The Ultimate 8800 GTX water cooling solution!!!

[rjw]

Check this out and tell me what you think...

[K404]

I want. How much, who from and whens it out?

[guess2098]

is it smileing at me?

wat a happy face hehehe

Pleas tell me what you think, first?

Check out the size of the water block portion

[Equil|briuM]

You do realise that BFG have a preattached version.

Im not entirely sure of its performance,though.

[p0tter]

it smiles cause its wet...

I have dd water blocks for a pair of 7950 gx2's and I am aware of the dd/bfg solution as well...

Just throwing out something that may be better, I don't know yet

The water block flows more water, I think...but I'll know soon enough how it works.

Working on the sli solution at the moment...

[J-Mag]

So the channel walls are acrylic and not copper or are my eyes deceiving me?

[Mr. Popo]

Can you say "bad flow"?

[rjw]

Can you say "bad flow"?

why bad flow?

The picture is deceiving. the water channels are large and the walls are thin and made of polycarb.

It flows a lot more water than my dd gx2 wb

The copper plate is quite thin and should transfer heat to the water well.

The underside fits all the chips, gpu, etc perfectly, unlike the oem solution which uses some heat tape of some sort to make up for the clearance between the top of the chips and the aluminum fan base.

A test fit showed perfect contact with ALL the components.

Is there a GTS version?

[thunderstruck!]

Can you say "bad flow"?

That's not bad flow. This is the least restrictive block so far. Very wide channels and simple direction.

[Charles Wirth]

With the channels not being copper would effect heat disipation some.

It needs some pits or grooves in the copper channels to improve heat transfer and add surface area.

[rjw]

my dd gx2 blocks are just a big open cavity, with some small raised copper fins only about an inch long in one area near a barb for flow direction I think.

the block on this one is much larger than the dd gx2 solution, but not sure when compared to their 8800 offering.

Also, the channels on this block are higher, and therefore it flows more water

if you look carefully at the channels, water that passes thru the shorter channels moves quicker than the water that flows thru the longer ones.

guess where the shorter channels are placed with respect to components on the board.

Bingo

Right over the gpu.

so it seems that as the gpu probably gets the hottest, its cooling water flows quicker than what is over the mem chips

This is also being looked at as a base plate to cover all components and possibly allow users to blot up their existing solutions, such as one or a pair of mcw 60's

[MaxxxRacer]

the base needs to have the fins, and not the plastic.. also, change the plexi to delrin.

over the gpu, adding some more fins with half or quarter the thickness of the other channels.

[rjw]

I realize that more copper in the flow is better, but this may be suffiient, not to mention $$$

if you read , I said polycarb, not plexi.

polycarb is as good or better than delrin (acetal)

[wtkprol]

Yea, I suggest putting some fins or channels around the GPU area and the "smaller" GPU core.

[D_o_S]

Is it just me, or are the barbs on the wrong side?

[XS Janus]

maybe he just has a lian li case that mounts the mobo upside down

Charles and Maxxxracer are right. The channels need to be copper, unless you're gonna use this as a chipset cooler...

[Nanometer]

I'd like to see copper, double the channels, and smoother channels for that matter. I don't think I will be water cooling this card anyways, but it's nice to see new blocks.

[alexio]

In the best case it will be worse than the stock cooler. In the worst case, and the most probably, the core will overheat. Let's hope thermal management works okay on the G80.

I'm sorry that I'm so negative, but you really need much more surface area above the core.

[septim]

mill some groves above GPU area?

the front or back side with regards to barb placement would be nice addition to it

[rjw]

Thanks, everyone for the input

I am making changes

btw an mcw60 on this board runs at 53c full load (stock voltages)
