I have a danger den MC-TDX water block just about the whole block will fit inside the cpu clamp bracket. It did have a mark where it was hitting the side where the metal bar is that you use to clamp the cpu in it would for sure hit the part where your TRUE rests. I dont have to worry about that with this block. I did cut a little bit of a channel in the water block to make sure it doesnt hit. But still the same problem. The water block shows good contact with the cores when i take it off. but something is happening when i tighten it all the way down. I`ll figure it out sooner or later. Not to worried about it I have my Q6600 in here now running at 3.8 doesnt get over 68 under full load. It is a bit harder for me since i have water cooling on everything so i cant take the board out of the case to see what the deal is. I might get a new radiator next week if i do that, I want to redo my loop make a change or two So the system will get drained and i can pull the board and figure out what the problem is, Plus by then my fingers will have healed and my arm wont be so sore. So i`ll be in a better mood to deal with it. Just needs a tweek or two to work it out
