After many times opening and disassembling the Cube to get to know the inner workings, I started thinking that some of the adopted solutions could be further refined. They had several noticeable "stop development points" of life. So I decided to experiment with different new approaches, and over the years I have been collecting Cubes, screening the best solutions to problems and putting them together. I now have a very interesting and simple solution for some of the major problems. Basically, it is a more efficient interior design, one that will take advantage of the residual interstitial spaces inside the Cube. I have even applied for a Patent Pending status for the new arrangement and the custom parts.
One of the biggest, if not THE biggest challenge was how to remove the heat generated from the Video Card. It is ironic that the almost out of scale (big) main heat sink was not helping the matter.
The first approach was to install a combined cooling design that transferred the heat through cooper heat pipes to the main heat-sink a modified cooper “Schooner” right on top of the heat sink . This worked, but it was not a practical solution. I used this computer for years. MAMC CUBE (last picture) was the very first Cube to have a 256MB 9800 PRO (full size) in an original enclosure and fan-less GPU with a cooper “Schooner” and heat pipes. At that time I thought that “that was it“ for the Cube expansion. But the next step was not so common at that time: water cooling. And of course, if the “Fan-less 9800 PRO Original Enclosure” was impossible, the “Water Cooled 9800 PRO Original Enclosure” was just a dream.
I started unconsciously to look for radiators with the appropriate size with vertical not horizontal alignment of the fins. Not a chance, ALL the existing computer water systems were still big and had a sideways fan radiator, which made it very difficult.
One day, I remembered that the water cooling system was not for the computer, it was for the video card!
I rediscovered "The Tide Water". It was not only perfect, it was the perfect size, the perfect material, the perfect tubing, the perfect alignment, the perfect shape, perfect universal clip and on top of that it was designed specifically for a video card...
After that I started the CubeGTi project that involved organizing the previeous ideas and putting them together in a unified Kit to have a simple solution for the design problems. The result: a different Compact Computer Arrangement with the capability to hold the Water Cooling system to cool the ATI Radeon 9800 PRO in a G4 Cube with the original enclosure.
