Notice Use this info at your own risk
If you use riva tuner hopefully you know how to find your max gpu temperatures. If you don't know how to find this or don't know what this is,,,, STOP NOW!
Before coming to the speed settings mentioned below I of course played around with different speeds before getting a range that seemed to work. All video cards are different and all systems respond differently so don't take my numbers for the perfect solution, but more as a reference for what to try.
Nvidia 295 GTX 576 X 1242 X 999 /w an I7 940. Just played around with this tonight so I dont have long term data. Using Riva Tuner I dropped my Core Clock speed to 325, linked shader = 700, memory speed = 550. I played around with the fan and settled on 85% which is not great but is better then 100% which is what it stays at any other time. In the Nvidia control panel I select 1 gpu mode (this only seems to keep the temperature from rising faster). On a 295 though 2 gpu's only bump the frames up 2-5 fps anyways, so when you are already dealing with 55-60 who cares. Then inside the game all settings maxed out with a 1920 x 1080 rez. In my quick test im running 93 celcius and 26-28 fps both seem to be stable. This is in the hanger over looking the ship which produces more heat then if in a dog fight. The stock clock and memory settings do run the game at almost constant 60 fps but with 95+ celcius and constant 100% fan. So for me assuming it doesnt cause issues while playing outside of the hanger or video card issues this is a small fix that I can live with. On this peticular card going lower on the settings will reduce the heat but results in less then 25 fps in hanger. I will post again once i've done more testing.
As far as cpu goes my fan never gets loud enough to over power the noise of any other fans in my system. I have played around with affinity on Eve and found that multiple cores def are utilized and compared to most games, utilized quite well. I use vista so I was quite surprised to find this out. I will play around with the above settings and see if dropping to 4 and 2 cores still runs the game well as this maybe could be an option for someone with high cpu noise. Also I use a stock cooler for the 940. The case has a 120 mm low rpm fan in the front and 1 in the rear. The power supply is a 140 mm low rpm which exits the rear. Ambient temperature is between 76-80 F (24.4-26.6 C).
As far as the heat issues I can gain or reduce the temperature a little more by not covering the drilled out portion on the side, however this causes more noise being that the gpu fan is close by. Also if you can stand/afford to have your ambient temperature lower than 76 F then this will also make a big difference in the temperatures.
Of course as mentioned in other posts make sure all your fans aren't being blocked by dust as this adds heat/noise very quickly. I hadnt checked my front fan in a while and realized it was 95% blocked. Just by clearing off the dust I dropped around 8-10 C on average on the gpu just by fixing that. For a short time I played AoC and found that there again heat was an issue. In that game I had to stick closer to stock settings so a 500 core speed. Again it made a big difference in heat. This peticular card seems to be a beast and will take anything I throw at it, as long is the fan is running at the right speed for the job.
As far as Physics, I am running Nvidia and all my ati cards have died, so this doesnt affect me. When playing Mafia 2 with physics I found that the 295 just doesnt have enough umpft to make it work in that game. So I just turned it off.... but that game already looks really good anyways so I didnt mind. I would definately miss the effects in Eve, so hopefully someone can figure out a fix. The only thing I might mention on that subject is rather then going liquid cooling, maybe look into a better air cooler for the cpu. I look at tomshardware for stats on this type of thing, or wherever you go. |
