KOOBOOK1Set 12V Thermoelectric Peltier Cooler Refrigeration Cooling Fan System Heatsink DIY Kit

I used this product with the water block connected to a sink, to cool the heatsink and blow cold air in an insulated container. So far testing outside of the container allowed me to get the heat sink to as low as -13 degrees C, in ambient air temperature of 20C.I would recommend using a higher quality thermal paste than the one provided. I used a high powered TEC-12715 with mine, so I would expect lower if using a TEC rated for lower amperage.I found the fan in both orientations to detract from the heatsinks ability to stay cold. Since it was in open air it was serving no purpose at the time. With a thermal imaging camera I saw the fans produced some heat so keep that in mine when using. Overall, this product provides a cost effective solution to TEC hobbyists, but could benefit from a higher quality fan.

You need to understand that you do NOT get a Peltier module with this kit. The description is a bit misleading, as there is nothing in the kit that is "thermoelectric" and nothing that "refrigerates". What you do get, is a sturdy heat sink, a small 12Vdc fan, a water heat exchange block, a bottom clamp bar, and some basic hardware. You assemble it yourself, with your own heat sink compound. It is suitable for a 12706 sized module. Saves buying all of the parts separately, except of course, the actual module.

This has all the parts, minus chip, to build a water cooled peltier system. Most pre-made units come with the 12706 chip (6A). I chose the 12710 chip (10A) for better cooling. This kit was very low cost and worked well. The cooling module runs hot and a good amount of water throughput from the lab sink is a good idea. I used an aquatic pump and ice in a large beaker. I was able to reach around 5 deg C in a 15L insulated chamber with this combination.

Let me be clear, since the seller isn't. This does not contain a peltier cooling element, this is only the resources to cool one down. I don't think this is a good deal as I could get all the components separate for only twice as much with 4* the yield. Not to mention the fact there is no pump, the heatsink is poorly assembled, and it came in a bag that provided no protection during transit, this the bent fin. no way I could recommend this
