I have been working on a Mineral oil submerge mining rig for the past couple weeks. I got it up and running so I thought I'd share.
http://youtu.be/EpNERMxvPTkI'm going to fill it up enough to allow the mineral oil to flow over the cards. I also plan on adding a reservoir that the main pump sits in. Allowing the warm fluid from the top to spill over.
Oh, that is really really nice, what is the vram temperature on your graphic card?
