I recently bought an EVGA GTX 760 SC ACX (02G-P4-2765-KR).
 
I was expecting a really quiet fan but... it's a mess. So I started tweaking the fan profile on EVGA Precision X. Here's what I've come up with:
 

 
I did some temperature tests with OC Scanner:
 
GTX 760 ACX (default fan profile)
Idle: 26ºC (43%)
Load: 71ºC (64%)

GTX 760 ACX (custom fan profile)
Idle: 25ºC (45%)
Load: 72ºC (62%)

Explanation:
 
1. <50ºC: At the lowest setting (default idle fan speed), which is 43%, the fan emits a noticeable humming. If you have quiet fans on your rig this is really going to destroy your acoustics (I have 3 Nooctuas, two running at ~1.000 rpm and one at ~500 rpm and also 2 Antecs that came with the case connected with a couple of 5V adapters at ~500rpm (they barely move any air but I leave them on because they're virtually silent at this voltage)). Suffice to say the loudest noise coming from my case is the case vibration from the HDD spinning at 7200rpm.
 
TL;DR minimum fan speed needs to be set at 45% at all times; you get way less noise (humming) and better temp (-1ºC).
 
2. From 50ºC to 65ºC: The default fan profile is a little too aggresive, the ACX coolers have pretty good thermal performance, with a lot of games we don't even reach 65ºC. I start to increase speed a little here to smooth things out, because with more intensive games we will get into the next stage (>65ºC). There's a jump from 50% to 55% fan speed at 55ºC because the humming is terrible at 51%-54%. From 55ºC to 65ºC we stick with 55% speed because we will spend a lot of time here while playing.
 
TL;DR we want the lowest noise possible and to avoid "noisy" fan speeds
 
3. From 65ºC to max temp: We will rarely reach this stage, but to optimize the temp/noise ratio we just make a linear curve here (65ºC - 100ºC -> 55%-90% (1ºC = 1%)).
 
Final TL;DR: The default fan profile is mediocre at best, we can make the fan a lot quieter without any noticeable impact in cooling performance by tweaking it with EVGA Precision X. Feel free to try mine and I hope you like it.

I took another look at the new bios thread and your particular model is not listed. But I would check anyway, they may have released one for
your model by now.
 

I think that they may have released the new bios for the dual models first just in case there was a problem with it. If there is a problem with the bios then
you can change over to the other bios. Since EVGA recommends flashing the second bios and keeping the primary at the default state, if there is a problem
then you can switch back to the primary bios. I think that if this new bios works with the dual models then they should release it soon for the single bios
models.
