oh shit, feel sorry for you
maybe you did a mistake. you need M2.5 screws. in the first revision AC didn't send them with the aquagrafx6800.
if you don't have them you can use the original screws of your video card, or mail to support and let them send you the m2.5 screws or you buy them.
that could be the reason why the aquagrafx didn't cool properly and the gpu died.
if i said sth wrong here pls correct me guys
