I remember that thread for the 560ti lol. I concluded it wasn't worth it, mostly because while my temp does dance in the 60's, I deal with instability rather than a heat being the core issue.

Also I don't know if the rest of the card would be fine or not if you put the h80 on it. My msi model seems to be mostly open unlike the stock heatsinks.

Yes zip ties.

But honestly if you do it right you don't even notice them. And zip ties are perfect as they are quiet robust and have a little bit of stretch to them. They work better than you would imagine. I won't hesitate to do it this way again. I used black zip ties went around the ear of the coolers tabs, then out the back. Then use the head of another tie to cinch each of them down. Once the ends are cut off its hard to even see how its mounted.

Edit; Also, the ram wasn't cooled before. So, I ordered some small heatsinks to bring the temps down. So they should be running cooler than they were with the stock coolers on. The VRM's already have heatsinks on them. I have a 140mm fan pushing air over both cards. I took my time to make sure it looks nice. And honestly, it looks really great. With the LED's of the h80's it looks way cooler than stock, that's for sure.

And even after 5hours of gaming on BF3 my temps never exceeded 44c on either card. My OC's went up quite a bit too. As did my 3dMark 11 scores. 3dMark11 score went up over 500 points just by getting the temps down. The mod cost less than half of just what the blocks would be to custom cool (not counting the rest of the system), so I'd say its a great deal. Plus, if I have a failure, I will only lose one card, not both cards, the cpu and possibly the whole system.

I would have figured if my card isn't breaking 70c the temps would have nothing to do with the stable OC, but you could be on to something. Wouldn't mind trying this if I was more confident it would would on this card (and that there would be enough downward force on the gpu block).

I can guarantee you plenty of downward force is put on the GPU block. If you wanted to you could deform the PCB by putting so much pressure on the zip ties. They really are that strong. What I did was to carefully tighten in a cross pattern, holding the tail that comes out the back of the card and pushing the head of the zip tie into the back of the PCB. All of this is done from the back. You can hear the zip tie click as it grabs another cog on the tie. Then you go cross pattern to the other side etc. Until you are comfortable with the pressure. I used a pliers to pull the tail while pushing with my thumb and forefinger on the head of the zip tie. So, like I said, you could literally deform the PCB if you wanted to, but obviously there's no reason to do that.

Once you try it you'll see how robust it really is. Its one of those things that can't be believed until its seen or 'felt' if you will.

Once I get my RAM coolers set on I'll post some scores. Right now I"ve got a run at 19.7k on 3dMark 11. I realize that's not groundbreaking but its over 500 points better than I could get before the h80 mount. I'm hoping cooling the RAM chips will allow me to push the mem higher and then get above 20k.

If you don't want to use the zip ties, the nzxt kraken g10 dwood style bracket is set to drop any minute for like $30.

Okay, for those of you who want to know what water can do....

Here are my results before going on water. Running +66Mhz on core +275 Mem

That's a score of 19,124 on 3dMark11. I got a score of 19,123 with -20Mhz on core and -20Mhz on memory when the h80's were installed.

And here is after installing the h80 in both my SLI GTX670's . Those are the same settings no difference whatsoever. The only thing that changed was the core temp went from 62C down to about 39C. That was all. In fact here's a run at -20 on the core and -20 on the memory.. That's 19,123 at a -20 on core and -20 on memory. And it got just one point less than +66Mhz on core and +275 on memory.

So by adding the h80 to the 670's it dropped the core temps down by about 13 to 14C while benching. The results are impressive.

I don't think this is done yet. When I get the RAM heatsinks installed I'm betting I can push this further. These were just some really quick runs I made.

how do you get such high 3d mark scores on a 670?
Mine on a 680 OC'ed with +55core clock was 11k.

Also I think it might be worth for the OP to mention this about kepler OC:

I figured this out with the help of an OCN poster via a site where you upload your bios + the kepler explanation in the OP.
My Kepler boost is 195mhz.

This is SLI man. I can only get around 11k on one of the cards too. No worries, you're fine. I have an older chip, so I'm somewhat bottlenecked on the PCI-E which is why I'm having trouble getting above 20k, but the water is where its at from what I can tell.

stating + and _ offsets mean nothing. you have to tell us your clocks. every card boosts different and has different clocks.

nobody helped you figure that out. thats a false understanding of how the 2 different boosts work. i pointed this out to you. as i said in your thread, go look at my attachment in your thread. there is NO way a crashed driver will let a card run at 1402mhz but yet heaven4 showed my card was doing just that. and my card wont run anywhere near 1400mhz anyway.
i sent sean a pm to come to your thread and explain how it all works.

and those arent single 670 scores. he runs sli 670s

great looking forward to it. In the mean time, get out the house and chillout. There's no need to act like that lol.
