Hi bros and sis ( If any:rolleyes:). At last i make it happened. My new rig is up and running again with out a volcano inside::).
For a long time i was suffering with the issue, How to make 3 slot VGA cards( In my case Asus GTX 680 D2T 3 slot cards ) run native in MVE With a mounted sound card.

First problem i got is when i try to mount 2 cards in MVE PCIE 1 slot and PCIE 2B slot(2 native slots) you cant mount any sound card to any other PCIE X8 or X16 slots. if we mount a card to any other slot (except PCIE X4) slot PCIE 2B will be disable. The thing is if i mount cards to PCIE "1" and "2B" i cant mount my sound card to PCIE X4 because 3 slot card block the X4 port.
The second problem i got when we run a 3 slot card in sli the first card get over heat. This let me no choice but go water cool.

This is my first real custom water cooling rig build by my self. The box I made by my self:cool:. Tubes may be too long but cant help. I think 2 Pumps can handle it. After water cooling, Temperatures drop from 45 to 26 in top card and 33 to 28 in second card:). It was a hard day yesterday but after all it looks cool. At first i was having tons of questions. I was lucky to be a part of ROG family. I got all the answers and guiding in very quick time. Save me of making mistakes. Special thanks to Zka17 and KKn for The help :). For all others who help me "thanks":).
