(if used correctly)

There are many TEC1-12706's that are 'fake' in the sense that they have less thermoelectric material and are actually 2 or 3 amp units with a 6 print on them. We test each batch and have taken a lot of money and effort to obtain and keep in stock the best (for the price) 12706's that pull the correct amperage and pump more joules than the competition. That is why the price may be a little higher. I can honestly say this is one of the best Peltiers for the price you could get. That said everyone's needs are different, and if you are not sure if a 12706 is appropriate for your needs, send us a message and we'll help you sort it out. 

You can always run these at lower voltages for higher efficiency - as the current decreases, the coefficient of performance increases. At 12 volts the ΔT is almost 60°C. As you decrease the voltage and current draw, ΔT will decrease, but even at 1 volt there is a noticeable temperature difference, accompanied by the most efficient heat pumping you will find for this price.

Take your temperature control needs to a new level with solid-state.

These solid state devices are finding their ways into many creative applications. At Cold&Colder, we use them for custom-built server cabinet cooling. Since we use them ourselves, we can offer you advice on your application needs. Any questions are welcome. Bulk orders welcome, we have over 1,000 pcs in stock.
