Im actually still using all the Corsair pumps, the H100i for the cpu, and the H70 and H50 for the HD6970's. Im adding red tubing and setting up them in a parallel. I don't have all the details worked out yet but I am going to use a flow meter to test the pumps independently in different setups to see how good they do. Also I have a great aftermarket pump that was designed for RV water systems but it has a good GPH rate and great PSI and head pressure, Its also self priming and can be ran dry with no damage. The real issue is figuring out how im going to set it all up, I may have the powerful pump on the three big RADs. I am open for any opinions. I should get the rest of the parts within two weeks or so(im stationed in South Korea). I wanted to do sum thing different and the project out grew the Zalman case I had so I ordered a Corsair 800D. I have been talking to Corsair threw letters trying to get Sponsored and get some free stuff and so far it sound good! I got the Corsair cables for extera and I intend to wrap the Cougar psu cabels in PET. I dont have a Corsair PSU yet because im on a budget and I already invested alot of money in the 1000w Cougar PSU, but I do intend on replacing it with a 1200w Corsair (hopefully for free!). Overall though im happy as long as I have a all red and black build at the end..... I have a 16gb Red Vengance RAM kit(1866) but I also scored a great deal on 4gb(2000mhz) kit of those two black ones you see for like $10!, but will eventually get the the other half of the 32gb kit which I will probably still order the black ones bc they go along good with the rest.
