Water block for this card

[thefinnnwi]

I purchased two Sapphire 6970 cards, http://www.newegg.com/Product/Product.aspx?Item=N82E16814102915 , and I'm having issues finding out if it is a reference card or not. I intend on water blocking them, but can't do so until I find out. Any assistance would be appreciated. Thank you.
