Hi,

I've bought a Leadteak 6800GT graphics card and now I'm looking into what options I have for watercooling (silencing) it.

In two other threads on this forum I saw the Koolance GPU-180-L06 mentioned and had more or less decided on buying that, but unfortunately it doesn't seem to be available in Denmark so I'm looking in to what other options I have. So far I've been able to find these products to be available:

Danger Den - 6800 Water Block (Extremely high price, so I'd rather avoid that)
GFX Alphacool GP-NV40 6800
GFX Alphacool NexXxoS GP2-NV40 6800
GFX Alphacool NexXxoS GPX-NV40 6800

All of these should fit on a 6800 card, but the problem is that the Leadtek did not follow the reference design when making the 6800GT card so I'm unsure as to whether the aforementioned waterblocks will fit or not. Also, I've no idea on how they will perform (ie. will I be able to OC the graphics card?).

Can anyone provide me with some answers?

They did not use the reference fan.

All the screw holes are in the correct position(checked it to an eVGA 6800)
 
Innovatek also has a block, but its about the same price as the DD block, so you probably dont want it.

You dont know anyone stateside who can buy the Koolance block, and ship it to you? Its just like $40 over here. I have no idea about the currency exchange rate, and shipping though. Might not be worth it.
 
#2 You 100% sure about that? Everyone else I've asked says that the holes are not in the same position. Do you (or anyone else for that matter) now the distance between the holes on the Leadtek?

#3 Unforunately not :/ I was thinking of buying it directly from Koolance, but they charge $64 just for shipping and about $40 for the cooler.

Ohh, and btw. I found another block Heatkiller GPU Rev. 2.0 Uni by www.watercool.de. Looks like it might be good too..

As mentioned above, I compared it to an eVGA 6800, which runs the refernece fan.

Both boards use the same layout.

If my camera wernt broken I'd post pics.

EDIT: and that water block you mentioned only covers the core... so you will still have to worry about the ram
 
I see, well that's excellent news!

Shouldn't heatsinks be enough for the ram?

Technically yes, but I personally dont sit well on the concept of using just ramsinks to push memory to 1+Ghz speeds
 
Seems reasonable :)

Hmm, what are the options for cooling the ram besides ramsinks?

The only other real option is the water setup.

If you cant afford the innovatek block, then you may as well use the ramsinks.

Id like to see a modder find a way to safely slap a TEC on the ram tho :cool:

I feared that :/

Well, I guess that means I'll have to rely on the ramsinks.. Now, to decide which waterblock; Koolance GPU-180-L06 or Heatkiller GPU Rev. 2.0 Uni
 
I'm pretty sure that Swiftech also makes a GPU cooler that has an adaptor kit to work on a 6800GT. This is just for the GPU however so you'd have to do something else with the ram.

As far as the ram goes, correct me if I'm wrong but I was under the impression that water cooling the ram did next to nothing for it and that you were better off just getting ramsinks and a GPU block.

I think they're only good if you have it on its own loop. Ever since putting the DD NV-68 on its own loop using a 370GPH pump and a 86 Chevette heater core, I'm getting awesome temps.

Here is a shot of the low temps I'm getting.

6800ultra_temp.jpg


Although the Window pane says it's a 6800 Ultra, it's really a BFG 6800 GT OC that has been flashed to the latest nVIDIA BIOS revision--the v5.40.02.15.12.

The temp monitor screen is from Rivatuner.
 
Ok, I've decided on a waterblock + ramsinks.

I've got these waterblocks to choose from:

Swiftech MCW50 (need an adapter to fit it to a 6800 right? Is this the correct adapter: http://www.studiedata.dk/gfx/vare/WCSW153_medium.jpg ?)

Heatkiller GPU Rev. 2.0 Uni (It's made by Watercool: http://www.watercool.de/ - Image here: http://vcore.dk/images/HK-GPU-uni.jpg)

GFX Alphacool GP-NV40 6800 (http://www.pcmodd.dk/Cart/images/12251.jpg)

GFX Alphacool NexXxoS GP2-NV40 6800 (http://www.pcmodd.dk/Cart/images/12249.jpg)

GFX Alphacool NexXxoS GPX-NV40 6800 (http://www.pcmodd.dk/Cart/images/12250.jpg)

I'm not sure which one to pick or maybe even wait for Zalman to release a waterblock that'll fit 6800 cards. Any ideas?

Err, that's not the MCW50. That's a Swiftech CPU waterblock, the 5000 if I am not mistaken .. that won't fit on a 6800 or any video card without some nasty mounting hacks.

This is what the MCW50 looks like ..http://www.cuttingedgecasemods.com/h2o/swftcmcw50uangl.jpg

.. then there's a 6800 adapter which you must buy separately. As for Zalman, I am not too thrilled with their waterblocks. Their CPU one wiggles around under the clip which is extremely hazardous and causes massive temperature variations.

The image I was linking to was a MCW50 adapter, at least that's what the store (http://www.studiedata.dk/productitem.asp?id=WCSW153&Fane=LAN,WCVGAC) call it). But perhaps it's the wrong adapter?

They have two versions of the MCW50:
http://www.studiedata.dk/productitem.asp?id=WCSW053&Fane=LAN,WCVG2

and

http://www.studiedata.dk/productitem.asp?id=WCSW054&Fane=LAN,WCVG2

and that's about it.
 
The adapter you showed me has a picture of the CPU waterblock. This store is quite confused and I wonder if they are reputable, and will send you the right products at all ..

You showed me the 5800/5900 FX adapter-- this is NOT the same as the 6800/NV40 adapter. This is a completely different layout and will NOT fit on the 6800.

The 2 varieties are MCW50 and MCW50, Thermoelectric. The Thermoelectric/Peltier model uses a TEC drawing insane amounts of power from the PSU, requiring insulation from frost and condensation, etc. The TEC model has 2 wires coming out and a large amount of foam padding. Buy the NON-TEC (normal) version.
 
I have the MCW50-T and I love it. I just ordered the mounting bracket for the 6800, but it is designed for the plain MCW50 so longer screws are required to mount in properly with the -T version.

As soon as I get a new 6800gt from RMA I'll let you know how it works.

As for power requirements they certainly arent "insane" only about 6-7 amps I think, However if you allready have a 6800gt using insane amounts of power I would suggest using a 500 watt PS.

As far as condensation proofing a thin layer of silicone or someother dielectric barrier will do the trick. Temps really won't get much below ambient with that GPU and a CPU in the same loop. Furthermore my CPU temps only went up by about 7c which I don't mind at all since it didn"t affect my CPU overclock at all.

They're actually very reputable.

Ok, unfortunately that's the only adapter they have :/ I guess that means that I'll have to look into the other options then, but thanks a lot for your answers!
 
Found a few more waterblocks:

WaterChill DYO, VGA Cooler with Elbow Fittings, 10mm tubes
WaterChill DYO, VGA Cooler, 10mm tubes
Waterchill VGA Cooler, Version 2

All by asetek (www.asetek.com).

I think I'll be getting one of those :)
 
Thanks 12 Axes!

I think I'll be getting one of the WaterChills though since the adapter to the MCW-50 isn't available in Denmark unfortunately :/

Anyone have experience with WaterChill?
 
Happy to Help

From what Iv'e seen those smaller diameter low flow setups are really popular in Europe. I have seen some of the setups do fairly well coming within 3-4c of a high performance high flow system, and there is no doubt they are better looking.

I would really like to try one out sometime however I don't want to go through the expense of purchasing all new components.

Perhaps try a new thread asking about waterchill components as I know several people have them.
