The "turbulator" will be a crosshatch pattern dont via a dremel in the bottom of the channel.

MeltMan Says: "Hell-o Copper!"

The top bar is 1/4"
The bottom bar is 1/2"

The barb pictured is 3/8" with 1/4" threads, If you can see that small

YES, the bottom bar weighs a ton. It is the mother of all my next waterblocks. Muahahahaha, Stay tuned

Hey, do you have any extra of this copper busbar?

Here is a reply for the thickness debate. You want a decent mass of copper to absorb any sudden temp fluctuations from the core (going from idle to full load, or just turning the thing on, for instance). It serves as a heat battery while it is being transferred to the fluid ... it serves to cause the dT of the block/core to be more of a smooth line during changes than a sharp spike. That would be another advantage of a bottom plate extending to the corners (besides stability): it is one more place for heat to hang out while it waits to get xferred to the fluid. Since this block will have a very small copper mass compared to, say, a maze or jagged edge block, a thicker bottom would be helpful. The thicker it is (to a point!!!), the smoother dT you will have on the block and cpu. You'd do best with around 1/4" (5.5mm?), methinks (you have the same issues with a peltier unit when you use a superthin cold-plate ... lower heat spreading from the cpu to the pelt as a whole).

Oh, if you want some shweet copper for modding, go here: www.onlinemetals.com. You can get any amount in damn near any size and shape of copper you want. Go nutz.

Yep, but that copper costs money, this bar was free.

I did re-do the design to be square based, but heres the problem, the width of the block will only be 1 inch! 1/4 sides plus 1/2 center, so I'll do some creative brazing to make it reach the athlon feet.

Go to your local scrap metal dealer. I buy copper for $.50/lb. Did all my waterblocks and chillers for under $25.

I'd be afraid of buying metals from a local scrap dealer unless they can certify metal content. The thing I like about online metals is that they certify the content of their metals. I've met some real fly-by-night scrap dealers, and I wouldn't trust anything they would sell me. But then, I'm in the BFE, also. Maybe it's different where you all live.

I wouldn't pay ANYTHING to have my neighbor's Volvo melted down whole and turned into a water block ... well, maybe a little ...
