Who ever is considering this block, say stop to yourself.
The original thread (in German) is located
here.
The good thing about the block: it shows excellent milling quality of whatever machine was used.
Now, there are several VERY bad things about this block:
One thing can be said for sure: if this block is made out of aluminium and copper (unless the silver part would be silver (which I doubt) or nickel plated copper (why have just parts nickel plated?)), there will definitely be galvanic corrosion. There is no stopping it (yes, additives can put it off, but it is only a question of time). The block will definitely corrode around the area where there is a transition between the ALU and copper, causing a leak = water on your G80 GPU. I'm sure no one wants that.
Next, there are several things we can deduct upon looking at the design.
The block will definitely be a flow killer. Thin channels, and several U turns. Another thing that is interesting is the orientation of the fins above the core - by the looks, the water just flows above (i.e. there is no direct link). A more logical approach would have been to have the fins rotated 90 degrees - much less restriction and better performance.
The channels should be made wider, with less U turns.
Lastly, the rubber o-ring is just way too complicated. Why not make the block a little bigger, and have an o-ring with straight edges?
Overall, I'm not impressed.
