KKmoon DIY Kit Thermoelectric Peltier Cooler Refrigeration Cooling System Heat Sink Conduction Module + Fan + TEC1-12706

The TEC itself works fine at 12V 5A, however one thing wasn't immediately clear to us which we feel we should point out:- The heat sink shown in the picture is for the cold side of the TEC only. The liquid heat exchanger side is the hot side. If you attempt to cool the liquid side, the heatsink and fan will overheat. They are not large enough to remove all of the heat. Even running at 2A, the heatsink is woefully undersized. -This is likely the cause of many of the negative reviews. If you are trying to make your heatsink/fan cold, this works great. If you are using it the other way around, look for something with a much larger heat sink, or build it yourself.

All the parts to get started including thermal grease.No Assembly instructions, but assembly was easy. Nothing fragile. Small Phillips head screwdriver is the only tool needed.Fan could be bigger and more powerful. Ran everything on 12v at 3 amps from BMOUO 12V 30A DC power supply (Amazon, $20 )Felt plenty of cold or heat. Just loosen the screws and flip the TEC over. Never reverse voltage or current.Fan wires have connector, TEC 12706 does not have a connector. Just wire with solder or "tinned" Also the fan wires are a different length.Recommend 12 year olds and up as the TEC can get pretty hot pretty fast.Good for school, learning or just fun.

Great kit. Water cooling certainly works better than the heat sink and fan alone. Would recommend getting additional thermal paste as the packet of paste that came with was very small.

I had to buy the holes, cooler liquid and radiator. It doesnt cool enough for a small cage im using. The heat over takes the cool. All it does it melts the ice and sweats. Even when i bought a separate fan for the radiator just run and doesnt even cool down. Wasted money cant get it back. So now i just have these sitting around. Waste of money. I would definitely would exchange this with the bigger fan and heatsink. Rather than the waterblock method.

The kit was handy to get, but the fan and heat sink are too small for the Peltier device - wish it was maybe 25% larger to cool the hot side down more. Unknown water cooling block configuration internally - would have been good to know the type: posts, fins, or what.

Fan doesn't create cold air, but the use is limited to cold electronic things like CPU or computer/Arduino heatsinks (so the fan is probably doesn't needed). Not very valuable for its price, since the peltier modules are cheaper.

I was forced to give a star rating to post this review, I would give this ZERO starsAll can get this to do is produce heat on both sides.Very poor instructionsWhen fan first plugged in it would not runI would not buy this product and it looks like there is no way to return it.And smell of chemicals): ):

Lack of any technical data or engineering information. It is functional, but is not recommend to people without knowledge in electronics

Die Lüfter und Kühlrippen sind viel zu klein dimensioniert um die große Verlustleistung der Peltierelemente abzuführen. Mit dem dargestellten Setup (CPU Lüfter aus der Restekiste statt Originalzubehör) funktioniert die Kühlung einwandfrei.

TOP!!

Lüfter sind für die Leistung der Peltier Elemente viel zu klein
