Thanks bigben2k.
Actually I had always thought cooling the back of the CPU would be a good thing to try. I mean where else could the heat go but into the water....right.
I had put some thought into this idea some time ago. I thought what if you could extend the CPU pins and then bent out the center to allow for a pipe or tube to get in there.
Here is a rough pic I made just now to illustrate my idea...
That of course is just the basic idea. That does NOT show how to make the extender solid or secure so you could put pressure on it when mounting the water block on the CPU. Also, all of the indifidual pin extensions would have to be kept isolated from each other if they were just bare wires.
Anyways, this my $0.02 on the subject
