Hi there.

I have the following specs.

i5-2500k @ 4.5GHz
2x MSI 570 twin frozr III power edition cards
cooler master sniper case

rest is irrelevant to my question

I have all the fans installed and at max speed when overclocking the cards to 850mhz @ 1.035v core and 2000 memory In Crysis 3 max settings with FXAA it's about 75C hottest card. So I was thinking maybe there is a mod or if I can replace the side fan with better quality 120/140mm fans. on idle it's about 40-45C and lower on 40% fan speed.

thanks
 
There's no need to, they run perfectly fine at those temps.

so what temps should I be looking out for. I mean my highest temps for intensive gaming let's say 4+ hours per day. I really want to push my overclock a bit further without taking the card apart.

Probably around the temperature they reach with stock cooling at stock speeds is what you should get with overclocking and upgraded cooling. I don't really know what the ideal temperature is, but under 80 should be fine. They'll usually underclock or turn off when overheating but don't count on it. I know Intel publishes max temperatures for their CPU's, maybe you can get the same information for graphics chips. Replacing a case fan won't make much difference anyway, unless your existing one is busted, or you plan on cutting a new opening and adding more.

All I know is my Radeon HD6870's sometimes run at around 85 for hours and they're at stock speeds.

Hi There,
I am with TJ99 run it for a few hours at normal clocking and check the temperature and then start overclocking it. Obviously the cooler you can run it the better in terms of speed the better.
If it gets too hot ie in the 90sthen you are going to need to look at cooling options before the solder weakens.

ok I ran everything stock and it works at about 65-70C hottest card. I know due to sli the top card will run hotter that the other one. Now running into another problem. with a core clock of 880MHz +44(1.044v) and memory of 2190 (30mv) I also increased my aux voltage to 10mv I can play cryssis 3 at full gfx with motion blur on high and FXAA for about 30min-1hr no crashes but in bf3 even with vsync enabled I get crashes. it will tune me a directx error. I mean if it can run crysis sure it can run BF3. oh swapped the cards around and my temps dropped by about 1-4C and that's on the new speed.

BTW I play with Vsync on. that's reducing the strain on my cards and in my opinion feels smoother. I also get tearing with it off.

Fermi cards were pretty happy running at 80 degrees, so you're well within the norm for a GTX570. Are you on the latest Geforce drivers?
 
yes. 314.22. What is the max temps for my cards. Nvidia says 97C but can I run 85-90C for about 4hr gaming a day?
 
What's your cable management like? I got my second GPU a coupla weeks ago to run Crossfire. It got quite hot very soon (although not as hot as yours) and so I spent some time to really tidy the inside of my case. Good cable management can really make a huge difference in temps since you'll have better airflow.

If Nvidia says 97 degrees is the max safe core temp you can run it like that for 24 hours a day, but the moment it goes over your card(s) will clock down or cause errors such as the system hanging. Remember your cooling system can only take you to ambient + x degrees, so if it runs on 90 degrees in the morning, an 8 degree increase during the day will likely cause trouble.

thanks for the info
 
If you had the graphics cards for a few years, it could make a big difference by simply replacing the thermal paste again.

to scared to do that as the cards are still under warranty. I though maybe I can get one of those 3-in4 cooler master bays and remove the hard drive cage from my case so the front fan have more room to intake air. Going to do it tomorrow and will let you guys know

Removing the hdd cage made a huge difference for me. Card temps went from 90 to 70.

what case do you have?

I couldn't get myself ta 4-in-3 device module.
