TEC1-12706 Peltier Module – Precision thermoelectric cooling, silent and uncompromising
Need to keep components cool without the hassle of noisy fans or complex cooling systems? The TEC1-12706 Peltier module uses pure semiconductor technology to provide cooling — there are no moving parts, no vibrations, and zero noise. The cold side drops significantly below ambient temperature, while the hot side dissipates the heat. All of this in a compact 40 × 40 mm footprint.
Note: Operating this module without a heatsink on the hot side will cause irreversible damage. Always install a suitable heat dissipator before powering the unit.
Why choose the TEC1-12706 module? (Key Benefits):
- 6A maximum current (vs 5A on the TEC1-12705) — delivers 60W of cooling power compared to 50W, providing a greater temperature differential between sides.
- Zero moving parts — completely silent operation with no vibrations and a significantly longer lifespan compared to mechanical cooling solutions.
- 2 thermal paste sachets included — ensures optimal thermal contact from the very first installation, saving you a trip to the shop.
- PWM control compatible — voltage can be adjusted between 0 and 15.2V, allowing for fine-tuned cooling power without sudden power drops.
- Wide thermal range: -30°C to +70°C — reliable performance in extreme conditions, from portable fridges to industrial applications.
Details and Performance
At 12V and 6A, this module generates a heat flux of up to 60W — perfect for cooling compact processors, CCD sensors, or laser cameras. The integrated thermoelectric semiconductors ensure consistent and repeatable heat transfer, with no degradation over time provided that mounting conditions are respected. By simply reversing the polarity, the module can also function as a precise heating element — the same component, two distinct functions.

Frequently Asked Questions
Is a heatsink mandatory for the TEC1-12706 Peltier module?
Yes, it is absolutely essential. Without a heatsink on the hot side, the temperature will quickly exceed the maximum limit, causing irreversible damage to the module within minutes. Always use a heatsink with a fan for high-power applications.
What is the actual difference compared to the TEC1-12705?
The TEC1-12706 supports 6A compared to 5A — providing 60W of cooling power versus 50W. The temperature differential between the sides is greater, which is critical for applications requiring sub-zero cooling or a steep thermal gradient.
Can it also function as a heating element?
Yes. By reversing the polarity of the power leads, the sides swap roles — the side that was cooling becomes the side that heats. It is the same module, offering dual-purpose utility.
Can I control the cooling power via PWM or variable voltage?
Yes. The module responds linearly to the voltage applied between 0 and 15.2V. Using a PWM controller or an adjustable power supply, you can precisely tune the power consumption and thermal intensity — highly useful for DIY thermostats or systems using Arduino and Raspberry Pi.
