oh sure, right when I'm getting ready to order a WW block you go ahead and make this sweet block hehe :)
You are amazing Cathar.. I'm speechless, your designs are so creative.

please keep us posted if your ready to sell one. thanks
Since I'd had so many requests I've decided today that I will proceed to get a batch made up. Looking at 3-4 weeks. If anyone's interested, drop me an email via my profile, and I'll add you to an email list to send out some information when more arrives.Quote:

d-tek will hate you right now cathar LOL... keep them coming =)
One of the documented "understandings" between DTek and myself was that I would be able to continue research and make and sell blocks myself. I am a low volume hobbyist producer and my blocks carry a significant price-premium, and all I'm after is the ability to fund the research. DTek would barely even notice the presence of the Cascade in terms of market impact.Quote:

That's what I think is so cool about this...you could've sat on this for a few months, let the White Water make lots of money, then release this information, but you do it a scant few days after your flagship block released...
I applaud you, sir :D

I hope you don't mind me ascing, cathar, but do you see a future with d-tek for yourself. It is clearly proven that you are making the best blocks out there and d-tek has the resources to produce them. It would be nice if you/d-tek would continue to provide these blocks to the masses.
As far as market impact some ppl might want to wait for this cascade but I'm sure the marginal amount of blocks you will produce won't make an impact. By the way how do u do it!?!? Do u see the end of waters abilities on the horizon or will u eventually bring the proc to the water temp =) ?
I sent you an email as soon as I saw your post. I would much rather have a block handmade by the master himself than one mass produced by d-tek and am willing to wait for it. My Great Uncle was a Master Craftsman who made violins. I spent my hours in his shop watching him work and gained an appreciation for such things that will stay with me forever. :D Your new design takes watercooling to a level never before reached....basicly rendering all other blocks absolete. Quite an achievement and I will have one handmade by you....that's pretty exciting to me!
ya thats quite an acheivment when u build a block thats better then the best one out there!
I've been happy with DTek so far and don't see a reason not to continue the relationship. I do the hard yards to get the design off the ground, proven and acknowledged, and so long as the White Water production cycle bears fruit, then it's all good.Quote:

I'll hold the Cascade close to my chest for now though and keep making them myself. I've got some rather large bills I need to pay and while I can't match DTek for production capacity, I can move faster to get myself back in the black.
How do I do it? I'm just really interested by the whole thing and put my mind to it. I always knew that better than the White Water could be achieved, but it never clicked to me until about 3 months ago as to how to achieve it.Quote:

I do see an end to how far we can go though, and we're getting very close.
Of the CPU's temperature rise that I see with the Cascade, about 75-80% of it is unavoidable due to the thermal paste layer itself.
Of the remaining bit that is the actual waterblock's responsibility, I'm acutely aware that I'm pushing up a hyperbolic curve in terms of difficulty of achieving better temperatures. For my test-load scenario, I really think that more than 1C better for a structually sound closed-block (non-direct die) is out of the question in a practical sense, and getting that last 1C is something that I can only theorise about how to do, rather than physically build it.
Beyond that last practical 1C, is another theoretical 1.5-2C or so but achieving such is beyond commonly understood theory with regards to water's cooling potential.
So the next rational step is direct die cooling =) problem solved LOL. I saw a few prototypes at procooling. I'm guessing thats where u got the idea for the jet streams as well. Unfortunately I don't think there is an easy and practical way to implement direct die cooling so it would be just for the few pros out there who have the balls to put water on their chip.
I was direct die cooling a year ago....well there was a peltier on the chip and then water directly on the peltier. It would be fun to see what happened if you put water directly on the chip, if you had some old gear that you didn't mind trashing. :D
Cathar... do you think that you will ever make P4 versions of your WBs? JW, thanks!
I have heard that the LRWW is also good for p4 but I would imagine Cathar's block would not be good performers for the p4's wih heat spreders. It looks like cather focuses on cooling a very small surface with his blocks (such as an AMD or p4naked die). Please correct me if I have made the wrong assumptions about the large surface of the p4 and the performance of cathar's block with p4 chips.
I have popped off p4 heatspreaders befor and its quite easy but i never tested the chips. Cathar, have u tested p4 with hs vs bare?
Here's someone who removed the HIs of the p4 and compared it
http://www.overclockers.com/tips1087/
The hottest part of the p4 is right above the core, that's where Cathar block is the more efficient, so you'll see a drop in temp. Cathar made some test himself and notice a good drop
:toast: GREAT BLOCK:toast:
I can tell you that the WW is excellent for the P4... I switched from AMD using the same cooling and same block. As has been said, even on a P4 the hottest point in the CPU is in the center of the Spreader and that is where the WW concentrates it's cooling. Currently have my 2.6C at 3.6 with 1.65V and 41 -42C load on an Abit IC7 which many claim read temps way too high.Quote:

Yes, I get aluminium mounting plates made up on the CNC mill. They clamp over the top of the block. Am getting a prototype one made up for the Cascade that has an oval shaped central area that follows the O-ring curve so you can still see the innards of the block, while offering a light-weight and strong mounting bracket.Quote:

The P4's CPU die is 11.3x11.3mm in size. The heatspreader is 30x30mm in size and is 1.27mm (0.05") thick. Quite the contrary to its name, it's not really a heatspreader if you cool the central section of it well. As long as the central 16x16mm area is cooled very well, the rest of the heatspreader area may carry well less than 5% of the total heat-load.Quote:

In essence, the heat-spreader more or less acts like you have a thicker base-plate on your waterblock. It is an obstacle to cooling for every device that is used to cool the P4. If a device is focusing on cooler the entire IHS area evenly, it's actually cooling it the wrong way.
What annoys me is that some artificial P4 test-beds use a 30x30mm lump of copper to simulate the heat pattern of the P4, and this is horribly wrong. It really should be done as a 11.3x11.3mm die with a 30x30x1.27mm chunk of copper on top. The heat flow patterns are dramatically different.
man I have no words for this design of block.....is drool good enough :slobber:
Okay, got some final pictures. I'll be getting a batch of these made up in about two weeks.
The silver plate is a P4 mounting bracket which fits over the top of the block and is held on with longer clamping screws (just like what was done for the White Water). The final P4 bracket will have a chamfer on the inner oval edge which isn't there on this prototype bracket. This gives a much cleaner look.

keep on drooling :slobber:
nice job cathar....wish I had one in my hands too right now
Have you noticed a diff between the two barbs and three barbs version?
Nice job, it could be nice with a blue led

LoL I was wondering how long it would take before someone said that. :D
That would be like an already beautiful woman who wears so much makeup that she ends up looking like a ho, in my humble opinion.
Why i think it will only make it better (talking about look)Quote:

ps i agree with you about women, i like them without makeup
