When I first started gathering parts for my watercooler, I wanted to make a maze waterblock, but the beehive seemed to be better considering my skills, tools, and access to materials. The design came from Curly Joe at:

After I looked at his article today, I noticed that I may have placed the inlet in the wrong place. He has his in the center of the pin array, but mine is off to one side. Hmmm, center seems like a good idea. I've got one more piece of copper base, so it looks like a trip to Home Depot for the parts to make another one. Version 2.0! $5.00 should buy two hose barbs, a pipe cap, and some copper wire.

The thing is that with long pins like in the one he made. The heat will make it MAYBE 1/4" up the pin.

Would short pins be better? Is the extra length over 1/4" hurting performance?

Also it's a bitch to machine  And drilling and press fitting is to time consuming for the .2C difference

It wasn't too hard to make. A #41 drill in a drill press to bore the holes. They ended up .002" less than the diameter of the #10 copper wire pins. Hand drill to make the holes in the pipe cap. The pins were a pain to cut with a dremel tool. I went through six of the little cutoff wheels and that copper gets hot! I hammered the pins in with a plastic-faced hammer. It's all held together with lead-free solder.
It did take a day to make, but it was a day well spent with power tools.
