This cooling system produces too much heat, and the cooling fans are very weak. 2 of the fans don't work out of the box. I replaced with stronger fans but still not sufficient. It raises the temperature of the liquid that it supposes to cool about 5F. Read more

420, Hydro growers here I have a 1xpeltier chip module going right now to chil my 85L of hydro water down to 16C. Let me tell you, these peltiers really do cool water down, but it's better to have it on a closed loop system and going through a wort chiller suspended in your resevoir. This way the heat reansfer is radiant instead of just dumping the chilled water back in to the warmer water. I ordered this unit 5 days ago and it arrived. It looks really really well made, the ONLY complaint i have anout it would be that the FANS on the heatsink look to be rather UNDERPOWERED. I will have to try it out and see for sure, but thats just based on speculation alone so who knows. Read more

The water interfaces of the radiator are so gentle so it was broken easily. Ok, I made thread inside the holes. After the water commutation it became leaking in welding or pressing joints. Ok, I fixed the leaks. But then when all the commutation was done it appeared to heat instead of cool. I changed the polarity but it is not cooling efficiently. Highly not recommend Read more
