Cool down very quickly! Review: Generates *lots* of heat on the hot side - I bought a heat sink off of desertcart 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. ## Features - TEC1-12706 40*40MM Semiconductor Refrigeration Plates - The side printed with TEC1-12706 is the cooling side, another is the heating side. - Preparation items: TEC1-12706 Cooling Plates+ Cooling Radiator + Thermal Grease + Thermal Insulation Pad + Power Supply - Note: Please make sure you have installed with a heat radiator on the heating side. Otherwise the overheating will burn it out. When you installing the radiator, make sure to scribble some thermal grease on the surface. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00M1PM7H6 | | Best Sellers Rank | #82 in Heatsinks | | Brand | HiLetgo | | Brand Name | HiLetgo | | Cooler Heatsink Compatibility | CPU coolers with Chassis Mount mechanism | | Cooler Heatsink Material | Aluminum | | Customer Reviews | 4.3 out of 5 stars 562 Reviews | | Item Dimensions L x W x H | 1.57"L x 1.57"W x 0.14"H | | Item Weight | 0.02 kg | | Manufacturer | HiLetgo | | Model | 3-01-0553 | | Mounting Type | Chassis Mount | | Number of Items | 2 | | Part Number | 3-01-0553 | | Product Dimensions | 1.57"L x 1.57"W x 0.14"H | | UPC | 702082657218 | ## Product Details - **Brand:** HiLetgo - **Cooler Heatsink Compatibility:** CPU coolers with Chassis Mount mechanism - **Cooler Heatsink Material:** Aluminum - **Item Weight:** 0.02 kg - **Product Dimensions:** 1.57"L x 1.57"W x 0.14"H ## Images ![HiLetgo 2pcs TEC1-12706 Semiconductor Refrigeration Tablets TEC1-12706 12V 6A Heatsink Thermoelectric Cooler Cooling Peltier Plate Module 40x40MM - Image 1](https://m.media-amazon.com/images/I/51ZT6CvjfdL.jpg) ## Available Options This product comes in different **Size** options. ## Questions & Answers **Q: How much electricity will this module produce with just heat of my hand and ice? im trying to make a body heat powered led light. any suggestions?** A: Negligible. It is not intended to produce electricity, it is intended for cooling. You may want to check out the SP 1848, that module is optimized for electricity generation, but hand heat will not be enough to power it. **Q: witch is the cold side?** A: If you connect positive to red and negative to black, then the cold wide will be the side with the printed writing. But you can flip polarity and the cold/hot sides will flip. **Q: What is the watage?** A: Approximately 85 watts if used at voltage of 14 volts. The watts used go down if you apply less voltage. You may also be interested in TEC1-12715 as it is double the watts of this unit. **Q: What is a good way to measure the current flowing through the Peltier semiconductor module when supplied with 12V?** A: The module must be attached to a very good heat sink, and then you can just a multimeter connected inline of the circuit, set on Amps. You must have a good heatsink attached because if not, the current flow will stop as the chip will reach stasis. The other option is to use AC current, that's the only way to measure the current without a heatsink attached. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Cool down very quickly! *by J***L on October 25, 2025* Amazing cooling part!
