Could you please clarify 0.05 screen and 0.045 balls? You don't mean 0.5mm screen and 0.45 balls? If what you said originally is correct I can seem to find the supplies on eBay. Congrats on the water cooling!!! Kinda thinking, I didn't go this way but on eBay they have water blocks for like 10-15$ Hook um all up with a pump and a big enough rad and that's pretty tits. Just an idea as I know those self contained units arn't cheap on their own.  Check out the water cooling they did with the 60 Ghs models.

FYI I have 8 12v rails 25A, 2 jalapenos a piece. My custom 16 gauge wires are a little warm on the 2 jalapenos 1x6 chips 1x4 chips. The 18 gauge wires from the power supply are actually warm-hot to the touch. The insulation isn't melting yet but I think I need to pull the weak link out.  6 chips still running magical under 60c on air..........
