What would be interesting to see tested would be minimalistic water cooling system being used to pump the heat with the same testbed. Once I get my bed done, maybe I'll do it, unless someone else does it before me..
In forced cooling it's usually better to use radiator as water to air heat exhanger, but in case of passive cooling there is no real difference here, except that with water it's easier to pass the heat to higher surface area. But it would be interesting to see the thermal loss while using water when all the other components are same/similar.
In fact, I guess you could even use the mCubed heat-plates if you picked narrow enough copper tubing and passed water through it. It'd make the loop a lot more restrictive, but with pump with high head pressure and this small loop it shouldn't be an issue.
Naturally if the heatpipes do the job, in so small case as that Hiper, they most likely make sense. But just out of curiosity and for larger enclosures it would be nice to have some comparisons.
I also see no reason why you couldn't combine those two.. I in fact plan to do so for the components producing less heat, ie. use heatpipes to gather the heat to a single waterblock and then run water through it. This should provide sufficient cooling for regulators, main memory, southbridge etc.
It'd also be very interesting to build water-cooled system to that Hiper case.. That'd certainly be an excersice in miniaturization
. But given the flexibility of water cooling, it'd certainly be possible.. even some good silent pumps measure like 80x80x31mm (DDC with acrylic top
), which is less than most 1U heatsink+fans, and something like 1/3 of all the waterblock would nicely with within 40mm height, lowest needing mere 11mm of clearance (Koolance GPU-180-H06
