Given water flow-rates above about 2LPM (0.5LPM), the thermal capacity of water ceases to be an issue of any real concern in the performance of a waterblock.
What I would have liked to have seen was whether or not a top-end "German" waterblock at 0.25GPM can indeed outperform, or at the very least equally match, a top-end "US" waterblock that's running at 1.5GPM.
If it can, then that's pretty much a conclusive decider in saying that US setups are inefficient and all the other blather that goes along with that side of the debate.
If that's provable, then that pretty much means that we can all switch to 6mm ID tubing, throw away our powerful pump, and stick an all-brass C-systems pump with push-fittings (or an Eheim 1046 for the Germans), and forget about the current line of development being followed in USA/Australia.
That, to me, would be more of a revolutionary ground-breaking shake-up and wake-up call to all the USA and Aussie block makers.
I want someone to prove to me that the USA/Aussie developmental approach has gotten it all wrong.
The closest thing I've yet seen is the Hydrocool Hydro-Stream HS-5 block (designed by a German engineer living here in Australia - but truly a "German" style block). For JoeC/Overclockers, at 0.3GPM the HS5 has a C/W of 0.139. For the Asetek Antarctica (White Water clone), it has a C/W of 0.118 at 1.5GPM. That's still a pretty handy lead for the "USA". Heck, extrapolating a bit of math with respect to pressure drop and holding pressure drop constant across both blocks, and the copper Asetek Antarctica holds a 0.015C/W lead over the Silver HS5.
I want a German block to show me the error of my ways. I want to not use a strong pump to achieve the best possible performance.
The Cascade is a 17-month-old about-to-be-totally-obsoleted design. How long has the Alphacool XP been out for?

i know watercooling is not just a waterblock
but i just want to know having a thick base, does it affect the performance
with the same design, waterblock with thick base and waterblock with thin base, which is better, thanks
