Review on 💧 DIYhz 8-Pipe Water Cooling Radiator: High-Performance Aluminum Heat Exchanger for PC Laser Cooling System, Black - 80mm, DC12V by Danny Poulin

I am using this product to cool my K40 laser cutter and it seems to be working 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.
