I bought this water chiller for my small DWC setup since I wanted to keep my res temps under 68F. I’ve only had it a couple weeks but so far it’s working exactly as intended. The pipe clamps required a fair bit of tightening to keep them from leaking but other than that the installation was very straightforward. Noise levels are quite low. You basically set a range (within a few degrees) and once the max temp is reached it begins to cool until your set point is reached again. This is a passive cooler and does require an external pump to operate. I picked up a 400GPH pump which works perfectly. It has a titanium heat evaporator so hopefully it will last a long time.

This chiller works well. Zero issues.
