Waterblock design has begun to focus on the point of entry of the water - In particular, it should be centered directly over the cpu. Your design is typically called a cross-flow or maze - Simple and effective.
A little company in Australia pioneered a new design years ago, using impingement. You can read-up on it if you do a search for White Water or Little River Waterblocks.
dangerden.com now manufactures a waterblock based on the original principles from Little River. I modified your picture below to *roughly* represent how this style waterblock is different.
In a nutshell: Inlet is in the center, so the coldest water hits the hottest part of the block and also minimizes the diminishing effects of surface tension via the velocity of the water hitting the base from a vertical entry, as opposed to traversing across the center of the waterblock with a lateral (maze) type flow.
The fins in the center should be smaller, as to maximize surface area above the cpu. Outerfins should be designed to primarly direct the flow to the outlet ports-
On a sidenote, you can use one outlet port, but then you're design will be asymetrical and as such, suffers a minor performance loss when compared to a dual outlet design.
The picture below is anything but a template. Its just an illustration of a few design ideas.
On a final note, one of the most important aspects of the latest waterblocks, is putting some sort of resistance in the entry port to accelerate the water. A nozzle with a slit cut in it is a popular choice. The stronger your waterpump is, the more resistrictive you want that entry point to be, which results in higher velocity water hitting the bottem of your block.
