Full Cover blocks

[Eddy_EK]

Hi!

I have made a few blocks, and I would like to share some pictures with you.

7800 GT/GTX 256/512

X1800 XT/XL also for X1900 series

Prepared for Crossfire:





X800/X850 series:


Cooling bridge for back-side rams:


I have attatched new NF4 water block and other stuff.

Your comments are welcome!

VERY nice! Do you have one for the X800 line? The "Crossfire" ready one looks like the X1800 series.

Awesome job!

These blocks was first sample, mounted on 7800 GTX 256:

Dude, those blocks are beautiful!!! Two things caught my attention, though...

* The surfaces wich contact the items to be cooled don't look flat enough, there are som visible ridges on them. Have you lapped them after taking the pictures?

* Why not using copper for the back ram and mosfets cooling extensions? Aluminium probably works well enough, but was there a reason for the choice?

The surface is good enought finnished. The ribbs are seen because the angle of light.
Mirror finnish is just for eyes

As always, your blocks' machining and attention to detail are outstanding, Ed!

Now we just need to get them tested head to head with some of the more popular blocks. Needless to say, I am seriously considering an entire set, especially since the additions of LEDs and plating are available.

Now you just need to get someone to translate a few sections of your site, and possible english forum, if you have enough english speaking clients!

I (we) are planning new website www.ekwaterblocks.com.
It will bo totally new designed and totally translated in English.
Don't think of having the forum at the moment, but could be added later.
Now I don't have enought time to translate everytnihg to english.
The tests will be, hopefully soon.

[ProHandyman]

Great to hear about the website redesign, Eddy! Redesign will help as word spreads about your products. Keep the quality... don't go the way that S******* has!

With biz picking up... I'm sure your way more busy then you wish (well sort of), I was self employeed myself till my health decided otherwise).

Does that full-sized block for the 7800 series block work with the 6800 series of video cards? I'm finishing a case mod soon and am using an XFX 6800GS. I OC the 6800GS a little at 525/1200with a DD Maze4GPU, but with better cooling I should get it to be stable at 550/1300.

Good enough is not good enough around here. Do it right or dont bother.
Lapping is not for "eyes", it serves a purpose ie to make better contact with block and therefore better heat transfer.
Nice machining otherwise.

No need to be so "harsh". "Full Mirrior Lapping" serves very little purpose in most applications. Hand lapping can even introduce surface irregularities by rounding edges, etc. I agree with the need to be "at the top of the pyramid", but even such "hair splitting" has gotten into major flame fests here.

Ed's machining is quite good for a "retail" based product. It is not made for the esoteric crowd.

[Bevel]

The base of that block is harsh, not me. If you think lapping serves no purpose you have much to learn.

I DIDN'T say it serves no purpose. However, I did mentioned that improper lapping can diminish performance! Most machine fine finishing (like DD and Switech USED too) is adequate.

I am thinking I will forget more then some will ever know (unfortunately, that's started... and you don't know me or my background). Enough said, since I am not going to get into a petty flame fest that may need more then cascaded phase change cooling to control ( or personal attacks... good way to get banned).

Hmmm, me wonders if being an American has ruffled some kiwi feathers...

Like DD and Alphacool are selling the same water block for 7800/6800 the blosk fits on both.

About the mirror finnishing... it is really just for eyes, although i can admit that my finnish can be improved but for whose sake?

[unreal]

So those x850 blocks still on time for Tuesday?

Might very well be interested!

I dont have a problem with that - just ask bobkoure - unless your name happens to be Bush. I mean how on earth could you elect a monkey, really?

Ed admits his blocks could be better finished, and that was my point - those ridges need to be flattened. Nuff said.

Don't look at me as a backer of the Cheny Mouthpiece! I'm a left-winger!

I'll meet you on the point they could be finished a bit more as what Ed may feel possible/ appropriate!

There, I've done more for world harmony then then the Conservative Cowtells in control!

[Bevel]

Agreed, putting my nukes away LOL

Ed those are nice blocks, just lap those bases and make them real nice.

Now pro your thoughts please. I have had this idea for awhile now, you see the thing is if the Storm block works so well on a bare core why not produce a gpu block using the same principles ie jets? The concept is proven to cool better than pins or channels. Worth investigating?Hmmm

[Eddy_EK]

I see I will need to improve base finnish.
I am just wondering how much will it prove to be better.

I have wondered about that myself... GPU blocks are designed with flow in mind, not ultimate cooling availability.

EK, Aqua-Extreme, and Swiftech seem to be going to slots or grids (not pins yet- though pins reduce turbulence when used in a "cross-flow" design... thus the slot grids and "waves"). The answer I believe is that 2 very restrictive blocks in one circuit will reduce flow so much they would offset the increased performance. The other is design limitations, ie: the amount of space needed to get water in and too "jets" without being extremely restrictive. These type GPU blocks would never work in current space limited SLI/Crossfire configurations.

Testing and evaluating GPU blocks and CPU blocks will raise the "can of worms" that has practically tore this forum to pieces. I see both sides point of views (how UNLIBERAL like)... but, I tend to "lean" more to BA's position (if only I'm "mature and grumpy" myself). "real world" testing has merits... but hardware abuse, calibration abilities, and "repeatability" do factor in IMHO. (Here comes the flames... would rather save them for my case paint, and heating home... getting damn cold again!)

Ed, being the one in your corner, I believe that getting to a fine machine finish that is just short of "mirror" is more then adequate! (I myself would strive for the micron surface ripple that a well machined racing cylinder head surface would have). This would have to be with limited to no obvious visual "fly cut" markings.

Full polished-mirror finish is an extreme operative and esoteric visual for reviewers and "those easily impressed by bling". If the occasional client wants the "ultimate finish", make it available at an added cost, due to extra "time and effort" used. I being an entrupeneur myself, totally understand the level of desired finish to what's fiscally reasonable. This level of manufacture could be offered as a limited or special edition, possibly offered with other "bling", such as your plating and LED lighting effects, or even a "signiture edition".

Nice thoughts

[ricecrispi]

Set some diamonds in the special editions TOO.

Flatness is important. not bling
If he has a flat base I could careless about a few polishing marks.

[Bevel]

Ed - You will see a decrease in gpu temp with a better finished base, good contact is important.

Pro - If the inlet and outlet of a jet gpu are bent 90 degrees I think there will be enough room even with sli. It is possible to put another pump before the gpu's to supply enough pressure. As gpu's become more powerful they would really benefit from better cooling. I think this idea has merit.
