Swiftech Komodo HD7970 Preview

[gabe]

Gabe, any plan to support the upcoming Asus 7970 DirectCu II?

Reference designs supported only at this point. But if Asus asks me to make them a Radeon block, I will be happpy to oblige :-)

Today i tried to redesign my loop on paper in order to be ready when swiftech waterblocks arrive. I think i am stuck since i have no idea of the bridges design (input, output, serial, parallel etc)
Gabe, it would be nice to have a preview of those bridges in order to be able to prepare accordingly...

Regarding churchy's post about the bridges, please allow me to add another parameter to the cf bridge "equation"... and that parameter is "efficiency". GPU waterblocks are restrictive, especially in crossfire or even quadfire. So, right angles might be an "effective" idea, but not sure if its going to be efficient as well, since these will cause even higher pressure drop...

Re. FC GPU being restrictive
- when setup in parallel, 2 blocks in SLI/CF are much less restrictive than a single CPU water-block, even less so in triple or quad
- with highly efficient Swiftech blocks, and given the low heat flux of modern GPUs, they are much less sensitive to flow than CPU's, so parallel setup is always preferred.
- I design our blocks with the least possible restriction, for instance, I calculate my channels cross section to be equivalent to that of 1/2" ID tubing or more whenever possible.

I believe that what Martin was referring to in the quoted article is excessive use of elbows.
