Testing the liquid-cooled heat sink… I’m using a 290gph submersible pump designed for back yard fountains and water features. It doesn’t produce a lot of pressure, but it should be enough for this project. The heat sink design is the same as was detailed in previous posts. I just finally had time to solder it all together. It seems to work very well. However it will need a tube on the “outlet” side, as well as a pair of really small hose clamps. The pvc tubing isn’t quite tight enough to completely seal up on its own.
