Lsgoodcare 120W Semiconductor Refrigeration Cooler Kit DIY Peltier Cooler 12V TEC1-12706 Peltier Heatsink Module kit Thermoelectric Cooler Peltier Cooling System for DIY Car Electronic Refrigerator

I have used peltier modules before so knew what to expect.The advertising does paint a bit of a glowing picture.The whole module is quite well built and when used within normal ambient temperatures achieved a reasonable drop in temperature with flowing water. I rigged it up to a temperature controlled system, the fans were kept running with the peltier modules being controlled. There was a lot of lag but eventually settled down to a reasonable amount of control.Remember you need a fairly hefty power supply, 12v 9A minimum. These modules actually work at 14v for maximum temperature difference between the plates but sourcing a 14v supply is not so easy.Price wise I am very happy. Each peltier module would cost about £6 so 2 of those plus 2 fans plus the metal work. For me it was a no brainer, not only price wise but time saving not having to build it.

This is a compact device which seems well made. The water tank has inlet and outlet to cool the water you pump through it.Connection is easy enough, although you need a decent supply. Mine draws over 100W (around 8.6A), although it's more efficient at just over 12V where the current goes down. Most will keep it at 12V though.The Peltier unit does it's job with the fans taking the heat away good enough for light use. You'll do well to have bigger fans for more efficient operation. I put an old PC cooling fan and heatsink on it to improve matters.I've managed to go from 5C drop using the current fans to 15C drop using bugger fans/heatsink, so the unit is capable, just undercooled.
