I started to work on this last summer and its my first water cooled system , I had everything ready for 4-5 months now but never got to actually transferring the hardware into it until last weekend , I still have to work on the cabling and fix a tiny little leak on the middle plug on my res (hence the container under) but overall Im really happy with how it turned out. my temps dropped a lot more than I ever expected , my 3.0c@3.45 used to run between 50 and 60 degrees Celsius with a stock Intel hsf . now its down to between 22 and 27 depending on load, I can't wait to get some more time to mess with my overclock , Im hoping to be able to hit 4ghz with this , I had it at 3800 for a long time but then my hsf got clogged with dust and I didn't have any compressed air so I had to back it off a few weeks ago. as far as my 6800ultra goes it ran at 75-80ish before and is now down to between 49 and 57. I never overclocked it before because I wanted to keep my warranty intact until I actually installed the water block on it and void it. Now that its gone Ill crank it up this week and see what this thing can really do.
