The stock BIOS that came on my card allowed me to go as low as 26%, but that's the best I've seen so far.
Not sure what you're asking here, but the heatsink is mounted perfectly fine. Temps are great.





It's just the EVGA ACX cooler with the fans swapped for much, MUCH quieter ones.

Oh, I'm sorry for my bad choices of words.

My point was that it might not be able to go that low, or that the fans need a specific voltage to spin. And below that voltage value they won't run? It's just a thought though..

*edit*

Forgot to mention the thing about the spool-up of the fans. I've had no luck on google nor the swedish forums. Sorry mate, hopefully someone will be able to tell you in what direction you should look when it comes to the fans spool-up/down.

Last night I decided to investigate why one of my 780 SC's runs hotter than the other. Both were bought brand new from Newegg. The one that runs hotter has 2 missing RAM chip thermal pads (they just aren't there) and a bent HS fin... what gives? I redid the thermal paste on both using NT-H1 and ordered some FujiPoly pads... kinda irritated. Now with the better paste the bottom card actually starts running a degree HOTTER than the one on top... that can't be right. Just from 2 RAM chip thermal pads?

No two cards are alike, each chip has it's own characteristics. While you'll want to get some pads on the vram, it probably isn't making a bit of difference when it comes to the core temp.

If I could just get the card to accept the low-RPM of the new fans, It'd be perfect. Still holding out hope that someone can mod the BIOS and make it happen... Apparently, everyone who has tried to run an Accelero Twin Turbo II or an Accelero eXtreme III on their GTX 780 has run into this exact same problem, so it's not just me who needs this fix.


Those fans have a PWM controller right? And are connected to the motherboard or the card?
If to the motherboard you have to set the speed through the bios, if its to the card, the own fans PWM is interfering with the bios fan settings and/or not recognizing the fans properly!
Another thing is some features are particular to any bios, specially the ACX bios or any dual or triple fan cards; the size, airflow and fan voltage is encrypted differently than in a single fan card, that's why so many people are having hard times with aftermarket cooler with different types of fans like you do!
To find that particular string code in the bios is like finding a needle in a hay stack, sometimes we have to stumble on it to find it! No luck until now... redface.gif

Finally got a new card replaced my old MSI GTX 560 ti! Thank you guys for answering all my questions! Love my new card runs BF4 perfectly at 1440p I was surprise! What's the first thing I should do to it besides of course updating the drivers? lol

I thought I had made up my mind on returning the 780hof cards I received (as oem that were supposed to be new). Amazon was giving me a % off of another purchase and they had the 780ti classified at 762.99. So in the time I was on the phone to get the deal done they jacked the price up to 984.29!!! So now I am back to square one. The deal they are giving me though is good enough to consider a Titan Black Superclocked, and just wait til next gen or later to get something to sli. The stipulation with them is it has to be sold by Amazon for me to get a deal so that rules out almost everything but vanilla cards unless I step down to a 770 classified that has no full cover blocks made. Guess I will be waiting a bit longer and see what else they stock up on during my return window.

Wow, since I'm not a coder, I really didn't think how much work you guys have to do on all these modified Bios's until I read your post.

Even something as simple as stock cooler vs 3d-party coolers, it looks like it's a tremendous effort.

You (& Skyn3t and all other members involved) have earned my respect long time ago, but now after getting a glimpse of the amount of time you guys spent on us & this community, that respect just got quadrupled.

Seriously Thank you for all the hard work.

Hello,

I just flashed my MSI Twin frozr 780 OC with skyn3t's bios 80.80.21.00.1c and get weird flashes all over unigine heaven benchmark when I overclock.

Before skyn3ts bios I could run steadyat 150+ (1157) core and and 400+ on memory.

No I get artifacts already at 100 memory.

Also Power consumption was lowered by approx 40%. Used to have 100 now 60.
