yeah i dont get it... it says on the website that its suppose to be enhanced for water cooling... but i dont see anything speciall about it... the blitz on the other hand has a NB/SB/and mosfet WC blocks integrated in them, thats water cooling. (although idk if its a good idea cause it would put alot of extra heat loop, if you already have a quad and a 8800gtx on the same loop) idk if that would be worth it. and to bad its only DDR3
