No m8 its mounted by the four holes round the socket,so you will need to take of your mo-bo to fit it ,also what im going to do is cut a square hole out of the back of my case right above where the cpu socket is so i can take it of if needed+plus this will save time.
Does this Help M8 + other Neptune Q's over at http://www.coolhardware.co.uk/modules.php?name=Forums&file=viewtopic&t=216 Mat
