2 pcs TEC1-12710 Thermoelectric Peltier Cooler 12V 100W 154Wmax

Works great for my projects. They are kinda fragile so be careful. Good build.

One worked great. I tested it with a massive Xeon heatsink and Delta 60 mm high CFM fan on the hot side and a small Chipset Heatsink the same LXW dimensions as the TEC. With an IR non-contact thermometer I measured up to 135 degrees F on the hot side and down to about 36 degrees F on the cold side in 75 degree ambient air. I didn't have adequate insulation and separation from the air on each side so these numbers quickly petered away. I power it with a 35 AH SLA Solar battery. The second module didn't perform as well. I don't remember the numbers but I think they were about 10 degrees different +/- on each side. Overall, I recommend these for any TEC project anyone has in the works.

Be certain this is what you want. These are thermo electic coolers, not thermo electic generators. Still, good value, arrived in perfect condition. No complaints.

Made two cloud chambers with these and a pair of tec1-12709 in a cascade. Both cascades get down below -35 Celsius. Arctic Silver-5 on one unit, Ceramique 2 on the other, both perform similarly.

does not work well

Work better for dropping the temp in my application for cooling my laser. But they do produce a good amount of head so be ready for that. First set I received where broken

Solid output, worked well for high power 12v fridge

Exactly what I wanted, and works as it says, good size, good price, will buy again.
