Needing a better GPU Cooler

Hello,

I have an AMD Sapphire Radeon HD 7850 GDDR5 2GB.

Little about the clock speeds:
Stock
Core: 920Mhz
Mem: 1200Mhz

OC
Core: 1200Mhz
Mem: 1375Mhz

This card works pretty well but its stability really seems to vary. It was stable for an 8 hour gaming test which pushed the card below 60FPS almost constantly, but now its stability seems to be declining. I've noticed the temps hitting about 70C, so I thought I might get a better cooler and try.

Does anyone know of a good cooler for a Radeon 7850? I know there was one which let you use a CPU water cooler on it, I wouldn't mind trying that if there aren't any good coolers for this card, but I don't remember what its called to find it. I think its Kraken something.

I've never heard of CPU AIO coolers used as GPU coolers, but as long as the block fits onto the card and you have heatsinks for the VRAM I don't see why you couldn't. But, the ideal way would be to set up a water loop that has either universal GPU water blocks or full card blocks. For the 7850 there is only one full card block on the market and EKWB makes it.

BTW performance drops might be the card wearing out due to the higher clock you have it set at as well. So, there is a chance a better cooler might not be the solution. Just be prepared in case.

Use the NZXT Kraken G10 + NZXT X40 Cooler, you will need VRM and VRAMs heat sinks too and you should be fine :) 
You also can just get water cooling loop with a GPU block and it would be better.

70C is OK. Sapphire coolers are OK. Leave it as is.

Thank you this is what I was trying to remember :) 
Yea I know a full custom loop would be better but I don't have enough cash for it so I'm going the relatively cheap way out.

@jdcranke07: Yea I am a little concerned it could be the card wearing out under the high clock, but I've only had it maybe three months now. I'm hoping the better cooling will keep the temps and such low enough that it will stop any wearing out of the card at these clocks, I'm not really hoping to push it higher but getting it stabilized will be nice. Bright side if I get the Kraken G10, it works on a wide variety of cards so if the GPU has to go and die, at least I can reuse the cooler later.

This is why I'm believing that the card could be dying if temps aren't really that high and performance is decreasing as he mentioned. Could be wrong though.

The extra cooling won't save the card if it is dying. Lowering the clock would do so. This is really just a hit and miss thing with OC'ing since its all based on the individual card and the quality of its make.

It is indeed the cheap way and definitely gives better temps than the stocks ones. But that won't change a thing if your card is dying already, which your card isn't really, as AMD cards gets to even more than that and it's normal and really fine.

Eh well that is true 70 isn't typically so bad, and performance is declining. I had thought it was just general instability cause I hadn't increased voltage hardly at all and climbed up nearly 300Mhz. I guess its better to be safe than sorry and just take a 30Mhz drop or so to ease up on the card than throw a cooler on it and it just hope it helps but not really being sure.

The thermal threshold of AMD GPUs is high granted (~90-100'C). But lose of performance with no change to temps, or clock and an increase in voltage means the card is starting to die. Otherwise, Your card should be fine.

Yeah i know this about AMDs, and even nVidia card gets up to 80 or 85 and it's still kinda fine specially for high end ones. But my head just tells me that it isn't, I don't like my gpu going over 60 it usually never reaches 50 and this is an overclocked 670 under water. Maybe it's just me :p

Yea see thats what I am kind of thinking. Cause like I've seen other people run the 7850 GPUs as high as 1300Mhz with 1.35v. I'm at 1200Mhz and only using 1.160v. For some reason, unlike my brother's 7850, the voltage defaults to 1.210v while my brother's defaults to 1.138v so I dropped the voltage a lot too. So while it is possible its dying cause I pushed it too hard, its hard to be sure. I think it just needs a little more voltage to help make it stable but that would probably push it around 75C and that makes me a little uncomfortable.

Suppose if its probably good until 90C I can try a voltage bump and see how that goes and if its stable get the cooler. If its dying, it will just crash faster cause the heat probably in which case I need to RMA it anyways, and if its just needing a little more juice to hold this clock then it will be fine.
