Thanks EVGA !

Works great, thanks. 100% fan will come in handy for benchmark runs.

I'm not at my main PC right now, any news on how it sounds at 100%?

 
Same as a GTX 480 basically. The fan runs at 5200-5300 RPM at 100%. The good news with the GTX 580s is that 100% fan isn't needed unless you significantly increase the voltage and clockspeeds. (like for benching runs on Vantage)

Works great. Thanks Jacob!

Whats the difference between EVGA's and Falcon_CMH modd?

falcons is 25% fan to 100% and evga's is 30% to 100% (falcon knows what he is doing, and if he can mod the bios, think of the other things he can do....:)

Not sure, but there is a lot more to a fanspeed unlocker than just a minimum and maximum, there was a lot of work done to ensure that the fan curve stays as close to NVIDIA reference fan curve as possible.

 
Thanks Jacob for providing that info.

For SLI card's it should detect both and also flash both.

works as advertised! hopefully i can bench soon.
 
100% - 4950 rpm

Awesome.  Thanks EVGA.

I don't own a 580 yet, but.. thanks EVGA for providing this to the folks who asked for it, no company would take the requests that users wants from thier threads, that's what makes EVGA so special, if someone can't appreciate that, then I ask them to go ahead and buy from another company and see the difference.

wait, is the 30% idle fan speed the default speed set in bios now regardless of using precision or is it still 40% idle with the manual option to set it lower?

i was under the impression that the 30% is the new default idle fan speed.

It depends on the GPU temp, if it is low enough you may see 30%, but it is unlikely at auto setting.

I guess what he might be asking is the default auto fan speed still 40% as it was and you can lower the speed to 30% using a 3rd party app or, is the new default auto fan speed 30%?

So do we need to flash each card separately in SLI?  Do I need to take one out and then flash the remaining card and then take that card out and flash the other one?  It will not flash both at once correct?  Thanks

According to what was posted,  you can flash both cards with them installed.

Maybe im missing something, if the cards don't really run low enough to call for 30% at idle why would one run it at 25%?

Some are willing to accept higher idle temps with lower fan noise and they can do that manually or with a custom profile if they wish. I'm currently awaiting my 580 step ups so I can't personally vouch for the noise level at various fan speeds. However, I can hear mine just slightly at 40% on my 470's.

I want to do some tests with this new bios but can u post the original bios please?

Thx.

Good point.  Is there an easy way to flash back to the original?
 
Don't get me wrong, I love the idea that you (EVGA) are taking care of us.  I've just not run into any problems with the original bios and fan profile.  Now, I'm not benching at extreme overclocks either so those that are will really appreciate this.  For me, and what I do, it's not really necessary, but I want the option just in case I decide to get back into a few benches.
 
Thanks!

ya i flashed this one and I didnt notice any difference in fan sound at 30%.   And thats saying a lot because the only other noises I have are my 2 noctua fans on radiator and my pump and they are barely audible.  I guess the video card fan noise gets drowned under those.  
 
Id like to go back to the original since my card did go up 5C with this flash at idle.  To me thats more important especially since i cant hear a difference.  Props to NVIDIA for a really quiet fan on a monster of a card.  And thanks EVGA for offering this bios, your awesome.
 
So right now, also waiting for the original bios please :)
