So would I, but if you wrap it round the card like so :




You loose out on temps as opposed to it hanging of the card with a fan blowing through the heatsink and onto the core like so :



There is a member here who has SLI GTX + Zalman VF1000 and I remember him posting that it dumps alot of heat into his case.

my vote is the zalman. check the sig rig. It's a really good cooler.
BTW leave my wire management alone. Plus like the upper has said about extra hot air in the case. I seen not temp difference on any other components. Plus you would see the extra temps from every after market cooler not just this one. since they all dump air directly back into the case.

Looks like you have a nearly identical setup to me. Wire management in the Antec 900 is difficult, especially if you have a rev. 1 case like me, and looks like you too. I'm going to make some holes on the side of the MB next time I tear the system apart, like the rev. 2 case has.

So you noticed a significant improvement with these coolers? Worth 80 dollars per card? Could you tell me what idle / load temps you get?

Thanks a lot!

I just downloaded a copy of 3dMark06 and I'm going to use that to try to warm up the cards as well as see how they test out under stock conditions.

At this point I think I have everything wanted to start overclocking and it's just a matter of getting started. ;-p

Still wish I could get that topmost card to stop idling around 60-65C and hitting 80C under medium (WoW, etc.) loads... and it's not a specific card, if I swap the cards out, I'll get pretty much the same numbers...

The 780i really makes it difficult to do aftermarket cooling and SLI.
I didn't realize it when I tried, but like you said the NB heatsink hogs the space that a Thermalright could make good use of.

I now just have a single 8800GTX with the Thermalright HR-03. I had to drop the other card, and my sound card.

It doesn't help that the 780i requires a videocard in the first slot also.

Here's a shot of just how much space it hogs up.
...It should be mentioned that I no longer worry about my temps though.

You stopped using SLI to cool one card?

I'm thinking about replacing the stock coolers on my two 8800GTX cards. My case is pretty full with these two cards and an x-fi. The NB heatsink is also huge, being a 780i board.

The GTX's are by far the hottest thing in my case at the moment, idling at 50-60 and load up to 82°! I understand that these are normal and safe temperatures for 8800GTX's, but I'd like to overclock a bit more and for that I need better cooling!

I don't really want to get watercooling, that will be reserved for my next complete rebuild (perhaps in fall, when 9800GTX can be had for less then an arm and a leg).

So my question is what aftermarket air cooling can I get that still fits in the two slot profile of these cards, but provides me with good cooling? Recommendations, anyone?

Set your GTX fans to 80% man and get that middle fan in on the 900.

Yes.
With both together, using the stock HS, I wasn't comfortable with the level of temperatures I was hitting.

I'm using the other GTX at work though, until I decide to try to cram both in there again.

If you have too much trouble you could check this out.

The top card sits at around 46 c, just hooked up to the motherboard no fan controller. but the true reason I went with these coolers was my bottom card with stock cooler on it was hitting 85c. With this cooler bottom card is hitting mid 60's. god I swear this power supply is radiating heat, or cusing airflow issues to this card. "I NEED A NEW CASE"
