Title says it all.
 
I would like to unlock the throttle option at 70ºC, right now I can do 1250MHz Core on both GTX680's and +450MHz Memory.
 
The thing is I use a fan profile of 65%-75% to keep them under 68ºC, but I would like to use a fan of 60-65% to keep it much quieter but sacrificing a bit of temps, only problem is at 70ºC they start to throttle.
 
Is there any work around for this? If not, will there be one? I really don't mind having my cards at 70-80ºC if this means I can run them at a much quieter fan speed. 
 
Thanks.

There is no current workaround for this and looks extremely unlikely there will be one, at least for reference cards. Just gotta keep it under 70.

remmeber as die shrinks, the temp tolerance decreases...
500 series could be around 80-50 MAX
kepler's max should be 70-75 if not less
 
thats probably why they locked those points on auto curve 

Well that's a bit sad then I can't imagine once temperatures reach 40ºC here in summer I'll need to run the fan at 80% then? That's way too loud.
 
I am quite sure 70-75ºC would be fine considering Nvidia says max temperature 97ºC  just like GTX500 cards.

are you refering to Tjmax?
thats the temperature at junction ( where electrons move ) the 90ish range is true for any sillicon based semiconductor, regardless of anythign else ... but thats an abselute max, for every 10degrees C , you shorten lifespan by about 10%...
 
they are billions of transistors on the chip, if any sectors get above the Tjmax , the entire core will fail to preseve itself
 
the core temp is somewhere between juction and outside world, so its always safe bet to stay well below it.

id stay below 80 if you wish to keep the card for a while, thats why i love EVGA they let you put after market coolers as long as no physical damage was done

Incorrect. The thermal limit for the GPU on the GTX 680 is 98C as officially indicated by NVIDIA: http://www.geforce.com/hardware/desktop-gpus/geforce-gtx-680/specifications
 
Thar being said, you'd probably want to keep the card below 85.

Is there really a throttle at 70 C?  Where is that link?

You don't have to worry about damaging a CPU or GPU with heat with current electronics.
 
All modern CPUs and GPUs have automatic throttling and even shutdown when they reach certain thermal limits.
 
Intel has stated this, that heat simply cannot harm their processors.  I do not see why this would be any different for GPUs.
 
The throttling I'm talking about is not what you see at 70c on the GTX 680.  It would be the 98c that nVidia stated.  Like 105c or whatever it was for Fermi.
 
The GTX 680 doesn't "throttle" at 70c it just lowers its boost clock by one step at 70c and another step at 80c.
 
http://www.techpowerup.com/reviews/NVIDIA/GeForce_GTX_680/30.html

 
GTX 680 is a 1006MHz base clock and a 1058 Boost clock.
 
The 680 will never go below the 1058MHz boost clock at any temperature (under 98c)
 
At stock settings the GTX 680 will boost itself up to 1111MHz as long as the temperature stays under 70c.  Then at 70, 80, 85, and 95c the clocks drop down by the offset which is 13MHz by default.
 
Finally as you can see at 98c, the card finally throttles down to protect itself.
 
I would recommend getting aftermarket cooling if you want to stay under 70c for the maximum boost while remaining quiet.

It also drops voltages at those temps. Mine drops from 1.175 to 1.162 at 70c, then it drops to 1.15 at 80c. I tested up to 92c but it did not drop again.

Looks like to me you could fit 2 accelero twin turbo coolers which would not only be completely silent but would also solve your temp problems.
 
I love mine, even overclocked to 1325mhz core and 7000mhz mem my load temps after a few hours of gaming are 52c.

SirMaster, that is good information, but I think the OP would say it isn't really helpful to his question. You state that it isn't throtteling at 70c , but the OP apparently chooses to go by different nomenclature and a different definition.

The OP wants to know how to disable the boost clock dropping feature which occurs when the GPU temperature exceeds 70c. My guess is that someone at mvktech or some similar source will find a way to bypass it.

Of course bypassing it would almost certainly void the video card warranty because it almost certainly requires a BIOS or hardware modification.

Only way is to try to lower your GPU temp.

Funny. 
 
I guess I'll use a bit higher fan profile, I loved using 60% though. 

get more cool air into the front of your cards. try to add more silent airflow sources, then you might be able to avoid turning up more audible things like your GPU fan. 

I have one of the best air cooled cases for Multi GPU systems. 
 
I just think dropping the Core clock once it reaches 70ºC is a bit pathetic, considering these cards should be able to handle 80ºC 24/7 just fine. 

You know what is funny? I've resorted to lowering my fan speed to raise the bottom card temp past 70C and maxed the fan speed at 80C. That way they run close to the same speed. Except some games raise the top card past 80C but nothing I can do about that unless we get a fan unlocker.
 
But that "feature" made me run my cards hotter and not cooler and made me a bit more likely to need my 3 year warranty in the future. I'm sure that's what they had in mind when they implemented that. I'm not keen on spending $250 on aftermarket coolers either.
 
They should have designed it to drop 3 notches at 85-90C.

 Are you against switching the stock coolers to aftermarket?

$250? which coolers are you looking at and how many cards do you have?

2 cards and I have no free slot between so any aftermarket coolers would have to be the same thickness as reference.

Along with a few other Silverstone offerings, you have THE best air cooling case. I miss mine :(

It would defeat the whole purpose of the FT02. You'd have air/heat blowing all around instead of following its natural path of up...

Ah I see, room is an issue then but I was gonna say that you can get 2 very good coolers for much less than a combined cost of $250.00.  The artic cooler that I have on my 680 cost me around $48.00 and also fits the 580.

If the case has decent intake and exaust fans then it isnt an issue as it will deal with the hot air that is expelled from the coolers.

I understand that, though I'd argue exhaust is 100% irrelevant in an FT02, but I can't help but think you're not familiar with the case. I'm not saying that as a conclusive thing, but even Silverstone recommends using external exhaust cards over anything else. Even if kcuestag went with an aftermarket cooler, all that hot air would be going through the radiator and I know I wouldn't like that.

 No, I dont know that much about his PC case so perhaps for him it would be best to stick with the stock cooler.
 
For me though I have always just gone with the traditional PC case with a simple intake and exaust fan which has always dealt nicely with the hot air that is expelled from a GPU aftermarket cooler.

Well the intake is at the bottom (3 x 180mm) and FT02 is a beast :)
 
Here's my old setup - 

 
And here is kcuestag's - 

So it doesnt really have an exaust fan? I see yours did but I guess he doesnt since his is water cooled.

Well it has a 120mm exhaust above the CPU, along with anything an external exhaust is kicking out, but it doesn't matter. Positive pressure coupled with all intake at the bottom & all exhaust happening at the top means that exhaust fans would be next to meaningless. I'm not trying to argue with you, and I never got the sense you were either. It's just that having an aftermarket cooler blow everything around in a case oriented like this seems pointless when the stock cooler is doing very little work to blow it straight up. Simple thermodynamics

Yeah im definently not arguing, I completely agree that in this scenario he is better off with the stock coolers. Thanks for the pics of the case, helps me see where your coming from.

Someone over at [H], unless of course this is you lol, is having the same problems with their temps in an FT02 -
 
I'm starting to question the internals of the 680 and plan to test temperatures with my SG05 in multiple orientations. This is starting to sound similar to the after market coolers, which had no wick, that people were putting on their GTX 480s. Needless to say, they were running a lot hotter when in the 90 degree orientation because of this. 

I'm starting to question where the idea came from that you don't need adequate exhaust fans regardless of the case design. There is nothing special about that case other than having your GPU's vertical. That does little or nothing to remove heat out of the case versus a horizontal configuration. A bit more exhaust air flow does wonders.
