I don't see the danger as long as the fans are working when the GPU is under load.
My 680 doesn't do the "boot time blast". Frankly I take that as an improvement over the 5770, and not as a problem at all.
Got a tip for us?

Actually I was just wondering if the GTX 680 was drawing too much power at boot, causing this no "fans blast" issue, possibly ending to some damage. Sounds like it's not, all fans are indeed working at normal speed after login.
Just got used to this huge startup fans noise after 4 years of Mac Pro use, got worried it suddenly disappeared.
Thank you!

ZOTAC GeForce GTX 680 4GB [ZT-60103-10P] confirmed.
The card has 2 x 6-pin connectors.

Same issue
If login and open any image file, PCI-fan comes speed to 2070 rpm, and then decreased to 800. PSU-fan also grows up to 1300, then dropped to 600 rpm. And until next switch off/on a MacPro fans spinning normally.I just bought this card.
Asus GTX680-DC2O-2GD5

Have not got hold of the mini pcie 6 pins cables though so I have not yet tested it. I'm going for a 6-pin to 6-pin + and 6 to 8-pin to the card.
Any problems you think? I'm going to flash it later on when I get all the needed cables that I've ordered.
Mac Pro 2009 with 5.1 FW and upgraded with a Intel Westmere Xeon W3670 3.2Ghz CPU.

This is one of the more exotic GTX680 models that could be significantly different from the reference design, especially the triple slot width. I am quite certain that no one on this forum had reported flashing this model before and I'd strongly urge you to save a backup copy of the original ROM before flashing. Please keep us updated on this one.
What is different than just the better cooling solution and clock speeds?
The triple height is just for the better and larger fans.
The MSI Twin Frozr seems to be kind of the same and that one worked as reported.
It will just end up with the ref. clock speeds.
Well... on the other hand....

This will be an expensive flash if it goes wrong.

The video you linked mentions a feature called "VGA Hotwire", and that alone would give me a long pause before considering flashing. It's a proprietary feature not in the reference design, and no idea how the ROM was altered just to accommodate this function.What is different than just the better cooling solution and clock speeds?

Yes, I know. All these features will be lost with the EFI ref. ROM.
The mystery is if the card still will work as a ref. card but with a better cooling system.

Question:
Can I "underclock" that Asus card back to ref. clock speeds? Just to be safer with the TDP?
This if I decide not to do the risky EFI flash. :-O

Took a gamble. Can confirm that this cards also works with the vanilla mac rom flashed! =)
10 sec delay before gray screens. (Made me really scared at first).
PCI fan acts weird from time to time. Been reported before I guess.
Have some issues.
Playable games:
BF Bad Company 2 : many hours on maxed out settings.
Crashing:
BF3
BF4
COD MW2
The settings do not seem to matter if I max them out or not. Freezes and sometimes black screen. Getting 2 kind of errors signs.
Some DirectX error and some that the gf driver stopped working.
Do your ref. 680's play BF3 and BF4 without "issues"?
Will try with a sep. PSU today. Is it just to connect it to the card and then power on, then start the Mac Pro?

I've yet to find a rock solid stable bf4 on anything never mind just a Mac Pro with a 680 unless you turn the settings right down - had black screens on both nvidia and ati cards, most recently an ati at the weekend that ran fine on low yet bombed out and bricked the system totally on medium. Needed a 3/4 hour chkdsk /r to fix the disc corruption after!
It needs a good few months more to get stable before I will even consider playing it on mine or even for the boy. He can stick with black ops 2 for a while longer!
BF4, yes. 140+ hours and no crashing issues.
Yikes!
I know this isn't helpful, but it works for me (2010 MP and GTX 680). I did the campaign on Ultra settings and do multi-player on High settings.
Sigh. Guess I have to buy another 680 then.
Which ones do work without fan issues and 10 sec delay at startup?
I also tried to run the card with an external PSU today and still BF3 and BF4 crashes on me.
Uniengine benchmarks also runs flawless even with overclocked original rom.
Damn you Dice!

get an EVGA PC model 02G-P4-2680-KR
then flash the MAC EFI ROM, that card is identical hardware wise to the Mac Edition.
Just ordered a brand new 02G-P4-2680-KR. 3000 SEK!
The Asus card I got for only 1900 SEK.
Will report back when I get it.
Works for some and bricks others, a lottery cos I've seen it happen to old and new Windows installs and Nvidia and ATI. Monster game with knock-out amazing leading edge graphics when it is working great, but not stable enough for me to risk the brick lottery for my systems in the house despite all having SSD's so the disk check wont take that long!
Got it today.
Still 10 sec delay before grey screen.
Still fans go crazy on cold start.
Will do some game tests now.
That actually seems to work! =D No more crazy fans at cold start!
All games also runs fine now! No more freezes and crashes on any game!
BF3, B4, Skyrim etc. all runs fine at ULTRA.
All smooth except the 10 sec delay before grey screen then =)
Any ideas why the 10 sec delay happens?
Do this happen to all flashed cards?
If not which card, mac pro and output are you using?
I'm using a 2009 mac pro with 5,1 FW.

It's not supposed to have a 10-second delay especially when using the EVGA reference card. Where did you get the Mac ROM? if I were you, I'd download from here and reflash it again.
