I know this has been posted a few times before for the 780 cards, but I'm also extremely disappointed in the high minimum allowable fan speed on the ACX 760 card. This thing idles at 23°C, and at 43% fan speed, is probably 15-20dB louder than the rest of my system. This makes this the coolest-running at idle card I've ever encountered, and the tradeoff is that the fan noise is a LOT higher than it needs to be at idle.
 
If anyone at EVGA reads this, can you please pass on my request to release a BIOS that doesn't have an artificially restricted minimum fan speed? I've read about 780 users flashing to the Gigabyte BIOS and running @ 17% to fix their issue, and I'd like to do the same but I haven't come across any 760 owners that have tried this or that can recommend an equivalent non-EVGA BIOS.
 
Lastly, as a pre-emptive comment to those that claim that "the ACX cooler is soooo quiet they can't hear it", etc.= If you think it's quiet then I'm happy for you. Odds are you either have lousy hearing or the rest of your system is equally loud, in which case this thread does not concern you. Please do not litter this thread with some sort of misguided defense of EVGA's honour. The facts are plain as can be: the card idles extremely cool @ 23°C and I perceive the fans to be way too loud, so there is a LOT of thermal headroom, and there should be no physical reason for not being to run below 43%.
 

Thanks for the suggestion. I just tried it and it has the same lower limit as the EVGA software (it looks like both are the same software, but with a different skin). It seems to me that this is something that has to be fixed at the BIOS level.

You have to remember that 43% idle is so the card doesn't overheat worldwide. Lots of parts of the world run hotter then others. so thier needs to be a minimum safe temp for the cards to run at.
 
Not everyone has air conditioning
 
You also have to account for other components in the case running with the card as well that throw off heat or when running in a SLI configuration.

No bios flash options for those who would like the ability to lower the fan? Does the 780 also run at 43% min?

 
dunno about the 780, but my 770 does.

Must be WC to even notice 43% fan on ACX. I know I have a blower 680 but I can't even hear it at 60%. ACX really that much louder? Trade your 760 for a 670, problem solved. lol

Sounds like the bearing on the fan are bad. I can't even hear my GTX 780 ACX when at 60% (loaded)... It's very quiet.

I don't know about flashing options with other vendors. I was hoping someone on here might point me to one that will work.

So far, I've edited  my stock BIOS with Kepler Bios Tweaker to lower the Min fan speed (it incorrectly read my BIOS' min as 20% and max as 70%) to 5%, and flashed but in Precision this didn't seem to affect anything as I can't go below 43%. Other utils such as GPU-Z also show 43%.

You might try using the Kepler BIOS tweaker again using a value of of say 30%. If you put in a value out of range the GPU fan controller will ignore it.

evga sent me a BIOS that reduces the fan speed to 38%. Unfortunately, it doesnt seem to be working as intended. I get 1200rpm instead of 1230. It should be around ~1100.

I told them about this issue, hopefully we can get it resolved.

 
1 post after registering back in 2009? welcome to the forums

I have this problem with my GTX 770. Fan speed is always at 41% at idle. I really regret buying this EVGA card, the cooling is decent but it has a stupid fan profile.

Well the thing is they are 'apparently' working on a BIOS update that will take the fan speed down to 33%. They are just taking too long about it.

Apparently the reason why the fan speed is set so high at idle is that if it was set too low, then the fans would not be able to spin at a higher RPM when under load. Personally, I think that is absolutely stupid, why is there a limitation like that but hey I'm not the one making the product.

No it's definitely not a Nvidia limitation. I don't know why EVGA are taking so long, but I guess all we can do is wait.

When the update comes out then it'll make my machine ALOT quieter.

I posted on the forum about the noise issue (on this account) and opened a ticket. They said the same when I opened a ticket, but they sent me one a few days later. I mean I suppose I can upload it in a zip file... but where?

 
I'd appreciate it if you could. Every bit helps...
Do you have skydrive/dropbox/google drive?
 
I got a further response claiming that "any lower than 38% would cause the card to fry or fail". If it happens, this'll be the first piece of electronic equipment in history to fry at room temperature... very disappointed with this card, indeed.

Does it work? Just run the update.exe

I am not responsible for anything if your PC explodes or whatever. I am not sure if evga will be since the release doesnt seem official.

 
Unfortunately, it says my card is not compatible with this update. Thanks for trying, though. I'm sad to say, that's a lot more than I got from the official support.

I've tested the ASUS GTX 760 DCII Bios yesterday. 
With this Bios I'm able to lower the fan speed to 29% and 1200rpm. 
In this Bios the minimum fan speed is set to 10%.  If I try to set the value of the default EVGA BIOS to 10% I'm not able to lower the fan speed.

So it seems as if the EVGA card is locked/not able to get under 1200rpm with the ACX cooler..... 

A official statement would be great. Will EVGA release a BIOS we would be able to lower the fan speed to 1000rpm for example?

1200rpm is still quite an improvement...
 
 
Where you able to get 100% max fan speed without problems on that BIOS?
