Thats a great clamp, but its meant for holding heatsinks on. You are holding a peltier, cold plate, and waterblock on there now...and you have to hold them with suck force that they cannot move. I dont htink the current heatsink stuff has the capacity to hold this stuff on. I broke the plastic clip on my socket just installing my clip...thats ridiculous. Im not gonna trust that when im running a p3 800 at 1200 (if i can get it that high) with a flimsy clip. I want something that will hold so well that the processor card will break before it comes off. That said, here are some nasty drawings of what I did:
Hope that helps.
