Ok, well I figured I may as well get started on walking through Project Vortex. It's going to be a long slog because of the amount of time have to work on it, however if I get it in then I'll be inclined to finish it Project Vortex was born the day I discovered that with an Eheim pump and old CD spindle, you could make a persistent vortex which looked the mutts nuts. It then occured to me how awesome this would look inside a case. Here's a little prototype I knocked up. As you can see, the vortex effect is quite visually impressive. You need to have the water coming in at an angle to create the turbulence which will start the vortex off. One problem it suffered from was the fact that it would eventually work it's way into the pump and draw air into the impeller. As we all know, air in your watercooling rig is not good, so moving a piece of tube into the res meant that the vortex would stop at the tube and stay away from the pump. A natural progression from that is to move the pump further away so that the vortex is free to go all the way down to the bottom of the res. As we need to not only house the res somewhere, but we want it to be big and impressive in order to look good, I'm going to be using a Lian Li PC-71 for this project. which has enough space in there to house it all. That's the starters, More later on..
