that is one sexy block, nice mill work
Wow...restrictive enough? Oh well, a step in the right direction I suppose.
Quite lame...only need a cheap one for the core...don't need aluminum blocks on memory unless they're stuck on and even then..would prefer copper.

Flow will be fully laminar. It`s just a fancy expensive toy - nothing really special :(
Yay for corrosion. I'll wait for Eddys solution.
OMG...nice millwork...restriction city! It is a nice full cover block, but seems WAY to restrictive, all I want is a Maze4. If you don't have a full cover block do you think we will have to cool that front mystery chip? I don't see myself buying 2 Maze's for 1 card. I guess actually this is what we will probably get, the new improved Maze5, after DD tweaks it to fit on a G80. After seeing the shots of the card naked someone should try a CPU block.

That is a good looking part . If I used I would Anodize it inside and out . Black would be cool
Big and Useless
the stock cooler cools the main core, the secondary core, the memory and the vrms, so if a normal maze 4 etc. waterblock is used, cooling for the other component has to be considered. Whilst ramsinks easily solve the memory cooling, the vrm's and the secondary core may need some more creative thinking.
For pure ease of use I could see the all in one 'full' blocks being popular for the 8800, although theres no excuse to go aluminium.
Word. Flow killer.Quote:

Something tells me that I/O chip ain`t that hot. Simple chipset radiator should cool it just fine - with good airflow of course. The only concerne is mounting system. I guess we will see few air coolers with bundle of ramsinks for this card pretty soon.

Yup they will, a couple of wide, sweeping turns would have been better IMHO. I'm still confused as to how water is supposed to flow through the copper section.
Looks OK, but think it'll perform horse poo.
Not through, but over in a thin layor.Quote:

I am begining to wonder, if anyone even has a standard for what "restrictive" means... other then "instant reply to all new waterblocks"
Most full blocks seem like a waste.
It'd make more sense if they turned the copper section by 90 degrees.Quote:

Yeah, watercooling people loved the MCW60...:D

1. aluminum + copper = galvanic corrosion
2. aluminum and copper seal. the galvanic corrosion will happen fastest here, causing a leak right on the core of the gpu. suffice to say they will have some very unhappy customers if they dont supply some hardcore corrosion inhibitors with the block.
3. the gpu core cooling area. whatever moron designed this should be shot in the face. first off lets point out the fact that the fins are turned in the WRONG direction in the picture. now lets assume they will be turned the right way when you use the block. if you look closely at the edge of the copper/aluminum seam you will notice that the aluminum is cut down slightly to the height of the copper fins. this is so that the water can flow past the fins.. and that is exactly what it will do. the slit is at the top of the fins which means the base of the fins will get little in the way of turbulence (which is required for good performance) and thus there will be stagnat water there. this stagnant (relative to the rest of the water) water will heat up causing poor cooling performance. If my explanation didnt make sense lmk and i will do a paint picture
4. the channels in the aluminum. You have got to be kidding me right... nearly every full cover waterblock does this (barring a few). they make these little tiny channels that look like seismograph reading from Los Angeles in order to cool the ram effectively. Get a brain you moron block designers. The ram isnt putting out that much heat and a larger channel with lower velocity water that swept past the general vecinity of each ram chip would be MORE than enough.
5. the complex design of the gasket groove. The design of the gasket groove does nothing but increase the cost of the waterblock. If they brough the groove inside of the mounting screws and didnt have it hug the edges the block would be easier to machine, a shorter gasket could be used and the gasket would be a hell of alot easier to reseat after cleaning the block.
In short, this block was designed by someone who has little understanding of economics or thermodynamics. But hey.. they really know their solidworks :rolleyes:
It's big and it's chunky just like me .. whether it is as useless as me in general though remains to be seen .... benefit of the doubt until someone actually tests it ?

Hmnn.. is the Maze4's base big enough to cover the IHS of the G80? If it is isn't... would it still be able to cool it enough. I recall watercooling the 5900 with an MCW50... and the base of the MCW50 was not nearly the size of the 5900 and it worked fine.
The G80 is a different beast though.
Don't wanna spend 200 dollars on waterblock... especially one such as this.
The maze 4 would work OK I expect, the problem is finding a way to mount it on the card. Then you still have the problem of all the other bits that need cooling. The cost in RAMsinks for the RAM, mystery chip and the power regs might mean theres no price disadvantage to go with a fullcover block, and it'd certainly look neater IMHO.
Not really.
A block will cost you about 40-50 dollars. The upgrade for a new retention bracket is probably like 10 dollars if you already have the block. And the mosfets look like they can be cooled with longer ramsinks... my only concern is whether the GPU will be sufficiently cooled (at least BETTER than stock) with a Maze 4 or MCW60.
Here in the UK 1 of Eddys blocks costs around £55-60, an MCW-60 is £30-35, and then say you need about 24/25 RAM sinks to cover the RAM, power regs and the mystery chip. 8 Swiftech MCW-14s here are £15, so say £10 for some generic ones. Thats a total of about £60-70, so it works out the same. Although admittedly you then hit the pitfall of all fullcover blocks, you cant transfer them to other cards.
That's true. I never did like those Swiftech Ramsinks as they are expensive and they can fall off easily if you are not careful of cleaning the ram properly.
Here is how much they are.
http://www.svc.com/mc14.html
Overly expensive there are lighter and cheaper alternatives that can cool well with a low amount of airflow.
Ramsinks like these can cover multiple mosfets so you don't actually have to tack on an insane amount of ramsinks.
http://www.svc.com/crc-u01.html
And Ramsinks like these can take care of the memory:
http://www.svc.com/sac-p01.html
Then this to cover the mystery chip.
http://www.sidewindercomputers.com/miso.html
All together... it will cost a little more than half of a full size heatsink.
Oh yeh, I'd forgotten about the Southsink actually. I wonder if the CM RAMsinks you linked to are up to the job of power reg cooling, if they are then you have a viable alternative to a fullcover block, at least with US prices!
I'm not sure what you based this assumption on, I can't see it being laminar at all. With the sort of flow rates that water cooling uses and the geometry, it's definetly going to be turbulent. In fact for a 1/2" tube such as that used for water cooling, and for a flow rate of 500l/h (typical D5 lowest flowrate), that gives a reynolds number of ~18000. The transition range for laminar to turbulent occurs from 500-2000 and after that it's considered fully turbulent, and that's just for a simple straight smooth walled tube, so there's no way in the world that the flow through this block is going to be laminer. But in saying that, the mill work is very nice :DQuote:

Theres useful restriction which delivers maximum cooling performance right at the spot where its needed (Cathar's G series of waterblocks), and pointless restriction, with this waterblock is a case in point. As Maxxxracer points out, a wide channel, gently curving around the block will do nicely for keeping the relatively low power RAM chips at a good operating temperature while ensuring minimum possible restriction.
Without any test and already 50+ posted negative...:slobber:
Yup, its gets to the stage were you can just look at a design and write it off. This isnt a new design as such, theres no new cooling method being employed. It's old tech reworked to fit 8800 series. Old car, new wheels if you like. We know the old car's rubbish (long term reliability issues in the case of this block/"car" for sure, performance is unknown but based on past knowledge predicted to be mediocre) and something better with the new wheels will be along shortly I'm sure :D
quite nice block, millwork is quite standard looking for a nc mill. the thing i dont like is that the "water channel" inside the block looks kinda to simple but i gues that the mem chip doesnt need more cooling than that.
Nice piece of work. It looks heavy and inconsistent, many great products looked awful at first, give it time for benchmarks and reviews.
MaxxxRacer is a hater

As I really like the design. It would have been nice if they used copper completely tho. But to cut this product down befor its been tested . I am also wondering if that copper block isn't installed incorrectly. If it were turned 90 degrees it would promote much better flow and dissipate heat much better.
1) complete cooling solution for video card.
2) Flow is relative to pressure.
3) Corrisive- simply anodize inside and out you choose the anodize color .Use a good fluid such as Koolance.
4) Promotes the use of less airflow threw the case= fewer fans. 1 of the main points of watercooling in the first place. :fact:
Relax. There will be better alternatives to this waterblock in the near future. Hope no one is dumb enough to get this.
I am I want to try it . A little anodizing inside and out will take care of the corrission problem . If I cann''t turn the copper water block 90 degrees . i will simply machine channels to make it better at dissipating heat. . Checkerboard design . Since I have a machine shop not a problem . I like the design very much. Anodize black turn copper heat sink 90 degrees. Or machine . Should be a nice little water block.Quote:

LISTEN TO MAXXX, HE KNOWS WHAT HE'S TALKING ABOUT... :fact:
To be honest I hope that this is a test/sample block. As for being restrictive, it's not, look at the area of the channels, you fit a barb in those ports and I bet you the area through the barb will be the same.
The only things I can see wrong with it are....
A, I hate the use of different materials, it looks cheap and lacks a certain quality.
And..
B, it doesn't make the water work.! You need to break the water surface film up... big style, that way it'll dissipate the heat from the block better and more efficiently.!
Just my 2cents worth.
Ya I seen the same problems with heat dissipation. Since air flow and water flow memic each other. Simply dimple the areas were you want to cause tribulance in the water flow.Quote:

That to!Quote:

what other options will there be really?
you will need at least 12 ramsinks for just the ram. plus you have to cool the secondary chip somehow. plus you have to cool the fets.
im thinking this could be a card that needs fullcover solutions for best performance.
but:
make it all copper
widen the channels
change direction of those fins
drill out the middle of the solid areas to reduce weight
make top out of derlin to reduce cost and weight
but i think one thing we can all agree on is that that milled aluminum backplate is freaking piiimp
EDIT: btw, im tired of mods being treated like gods, and some starting to act it. treat them with respect, but get your head out of their asses. ive noticed lately that people are getting some real critisism when they disagree with a mod and their oppinion. and some mods go as far as deleting their post. even though it is in no way breaking forum rules.
with the influx of noobs, and the recent change in some mods behaviour, it seems XS might start to mimic [H]
of course there is still most mods here who are very level headed and are absolutely great.
Ack...after seeing the other picture with the stock cooler off...that's a lot they seriously intend to cool...so pretty much it's either full cover blocks, or a "kit" (pst, hint hint) with the main block, ramsinks, longer ramsinks (4?), and a small heatsink for the extra chip...
You don't need ramsinks. Just place a 120mm fan near the card.

Ramsinks and airflow are already overkill. I'm been running my card for over a year without any sinks on it. The chips are cool when gaming. Just point a 120mm fan at it and that's enough.Quote:

seriously though, airflow is NOT enough for an overclocked card. my 7900GS with ocz bga sinks and 3x80mm fans blowing over it only keeps them moderately cool. and i havent even vddq modded it yet.
same way with my x800pro.
There are a few manufacturers selling 8800's with a danger den waterblock - ocuk have the bfg ones in stock - albeit at a hefty price. The waterblocks look to be copper at least, so may be a better choice.
http://www.overclockers.co.uk/acatalog/8800_Series.html
edit: also avaliable in the states:
http://www.tigerdirect.com/applications/category/category_slc.asp?Recs=10&Nav=|c:1839|&Sort=1
That looks better. Acetal top with copper bottom. Hopefully DD and Eddy will get their blocks released soon.
Not good- Either use all copper, or don't make one. All watercooling setups use copper C110 nowadays. Nice idea, poor design/implementation.
I personally feel DD will release an excellent full block, as they have in the past for graphics cards- Take a hint, use copper :)
SOME CRAZY GERMANS from AwardFabrik.de have shown the world's the first waterblock for the yet-to-be-launched 8800 series.
The prototype comes from the company named SilenX, and it looks menacing. Preliminary testing has relealed that the temperature of the GPU drops sharply by 30 degrees Celsius, from 81-85C down to a 50C range. Overclocking scores also show significant improvement.
Before the waterblock was installed, the GPU was running in high 90s at a 625MHz clock. With the watercooler you can enjoy a 25degC lower temperature and a stable clock of 660MHz for the GPU, which is almost 100 MHz faster than a default clock.
Of course, getting a GPU to run at 660MHz yields in Shader clock of over 1.GHz (a 90nm part with almost 700 million transistors has parts that run at 1.5GHz) and not using AMD or Intel transistor technologies only gives a tribute to engineers at TSMC and Nvidia, who created a small semico miracle.
The reason the cooler works so well is its backside. While the front looks pretty much like many of the waterblocks out there, turning the back reveals the German precision in designing this monster. All of the elements on the PCB are cooled: the G80 GPU, Samsung GDDR3 memory, nV I/O chip and the power regulation.
This enables the G80 PCB to become a warm-to-touch instead of scorching-hot board, especially on the backside. The values we mentioned earlier are for the GPU alone, while the Windows thermal monitoring did not show a sharp decline in the temperature of power regulation, which in the end greatly reduce the stress on the PCB and will probably lead to a longer life of the board.
The cooler will be available soon, and can be ordered using our complementary L'INQ. We're welcoming a test unit, so that we can either confirm or negate the scores in independent testing.

...Inquirer, so take it with a grain of salt...I don't doubt the product release, only the temperature drop claims.Quote:

* Single Slot Cooling solution (Only BFG Tech has the Single Slot Adaptor)
* Copper and Delrin design for extended life
* Multiple fitting locations for easy tube routing (Prepped for SLI)
* Of course SLI Compatible
* When purchased through BFG Technologies receive their industry leading True Lifetime Warranty
Availability - Soon
holy shikes, the BFG one is Danger Den's?
I want to see some comparisons between the BFG (DD) one and the slimeX-whatever
and i want to see the guts of the bfg one.
and I want all this done yesterday, before breakfast ...with eggs!
bfg = copper
silenx = aluminum
BOTH = Bunch of melted pop cans
So who else made em?
I found this Danger Den full coverage block over at NCIX. It is the same one that is on the BFG wc'ed 8800 GTX. They have it for about $140 US. Not in stock yet, but due within 10 days - 2 weeks. Link: here
$140?!! It better come with a pump, tubing. radiator, some kick-ass fans!! :eek:
Unless you got a card for free, the only logical solution is to buy the BFG one
Do you understand how much copper is takes to make these full cover blocks? You find the thickest point on the block, the widest and the longest points. You need a solid block with atleast those dimensions to make one block. Thats a a costly piece of copper. You've seen the news where people are stealing copper pipping from AC units to sell to scrap metal places. Copper is expensive, so that means full copper blocks are expensive. And dont forget about the machining time. Copper takes alot longer to machine than aluminum.Quote:

And since the BFG watercooled 8800 is $850+ , a regular 8800 + $140 isnt too bad.
