Review on DIYhz Water Cooling Radiator for PC, 8 Pipe Aluminum Heat Exchanger Liquid Cooler G1/4 Thread Heat Row Sink 80mm, CPU Laser Water Cool System DC12V Black by Paul Weakland

I use this product to cool my K40 laser cutter and it works fine. I paired it with two Arctic 120mm fans and the included screws fit perfectly. No leaking with included hose. The K40 laser comes with a much smaller diameter tube, but being silicone it can be pulled over pre-installed barbs. The only downside is the fact that it's aluminum. So if there is copper or brass in the cooling circuit, it can potentially accelerate corrosion.
