This allows for precise, solid-state cooling or heating with no moving parts. Simply apply 12V DC and attach a heatsink to the hot side for effective thermal management.\u003c\/p\u003e\n\n\u003ch4\u003eQ: What is the difference between TEC1-12705, TEC1-12706, and TEC1-12715?\u003c\/h4\u003e\n\u003cp\u003eA: The main differences are in cooling power and current draw. The TEC1-12705 offers up to 45W of cooling at 5A, making it ideal for light-duty or low-power applications. The TEC1-12706 delivers 60–72W at 4.3–4.6A, offering a good balance of efficiency and power. The TEC1-12715 is the most powerful at 134W and 15A, suitable for demanding cooling projects. All three share the same 40×40mm footprint for easy swapping.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Do I need a heatsink with this Peltier module?\u003c\/h4\u003e\n\u003cp\u003eA: Yes. A heatsink (and ideally a cooling fan) on the hot side of the module is essential. Without proper heat dissipation on the hot side, the module's performance will degrade significantly and the module could be damaged. We recommend thermally conductive paste between the module and heatsink surfaces for best results.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Can this module be used for heating as well as cooling?\u003c\/h4\u003e\n\u003cp\u003eA: Yes. By reversing the polarity of the DC power supply, the cold and hot sides swap, turning the module into a compact heater. This makes TEC modules very versatile for temperature-control applications that require both heating and cooling modes.\u003c\/p\u003e\n\n\u003cscript type=\"application\/ld+json\"\u003e{\"@context\": \"https:\/\/schema.org\", \"@type\": \"FAQPage\", \"mainEntity\": [{\"@type\": \"Question\", \"name\": \"What is a Peltier thermoelectric cooler module and how does it work?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"A Peltier thermoelectric cooler (TEC) module uses the Peltier effect — when DC current flows through two dissimilar semiconductor materials, one side absorbs heat (becomes cold) and the other side dissipates heat (becomes hot).
