very cool project!

Could you explain in a little further detail how you rigged up the rads to use those 1/2" fittings?

I had an idea of turning some aluminum down on a lathe to match the i.d. of standard automotive radiator hose, then drill/tap the center for an EK or simliar fitting to mate up to it. Then just use the automotive hose to go from the radiator to the turned piece. I could do it at work, and the only thing it would cost me is the cost of the tap(don't have the correct tap size at work).


Also, is there any give on the pumps you used? Maybe a sligthly more expensive, although quieter, pump you could use for this type of application? I typically water cool for sound levels, and it always has been a lovely idea to me to use an automotive rad. Just never thought I could get a quiet pump to fit the bill.

I took a break from watercooling when I got these GTX260s, but I am gathering parts now to move back into liquid cooling. It would be very cool if I could go a route similar to yourself for my next setup.
