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

The radiator exceeded my expectations. I ordered a DIYhz water-cooled computer heatsink, a 12-tube thick copper heat exchanger. The price was definitely okay compared to the high-end brands available. I contacted the seller for product info to confirm it was copper and I received a quick reply yes it is copper and when it arrived it was intact with copper innards. I actually had to run a few good cycles of a light cleaning vinegar and hot distilled water threw it out. I was able to remove many…

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.

Not a very good heatsink. In no case were all chambers filled with liquid. My flow dropped significantly as if there was a blockage. I bet there were a lot of bad solder joints in the heatsink. No additional connections for access or drainage. You get what you pay for.

Radiator works great. Installs in minutes. No leaks at the connection. I use two of these to chill the water for my 40 watt CO2 laser. I see no increase in water temperature when using a laser. This means that the radiators do their job perfectly. I use two 120mm fans with heatsinks.
