I'm posting this on behalf of an acquaintance, any suggestions very welcome. Thanks.

Well Ive been thinking about a WB idea for a while, and I finaly got board and designed one quick and dirty.
http://www.modders.net/uploads/Rastlin/xstorm2.bmp

Thats a quick drawing of what I think would work, the concept is simple, 2 Angled inlets enter, one at the end of each bar with densly packed fins. The incoming water from each channel meets head on in the center of the block causing massively turbulent flow directly over the core of the CPU, and removing heat from the tall pins in the center of the block. Then the turbulent water flow follows the area of lowest pressure, and exits over the channels with the less densly packed fins, leaving the block though dual outlets.

Concepts are.

Direcly opposed streams to induce turbulance in the center of the block.

Angled inlets to improve turbulent flow over inlet fins.

Dual 3/8" inlets and outlets, that are Y connected to 1/2" hose, theory is that this will increase water velocity inside the block, without restricting overall flow severly.

Medium thickness base, A thin base should transfer heat over a smaller spot, causing a higher temp in a smaller area, a thicker base should spread the heat over a larger area, but this leads to a lower temp differential between the cooling surface and the liquid flowing though the block. A medium base thickness should spread the heat well enough to make active cooling happen both in the center of the block, and in the microchannel fins.

Tall Pinfins cut from the base via a cross sawing technique, Widely spaced pin's allow for less restrictive water flow. sharp edges induce turbulance. Tall height increases surface area and thus heat transfer.

So what do you all think of my quick dirty, havnt designed anything in a VERY long time, proof of concept design?

Anyone have the tooling set up to build a prototype block?

Also it was my intention to have a 5mm thick lexan top, and use direct bolting to Socket A or P4 boards (different top for each board)
