v Close Look @ VR Zones Dry Ice & Water Cooled 7950GX2 Quad SLI System

I’ve had quite a few people asking me to see more of the Inno3D Dry Ice Automater and 7950GX2 Quad SLI water-cooling system we displayed at Innovision booth during Computex 2006. Here are the details of it!

We were very lucky to have received 2 x 7950GX2 from Inno3D a bit early!

As performance seekers and overclocking enthusiasts, we were not satisfied to have just the cards at default cooling! So I went on to design some waterblocks for the 7950GX2 G71 cores. My dear friend Vinnzz from our VRForums is a professional engineer with machining facilities so I enrolled his help for this whole project.

He came back to me with these:

I simply love his nice skills with the mill. As you can see, the water-block base is to be capped with the copper plates with mounting holes integrated into them. As the space between the 2 PCBs on one 9750GX2 is very limited, confined to one PCI slot space, I made a thin waterblock to fit. Flow rate design was very simple "U" in-out design so that I have decent flow rate. I don’t think a GPU core would require much elaborate water-block design in any case.

As seen above, waterblock with the cover plate only takes up 12mm!

Well you can see above I also custom made 2 manifolds to split the flow of water from 1 x 1/2" tube to 4 x 1/4" tubes. One inlet mainfold to split the water to the 4 waterblock and another to receive the return flow from the 4 blocks.
