Feser's New Lineup

[Church]

BTW, lately all we see in LC - fine tuning / slow evolution. Imho it's worth to start some new thread with brainstorming of what can be made to radically change some component to enhance it's performance (or radically slash price for same level of performance). Some ideas outside simple ideas like silver instead of copper, even smaller micropins/microchannels, more powerful pumps, more rads and such. I don't like current stagnating state in this hobby and i'm doubtful in these rads breaking the ice of status quo. What can be improved with waterblocks? What with pumps? What with rads? Eg. it was interesting to read one recent thread about non centrifugal pumps (i forgot the term how they were called though), that could do way more pressure then most common LC centrifugal pumps. Or thinking about basics for waterblocks - what are theoretically best in taking heat, and how one can make one more close to that theoretical (eg. thickness of base) without compromising other things (eg. mechanical rigidity), or what else except micropins or microchannels can be used to enhance turbulence or enlarge heat exchange area and still is technologically simple enough to make. How about old idea of TEC + waterblock? Anything but to get out of current swamp of microgains by slowed down evolution.

What I think is funny is that even when the research money is available for advanced concepts for heat rejection for things like advanced fuel cells and space applications, heat pipes, louvered fins, and microchannels are what they use. Of course, there are expensive tweaks which increase efficiency like advanced materials or extensive optimizaation but essentially that is state of the art I think. This is part of the reason why I'm really curious about this launch and especially with the claims above.

That was the meaning of my post too. Cray dont mind one second about costs. They are providing the most powerful computing solutions on earth (along with NEC and IBM), i dont think they would cut corners on anything. The cooling system used for the Jaguar for instance is a very interesting design, but again i see fins and microchannels... I know the army use watercooling on some equipments, they have specialist engineers who develop full board WB's for their rackable computer boards, those look a lot like what EK does.
I have seen that kind of tube rad (from what i guess on limited photos we have for now) but it was for liquid-to-liquid heat exchangers, not liquid-to-air. As air has a very very low density and heat capacity (well, compared to water), the heat transfer coefficient has to be improved by huge surface area, and that where fins come in. I'm curious to see a proper closeup of their tubes, what counts is the total surface area exposed to airflow, and of course the air flow itself.
(edit) and what kind of exchangers are there on the Bugatti Veyron for example ? We know they spared no expense on R&D on that project and selling the cars almost at cost, just for them being technological demonstrators.

if you asked someone 7 years ago if they went watercooling so it would
A. Have bling factor
B. put a 480 rad in their case
C. not use worm clamps

they would think you were craaaaaaazy! watercooling used to be Uggggly, with Heatercores, 80mm fans, worm clams ftw!!! i think in 7 years the technology has gotten there, but the looks omg. the facelift that's gone on for watercooled rigs is AMAZING!! it went from 12ft pole to the hottest dame on the street. so i don't really think of anything happening now as stagnating or w/e but that's just my opinion : ) i rarely make new loops or rigs i wait till they self destruct or i get a new computer.. which has been over 4 years . i personally think the companies are doing quite a good job.. but i don't look at it as a Quarterly Thing.
