What about combining this project with your
Pumpblock Project? I think high flowrates above the die would bring a great performance improvement.
But it might be quite hard to fix such an constructions on the little P4...
I wonder if this would work better than a good Watercooler when usig a T-Bred. the P4 die looks much bigger than an T-Bred. When both use the same energy you have to carry away much more heat/mm². Would also be interestig if the direct cooling is still better when using really extreme CPU Voltages. Might be possible that an ordinary Watercooler is better in that case.
