No thx, i like it all black, oh and no money, big joke.

Thats a nice sink but i think this way is a lot better, oh and this is a 480 btw.

max temp. while playing BC2 fullhd high aa8 was 61ºC 800rpm fan.

Yea I knew it was a 480 but the stock unisink is not by any means better than those copper sinks. If you're happy with what you have then that's good, especially if you can't afford them right now. But those sinks would allow you to use more voltage and have your VRMs stay cool, that's what I meant by taking advantage of the better core cooling, you could push enough voltage safely through your VRMs to OC your core higher.

It was a joke, ill think about that.

hmm, thx for the tip, i forgot to say that i had 61ºC with 880 core with 1.1v.

Sure NP, just be aware that you will definitely need to hack that one big copper sink into smaller pieces as needed to fit on your VRMs (won't be difficult copper is a soft metal, so you could even just use a good pair of scissors) and you might also need two of them to cover all your VRMs but you'll want to measure to be sure.

And just to be clear cause I thought of a better wya of explaining wha tI meant, if you're currently loading at 61C in games and your GPU core is good up to over 100C then you have plenty of headroom available to you with the cooling on your GPU core, but if currently you applied more voltage as it sits now then your VRMs would be insufficiently cooled for the task and that would hinder stability and not be very safe. With those heatsinks you could safely turn up the voltages without worrying too much about either your VRMs or GPU core, you'd be able to use voltages nearly as high as people on real water.

I'm gonna look at a PCB shot of your card and see if I can guesstimate if one of those copper sinks would be enough.

EDIT: Mmm it's be close so you'll probably want to measure yourself because you might need two, but that copper heatsink would be a great improvement over the stock unisink.

You sir are more interested in this then i am LOl

But ill have to think about that, cuz i tested 900 in the core with the original fan at 100% and the radiator at 1500rpm and i couldnt get stable even with 1.150v, so maybe its not that great unless i want to change the aesthetics.

Well that's the thing with voltage that high it could very well be your VRMs overheating that is introducing that instability. The thing that is "not that great" is the cooling that unisink is giving your VRMs.

And yea I'm a big fan of cold VRMs, and I was considering ghetto mounting something like a H60 to my Lightning with a couple of those heatsinks. But I'm not sure A) how a H60 would do with the heat of a 580, and B) if it's worth the $90 dollars it would cost me over what is already a pretty good cooler in the TFIII. I'm also not jumping at the idea of having water in my case, especially because I'm sure if something did happen Corsair would blame it on the fact it was on a GPU and I'd be on my own even though I wouldn't be modding the H60 at all.

I'll be sure to remember this when you post that your card popped. Also way to derail your own thread with a troll post as soon as it got somewhat productive.

Uh-huh. I already put sinks on the vrm's, what's the big deal? The cooler itself? It weights 500g, zalman v3000f is 430g, accelero extreme ii is 900g. There are heavier coolers.
