i know the asus direct cu 2 770 has a unique pcb but ekwb has ended the life on their water blocks and to me some of the 970 pcm look similar to those of the 770. My question is all the asus 970's use the strix 980 waterblock and if they look similar, some even have similar screw layouts will one of these waterblocks fit the asus gtx 770 dcu2?
