I'm running a BFG 7950 GX2 w/ e6600 on 1920 x1200 res. While playing COD2 last night for about 30 min. the hottest of the two cards got up to 83C with the other 77. I have three 80mm fans blowing cold air into the case and a 120mm pulling hot air out.

Just wondering what temps others were getting with their 7950 GX2? and if there are any good cooling solutions to add?
 
Same here. 1 GX2, Superlanboy, fan controlled 120mm fans. When I had my 78000GTX's in sli the top card would hover around 86-88c with the bottom card 15 degrees cooler. Long sessions in Jalalabad last night satified my temp worries.

<edit>
specs:
3200 venice @ 2.6Ghz +0.15v
2x1024 Gskills @ 260 2.7v
1x Raptor 8mb, 1x Seagate 320
Antec True Control 2.0 550W
Zalman 9500
 
Yeah my GX2 gets to around 75-80 under load. It's strange - Tiger Woods 2006 starts artifacting and doing weird graphical glitches when I've been playing it for more than 20 minutes or so. Anyone else have this problem?

Other games like Oblivion, CS Source, DoD Source etc run fine at that temperature, its just tiger woods that plays up...strange.
 
well if you are seeing artifacts then you probably have either :

1.under powered PSU

2.High case temps causing overheating

3. faulty card


whats your PSU +12 ratings? and total wattage?

also keep in mind that the 7950 runs 2 GPU's and 2 sets of 512 megs of DDR3 so that will produce some high temps regardless.
 
@ halo, yup I see artifacting on COD2 however I don't see it on BF2

@ Godmachine, the case is very cool and ventilated. I am ashamed to say that I'm still running a 400w Antec. However, I did order a 600w OCZ (700w peak) yesterday that should solve any under power issues.

I was thinking about adding this side fan and attaching the thermal sensor to the cooler card. So as the cards heat up they would get more air across them.
 
FIRST READINGS WERE 57 AT IDLE AND 73 TO 77 AT LOAD. PUT A 120 FAN BLOWING IN RIGHT AT THE CARD AND THE TEMPS ARE 46 IDLE AND 62 FULL LOAD.
 
I have gotton 0 artifacts and untill i improved my case cooling i was seeing 90 c core temps without issue. I see 70 c load now but if your seeing artifacts your card is defective imho.
 
It's weird though, I only get the artifacts in Tiger Woods PGA Tour 2006 after playing for about 20 minutes or so. That makes sense that it could be a heat related problem, but I play Track mania Nations with all the graphics on max with no slowdown and 0 artifacts.

Oblivion, which is most likely more graphics card intensive than most games can run fine for hours too.

I think it's just Tiger Woods 2006, bloody strange eh.
 
I guess you just have to play speed golf for 20 minutes.;)

I'm building a new system in about a year and a half and will probably be installing something like this. I'm going to try and use the same full tower Lian-Li case, so hopefully my card will run cooler. I still can't believe video cards are up to 1GB already. :eek:
 
Haha, well I guess I'll just have to take less shots in the game to speed it up then eh :p

Yeah, I've come from using ATI Cards, I had the legendary 9700Pro when it first came out, then the 9800Pro and then went to the X800XT, all excellent cards.

After switching to NVIDIA for my new Core2 Duo system I'd have to say that I'm impressed with the NVIDIA 7950 card. I was always under the assumption that ATI > NVIDIA for image quality but to tell you the truth, with a decent monitor (I'm using a Dell 20" widescreen 2007WPF) and correct brightness/contrast, all games look the same if not better.

I'm getting ~15,000 3dMark 05 points so everything's definately set up right.

By the way I'm using the Antec P180 Case which I feel has sufficient cooling.

It's 512.
 
From what I've seen some 7950gx2 bios's have the fan locked at lower speed. My evga was at 35% but a simple bios edit fixed the problem. At 100% the fans are very loud, to me at least, but at 65% they're still quiet but you should still drop quite a few degrees. Some people have been able to use RivaTuner to control the fan speed, so you could try that as well.
At 65% fan speed, my idle was 49C and load was 62C.

How did you edit the bios? I've tried rivatuner and coolbits and neither seems to do the trick.
 
Mine was idling at 60-65c and getting to 75-78c under extreme load (Oblivion etc).

What I did was install 2 additional low-speed 120mm fans in my P180 case. One went in the front to draw in cool air from outside the case, the other I mounted in the centre HDD bracket so it's taking the cool air from the first fan and circulating it straight over the 7950gx2. The temps have come down, mostly load temps.. idle is now 52c and under load I haven't broken 65c yet. II'm trying to get the card under 60c load to keep the fan speed from revving up.

I don't think the stock cooler does a very good job, I'd like to see an aftermarket cooler for the 7950 series if they are going to be more and more popular with gamers going forward.

I was curiuous as to whether it would also be worth pulling the Heat sinks off the 7950gx2, reapplying decent paste like AS5 and reseating the HSF. I have done this with a few ATI cards and gotten temps down between 2-5c doing so.

Man I wish you could use VF-900's on these cards. Problem solved.
