I am going to try the card with waterblcok only tomorrow and see if that helps. I think it may be shorting somewhere. We will see.
How tight are you tightening the sinks? If you crank the screws down harder than snug, you will warp the board, and you will damage it, and very likely could create a short as the tolerances are tight.

The sinks fit perfectly on evga reference cards, but you should always inspect your individual board for compatibility before mounting the sinks.
