EVGA GTX780 FTW ACX Waterblock

So i've read through many forums and i see many say that the 780 waterblock doesn't fit BUT some say that a specific Titan(i hear that there are 2 different Titan builds) waterblock fits.  I can't get anything clear on which Titan block because many manufacturers build a universal Titan/780/780ti waterblocks.  Pretty much they said the original had a different design and then later was replaced with the current design.

 I didn't even know that the Titan had a revision, i thought they were all exactly the same. I'm wondering if anyone knows anything more about it, i'd prefer getting a full waterblock instead of a GPU only block.

You have a card with a custom pcb, therefore unless a waterblock maker like EK design one for that exact card then universal blocks are your only option.

I have the same card.  This one will work fine: http://www.xs-pc.com/waterblocks-gpu/razor-gtx-titan-780-780ti
