 Anyone else have this problem or know of a fix?

Temps climb upwards of 85+ degrees and the fan gets really loud. GPU utilzation shows around 60-65% for both GPUs.

I am running a 1920*1200... VSync is enabled. All options max except for AA which is at 2x.

Help. It's to the point where I don't even want to play this game anymore for fear of tearing up my video card.

How long have you had that card? Did you have a look at it running while you are playing that game it sounds either clogged up or it's fan has failed.

Does the problem only occur while you're playing DAII or does it happens when you run other games or any other program which require a graphic card worth mentioning?

[mcsupersport]

How much clearance room and air flow do you have around your card?? If you have another card or something close to the intake area of the fans it will greatly reduce the cooling. I am running a 6970, which is a bit less than half your card but on almost exact same settings my card only pushes 68C, so something is wrong with the cooling of the card more than the game causing an issue. The card should be able to run at max and NOT overheat or get much above 75-80C if everything is working perfectly. The card shouldn't be hurt until it tops 100C anyway but why push it.

I have had the card since launch. I can assure that it is not clogged. I have a whole box of canned air and I use it regularly. I can also assure you that fan has not failed. The thing sounds like a 747 taking off.

The problem only occurs when playing DA2.

I have at one point or are currently regularly playing the following games without the fan ever needing to spin up:

Shift
Shift 2
NFS: Hot Pursuit
Dirt 2
Dirt 3
Bad Company 2
Rift
Demigod
Witcher 2
Crysis 2
Portal 2

There is plenty of clearance. There is only one card two slots below it. (about 2 and 1/2 inches down) It's a sound card is and is not even half the length of the 6990 so it doesn't even extend to the middle of the card where the fan is on the 6990.

The case is an Antec Nine Hundred Two. The 6990 is in the top slot. The top drive cage fan is reversed so it blow the hot air from the exhaust right out of the case.

I can assure you guys it's not an air flow issue.

Are you also running optional high resolution texture pack and using the DX11 renderer?

[dinria]

I'm sorry to say that I don't have any idea on what causes the problem but I can say that it's unlikely that the problem is that the game is to heavy. I'm running on the same settings as you except for the resolution which is set on 1680x1050 on a Sapphire Radeon HD 6850 (standard clocked) without any problem I've noticed.

[k1DBLITZ]

I'll try adjusting the resolution as a test. In my searches for a fix I ran across a thread that mentioned some bug at 1920*1080 and possibly 1920*1200....

I monitored the card more closely last night and it seems to top off around 85-87 degrees celsius... Which is still insanely hot... You wouldn't believe how hot the surface of the card is at that temperature.. It actually burned my fingertips.

Your power supply can't support the card. I had the same problem until I upgraded my power supply.

Running the high res pack, DX11 and 2x AA(tried four but it dropped the fps to mid 20s too much) iirc, on a MSI 6950 twin frozier, pulls 35-45 fps during most of the game with only occasional dips into the high 20s at high loads.  My card runs pretty constantly 65C with maybe a 68C as a high, on the easier sections I will see high 50sC.  Right now just surfing the net it is running a cool 41C.

In response to the poster above, yeah, I could easily believe it is a psu issue.  Not many people run 1200W PSUs and if they degrade any due to being poor quality or bad manufacture it could cause an issue.

So K1DBLITZ, what is your powersupply rated at, who made it and how old is it?

[Darth333]

= Not many people run 1200W PSUs...

Although the OP's issue could be caused by a cheap, inefficient or old PSU, the 6990 doesn't require a 1200W PSU.  The wattage is not all. A quality 800W PSU can do the job very well.

@Darth
You may be correct, all I read a month or so ago about the 6990 said a 1200w was spec, but I never really looked super hard at it because the card was out of my budget.

Oh yeah? And how do you know what power supply I am using? And please explain the logic behind a power supply overheating a video card? (hold on, let me get some popcorn)

I'm running a Corsair TX850w power supply. It will be 2 years old in October.

Amperage is rated at: +3.3V@30A, +5V30A, +12V@70A, -12V@0.8A, +5VSB@3A
But I'm sure you knew there is more to power supply ratings than just watts, right? 

The absolute max power draw from a 6990 is 375w standard or 450w if using the alternate overclocked BIOS. I am using the former.

Please take a moment to educate yourself: http://forums.atomic...p?showtopic=264

It absolutely does NOT require a 1200 watt power supply.

Do you have any way to know what the fan to temp curve is supposed to be? I had a 250 card and the fan didn't top 60% until 75c, so is that how the card is supposed to act?

[mcsupersport]

I also noticed Crysis2 on your list, is that with the dx11 dlcs allowing ultra graphics, or stock game?

That is with Ultra. There were 2 additional downloads required if I recall correctly.

Yes, the stock fan settings are very non linear. They have it configured to get by with as little fan as possible until it reaches a very narrow window and then they crank up the fan speed. 

You can download a free program called MSI Afterburner (works with all brands of cards) and adjust the fan speed however you'd like.

For example, you can create a linear pattern so that the fan speed slowly increases with every degree.

@K1dblitz,
Yeah, I tried the Crysis2 ultra setting, but my card ran it about 12fps, so I had to cut it back to extreme and it pulled around 40 which is decent playable. Maybe with more play I could tell more difference but to me I didn't see a huge jump in quality for losing 25fps and making the game unplayable for my card. I would love to be able to afford the 6990, but it is out of my budget, can't make myself spend the extra 500 or so dollars when the wife and kids need/want their own toys. I looked at the 6990, read some, saw the price and then forgot about it.

Yeah, MSI Afterburner is great, and I modified my Nvidea250 card fan pretty heavily to run cooler, but this 6950 Twin frozier hasn't had to be modified to run cool(yet).
I know DA2, heck even DA:O, isn't known for being easy to run, the coding from what I have heard isn't well optimized. I wonder if that plus the DX11 components simply means lots of stress on the graphics cards and as such you would need to boost the fan to keep the temps lower.
If you have checked the fan air flow, clearance, operation, and have the latest drivers, I don't know anything else to say check off the top of my head. If you do find out a cause, other than just a poorly written code in the program, let us know. Maybe sami jo, or Gorath will stop in and have a better idea, since one knows the DA programs well, and the other is pretty good on hardware.
