This has given me a great idea..
I'll be starting WC when I have enough money in a few weeks, so I was thinking of converting my (air) MC 462 to watercool just like this one does. I'll see what happens. |

Lets talk DIY - Presumably, an individual with a small drill bit (3/32"? 1/16"?) some patience, and a drill press could create a reasonable imitation of this sort of pin density and size using the #rotor method, then fabricate the halfmoon and slap a top on. I realize the pins would be diamond-shaped rather than round, but I still think we'd be looking at a new non-CNC DIY performance king. Any thoughts?
EDIT: Added concept drawing

not upset, a reviewer can do as they wish (cut your hand, eh ?)
not interested in adding fuel to the fire, but Jabo is closest - but incomplete |

I think I'd just buy a MCW6000-A rather than drilling all those tiny holes...
Almost all heatsink bases will be too thick for optimal performance. |

EDIT: Re pH's comment I agree - thats 361 holes (19x19) with a very small drill bit - not a quick task. Then add in the dremeling - seriously fiddly work to make sure you leave that halfmoon unbroken. However, if someone has more time than money, or simply would rather make the block themself, its not a bad idea. I'll most likely be getting MCW6002s for my Opteron system, but I'd still be interested to see the performance of a DIY MCW6kClone.

Well they took it to the gates in performance, now if they could just do a little bit about style. If I get it I think I am going to have to cut a custom retention piece to give it a nice looks because right now that just says "Sweater Vest"

I suppose one could chrome or nickel plate the wb top (you can do this w/o dipping the bp right?) or powder coat it.

we have some colors 'in the mill', no timing (weeks away)
do not powder coat the wb, temps too high |

Les-> why do you assume that calling Poiseuille's Law equals thinking laminar flow? Re number increases with coolants velocity, right? Pins/crescent by producing an obstacle create localized regions of high velocity (think about high rise buildings and windy day) increasing Re number and thinning down boundary layer. Geometry of Swiffy's block enhances 'verge velocity' of coolant. Please, do not make me to go into more detail, I'd bore myself to death doing so Flow control=equalization of coolants velocity=>more coolants particles participate in thermal exchange = much better efficiency and performance allowing this block to come close to jet type designs. Teaser-> what about a design having impingement velocity flow at every point of water-copper contact over the whole footprint of a block's base? Wouldn't that be just fantastic? Impingement designs base on velocity since it was devised to achieve max cooling density per mm^2. Now, without using nuclear reactor size coolant pumps how would you do it in PC water block design using DIY methods (dead cheap solution in watts/£ ratio)? P.S. That's why I asked you BillA about your R&D, costs and why such design and not 'something new' |

We all know that turbulent flow in heat ecxchangers is what we are after. I never attempted to give Poiseuille's Law as an universal fluid flaw description tool. It is useful with arriving at turbulent flow. After critical Re value is reached we are in deep $hit as far as mathematical description of such flow conditions is concerned. There are two ways of approaching this (well three if you account for expriments). One is probabilistic apporach where you use massive number crunchin power to predict where groups of/single particles are at the moment, their velocity vector and calue. The second one is simply calculating movements of each and every particle of coolant - number crunching power neded is mind gobbling here but calcs are extremely simple. I just wonder if it would be possible to limit number of calcs by entertaining nono-scale model where number of molecules is extremely limited |

It looks very dirty in there from the the brazing... and this has not affected the performance! I thought the scaling would hinder the cooling properties of copper. |

Now I really want to see how a Cascade performs in reverse. A slight suspicion has been growing for a while and the performance of MCW6000-A makes me wonder.
The question being is the key true impingement or purely turbulence. (not suggesting it should be the same backwards as forwards, merely considering the mechanism) |

Thanks for the clarification. Cascade is more restrictive in reverse though, but it could be done. I'm busy testing now so I'll throw the SS on in reverse and let you know how it goes.
The Cascade kinda muddles between "true impingement" and turbulent flow hitting structures. A "true impingement" is something that is much more widely spaced out, which I have built and played with, but the effect of the cooling is somewhat uneven, and while offering overall temperatures about the same as a White Water, it doesn't allow for as stable CPU overclocks. To "smooth out" the heat-flux requires adding more bp material, but that then costs with increased temperatures and lowers the benefits seen when boosting the pumping pressure. I have often described the Cascade as more of a turbulent mashing of water in each cup, even though I refer to it as a real impingement block, it strictly isn't - however it is more of one than most anything else on the market. The MCW462-U is perhaps the only block out there that could be classified as "true impingement". So yeah, you're right, a turbulence mashing is perhaps a better description and can be achieved in many ways, be it a mash in a cup, or a mash around some pins, or a mash following some (optionally bumpy) fins. |
