Water cooling pny gtx 680

[blazrg]

I have 2 pny gtx 680s i want to water cool but i cant find any solid info on a waterblock. There is a couple of videos on an ek block but their site says this model isnt compatible. I know reference and aftermarkets are different but how would i kno pny would work with other brands. Evga or another reference brand?

Realistically there is no worth in water cooling those cards.
Not only are you going to struggle to find compatible hardware, but the money invested would easily buy a single, better card.
