Flow rates of 0.75-1LPM eh?

Doesn't that then get into the intent of a design? The impingement designs totally rely on adequate pumping pressure to get their cooling performance.

A large number (almost all?) of the "USA" designs, mine included, are totally inadequate to cope with those sorts of flow rates. Crap, I don't even test at anything below about 2LPM, and even then such a result is just a curiosity for me as that sort of flow rate is already well outside of my targetted flow rate range, upcoming designs included. That the blocks that I make with ~1mm bases perform anywhere near as well as they do at such levels is perhaps somewhat of a total surprise to me.

Getting back to a car analogy, this is perhaps somewhat equivalent to running said Ferrari on diesoleum.

This becomes more of an issue of the focus of the testbed. A good testbed will test blocks across a range of flow rates, especially including those for which the blocks were designed to operate at.

I am now left with no wonder as to why no one understands what the sorts of performance differences between the US vs German types of blocks are. At 1LPM at 100W though, and I have almost no fear in stating that the USA blocks when run at their intended flow rates will take the lead.
