Switched my order to a DCII, had the same cooler on a 280X and cant complain at all about it.
Should have it by Wednesday biggrin.gif

The ACX coolers are awesome. Nice cooling for the core plus VRMs. I've owned 11 EVGA GTX 780s (all of them with ACX bought between July 2013 and November 2013, no problems on any of them). There were some problems with the cooler with vibrating fins that got sorted out in mid 2013 (if I remember correctly). I'm sure a lot of the problems you found were from before the fix in 2013. If you have a problem with noises from the ACX EVGA will do an RMA for you.

One defective cooler doesn't make the ACX "garbage."

The ACX models are a-ok in my book. The cooler design is classy and effective in cases with good airflow. /unbiased opinion (ACX FTW owner) wink.gif

I'm entitled to my opinion and I'm honestly quite glad you have a perfect experience with your 11 cards. EVGA and every single reviewer claimed the ACX was the best thing ever. Not one mention of any noise -- I'd reckon some people can't even hear it -- maybe you're one of those people. Your set up is completely different to mine and I'm not sure how quiet or loud your system runs. Mine is set to be very quiet as I hate noise. I'd even go so far as to say I hate the sound of a Velociraptor drive like you have listed in your build -- I owned a 150GB and a 300GB a few years back.

I paid full price on launch for mine and sure as heck would want them to come out of the box perfect, not with loose fins (I also tried that route and even though I did find and stuck some thermal pads on those loose fins, I get the same noise). Also, after reading that hardforum post, I'm not too keen on spending time to try to get two working heatsink/fan assemblies.

Oh and btw, I own two, not one. Both make the same noise at almost the same RPM. I found a newer bios that allows for 29% fan speed and I setup AB to keep it at that speed until about 50C -- which is perfect for viewing movies and playing quite a number of not-to-complex games.

No clue if the number of people with this problem is large or not, but it's not just one -- it's at least two, which is the number of cards I own and can speak for.

If your fans are making any noise other than those associated with airflow, RMA them. Here's a quick video of my GTX 780 ACX FTW running at fan speeds from 40-100% at 10% intervals. No unusual noises to speak of (And I know what bad bearings, bad fan blades, etc sound like tongue.gif)

And for the record, I only run quiet systems wink.gif

Eh all I know is I already had a DCII on the card this is replacing and didnt have a single complaint w/ it. Good enough for me.

Hopefully its a good chip and I can get a decent OC on it smile.gif

I can't comment on the incidence of problems with the ACX, and I'm not denying they exist. Maybe part of the problem is that you bought at launch (when EVGA admitted there were problems with the ACX). You might want to try the RMA route and see if it helps. And I remember when a new BIOS came out to peg the fans at 29% to help with noises from the ACX.

The Velociraptor is dormant for the time being. It was an overflow for my SSD for Steam games, but I just got a 750GB Samsung Evo so I've got space on my OS drive for games at the moment.

I wouldn't call my computer quiet, though I've tried to find a balance between noise and performance and have purchased quiet or PWM fans where I can to cut down on the noise. I'm pretty sensitive to noise (it always makes me cringe a bit to hear coil whine / inductor buzz when OCing and benching my video cards) but probably not as sensitive as you are. The loudest part of my setup is the 2 x GTX 780 Classifieds with a custom (more aggressive) fan curve.

With clocks at 1350 @ 1.3v the Power % is going to 105-115% is some games. The PT slider is already at 150%.
Does that mean that I can't increase the clocks over 1350 because my card can't draw extra power anymore?
At 1360 core I crash, but not sure weather is because of PT max or my core simply can't do more without more voltage.
What is I increase the voltage more? Would I be able to get more core speed or am I already limited PT at 150%?

The Ghz Edition was by far the best card I reviewed plus the WF3 has a 8+2 phase VRM, directly cooled by the main heatsink, and they're controllable with the NCP4208 the card has. MSI AB has no problem doing 1.30v on them and i'm not afraid to run the card at that voltage either in terms of VRM's.

I was thinking about the gigabyte, but these FLIR images:

http://www.guru3d.com/articles_pages/evga_geforce_gtx_780_ti_sc_acx_superclock_review,9.html

Plus the vdroop (had it before - hated it) and the possibility that I may not get a B1 chip made me go with the ACX.
