Cascade water-block design

[Cathar]

Oh I can't wait. I just hope you got my email. Earthlink servers have been crapping out on me, but I don't want to bug you!

I've been a little slow in responding to emails. I've probably got it. Been rather busy setting up the website with my limited skills and making up blocks and attending to a group of people who rolled by my house to grab some.

Hey Cathar, if rolling by your house is what it's gonna take, I'm buying an airplane ticket!!

Just don't forget those of us across the ocean, man: hide a few of those blocks in case more people stop by

you know i do have 1 very big issue....

i havent had a good nights sleep in over a wek because i been dreaming about this damn block and designing the ultimate uber looking WC setup computer

im not joking . its taking me 2-3 hours to fall asleep because i will lay down and try my damndest not to think about it and the next thing you know im up again cause i cant sleep so im on the net .

Dude, it's just a waterblock.

Just as a reminder though

And I thought I had issues...

Hey! Nice job on the site Cathar!

hehe its not just a water block for me.
you see i dont have any friends where i live here in japan really cause im married and have kids which means i dont have a lot of oprotunity to go do things other than with my wife which is nice but since all i do is work a 9-5 5days a week job and come home i need some kind of hobbie to keep me ocupied and currently the only other 2 things i do is lift weights and play online games but being as i have such bad hours for games i havent b\even been playing them much lately . so i focus on a hobby .
only problem is ipicked a really expencive one lol.
not to mention after years of running around the world with a weapon and an alice pack ( yes im a reired 18D ) my sleep habits are all screwed up and its taken me the past 4 years to even consider sleeping at a semi normal time .
hehe guess i do have some problems

so anyways ...... i wanna see my silver water block

and oh i love asian women so much i moved to japan =)

a quick question. hows the hydra gpu blocks coming? and will you also have a NB block too? i would love to have all 3 in a series with a 1250 or 1260 pump

 

[bdunosk]

Any plans to export the design to Dtek like the WW?

So for the Latin American people, hope mine in 2006

The cup idea, to my knowledge, is actually a fairly new thing. I haven't been able to find any information on it either.

It works better than a non-cup implementation though for our needs.

Cup idea is not a new idea, some studies by Ekkad and Al. for exemple show that convective coefficient is higher using cups because there aren't any collisions and cross-flow between jets that create secondary stagnation zones in some cases. Geometrical ratios are specific to a certain impingement, it's not the same like on plate without cup (flow with cup is disrupted by a contrary flow).

All is already done about impingement in PhD thesis or technical studies (single jet or jet array) but on Google there is only a small part of them, you should go in a library with technical books about impingement, thesis papers about them like in some universities, all is written

Equilibrium between base thickness and impingement is not easy, the thermal resistance (Fourier+Rs and convective resistance) are bound and the thinnest base is not necessarily the best in comparison of the size of the jet grid and jet velocity, you decrease a very small resistance from the base but increase convective Rth...

watch out Cathar, I just saw a block just like the white water for sale on eBay!

Yep, fairly close.

Primarily associated with air-flow and the corresponding design for an air-flow cooling scenario.

So impingement cups have been around for it. Never found it on-line before. The final adaptation (being everything that makes up the final design) for computer component cooling that exists in the Cascade design still appears to unique.

Thanks for the links.

I can't wait for my e-mail letting me know I'm next on the list. This will be my first waterblock, so I figured I might as well buy the best. Thanks for all the info you've provided on this thread Cathar. Great Work!
