Ha! Have fun w/ those like I know I did this past weekend. :D

Word to the wise: make sure you don't do a dumbazz thing like I did and get the inlet/outlets on there the wrong way. I had to drain all the coolant out of my loop and rearrange my fittings. Both can't be on the same end of the card (left/left, right/right), otherwise water won't flow through the block. They can be on the same side, I believe (top/top, bottom/bottom) but not on the same side of the card.

I lost that piece of paper that came in the box showing the different configurations for the fittings and ended up calling BFG tech support and asking what ways I could align the connectors (could never get Dangerden on the phone). As usual, their "tech support" was useless as I ended up talking to a general customer service person who didn't know a graphics card from his @^$. He put me on hold while he went to go check his computer or supervisor or whatever, and then told me, wrongly, that the connectors could be arranged in any way that I wanted. When I asked him then why my graphics card was running at 78C at idle with the way that I had it, he seemed baffled and said "Well.. these cards do run hot..."

Toolbag. I rearranged the connectors and now I'm idling at 45C.

You overclock it? What are you seeing for stable temps and benchmarks?

Sweet!

Dren72: Haven't overclocked it yet. My machine is down temporarily while I find a solution for the southbridge cooling.

But when I benched it with Oblivion the temps never got over 56C on the card. That's at 1680x1050 res, 8xAA, 16xAF, all sliders maxed.

Finally got the waterblocks mounted on the video cards. Amazing how much longer everything takes when you have children and you're the only parent in the house today. Anyways, here's a picture of the work in progress:

Nice cards and blocks! But the wiring could be improved ;)
Wiring is definately my next project. I do have quite a few things running in this setup, so it's going to be a challenge.
Here are the before and after temperatures on the gpus at default clocks:
Stock cooler idle l stock cooler load l DD waterblock idle/load

GPU 1: 69-70 l 79-81 l 42/45

GPU 2: 65-67 l 75-77 l 45/57

I ran rthdribl for several minutes to place a load on the video cards and I observed the temperatures through nTune. As you can see, there is a significant drop in temperatures at both idle and load with the Danger Den blocks. Not only that, but the ambient temps in my case have also dropped trememdously. Before, I could just feel the heatwave coming from inside my case! Now things are much cooler and needless to say, the components around the video cards are much cooler as well.
I should also mention that I'm using an EXOS2 external watercooling unit to cool the video cards. I'm very pleased with the results the Danger Den blocks have provided, and my next stop is overclocking.

Hmm with stock cooling my 8800GTX runs @ 57C idle havn't looked at what it's like under load yet.

looks awesome! with a lil wire job it would look awesome

idle temps mean nothing. it's all about the load temps.

Thank you very much. I do have a few things coming to improve the wiring:)

I think they do, too me it means that the air flow is not good enough to them down and if it's hot in the case then load temps will be alot higher also.

Isen't the G80 on idle have very low clock speeds?

if it's hot in the case then you've done something wrong and of course at that point load temps will be higher. I don't need idle temps to tell me that you can tell by using the air flow and your hand.

I thought the same but i just checked clock frequency settings both 2d and 3d of my evga lists 576/1.8Ghz, so I guess not.

Very nice indeed :beer:

You don't know where a person could get a pair do you?

As far as I'm concerned idle is just as important as load. You need to have both temps to accurately guage your cooling performance. If the idle temps are low, it means you have good airflow and the cooler is working properly. If they are high, you may need to adjust something to make them lower. Then you can compare the load temps with the idle temps. If they are close, it usually means the cooler is doing a good job. If there is a huge spread, then it means that you need a better cooling solution.

A good example is that on idle, I could probably run my 3800+ without a fan, and the temps wouldn't be that high. Obviously, as soon as I start cranking on it, the temps are going to skyrocket. If I didn't know what it idled at, I might just assume that it runs as hot as it does at load.

How about your CPU temp after you got a pair of G80 in your wattercoolingsystem, it rise a lot??

I have a Swiftech MCW5002-775 Peltier block cooling my cpu on a seperate water loop, so I don't have to worry about rising cpu temperatures. I'm thinking about adding northbridge water cooling to the cpu loop though, since the northbridge on the 680i gets very hot. If I do this, the cpu temps are sure to rise.

The only place I know of that is currently selling these blocks is Danger Den directly. You have to pretty much check often, as they seem to be selling out almost immediately after posting stock.
