Look up reviews on the card, contact EVGA or look up the PCB yourself to determine whether the PCB is reference design. If it is, your in luck as most water-blocks cater to reference design.

You will probably need to spend a bit more than $100 on a GPU block, especially if you want a backplate as well.
