENNEL G109 10gram Thermal Conductive Glue, Heatsink Silicone Glue, Thermal Plaster, Silicone Viscous Adhesive Compound for LED GPU MOSFET Printer Chipset IC High Performance --- ## 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.jp/products/373461190-6pcs-tec1-12708-tec-thermoelectric-heatsink-cooler-cooling-peltier-plate](https://www.desertcart.jp/products/373461190-6pcs-tec1-12708-tec-thermoelectric-heatsink-cooler-cooling-peltier-plate) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-08-15*
